Product Overview

3 Product Overview

3.1 General Information

SIWAREX FTC (Flexible Technology, Continuous Weighing) is a versatile and

flexible weighing module for belt scales.
The function module (FM) SIWAREX FTC is integrated in SIMATIC and uses all
features of the modern automation system such as integrated communication,
diagnostics system and project planning tools to its advantage.
The scale functionality of the SIWAREX FTC includes the non-automatic scale
(Non automatic weighing instrument conforming with OIML R-76), force
measurement and belt scale.

3.2 Benefits

SIWAREX FTC is characterised by a few clear advantages:

o Uniform structure and universal communication through the integration in the
SIMATIC S7 and SIMATIC PCS7

o Intrinsically safe load cell supply for Ex-Zone 1 (optional)
o Application in Ex-Zone 2
o Extensive diagnostic functions

SIWAREX FTC 3-5

3.3 Range of Application

SIWAREX FTC is the optimal solution wherever weighing technology requires high
speed and precision. Because of the high resolution (3 x 6000 d, calibratable),
scales can be built to work precisely over broad areas. With the SIWAREX FTC
weighing systems, force measurement systems and belt scales can be
constructed.

3.4 Structure
SIWAREX FTC is a function module (FM) of the SIMATIC S7-300 and can be read
directly on the SIMATIC S7-300- or ET 200M bus board. Installation / cabling
efforts for the 80 mm wide module are simplified with the profile rail assembly
(snap-in technology).
Connecting load cells, power supply and the serial interface is all done through the
40 pin standard front connector.
Operation of the SIWAREX FTC in SIMATIC guarantees complete integration of
weighing technology in the automation system.

3.5 Function
The primary task of the SIWAREX FTC consists of the precise measurement of the
current weight values in up to three measurement ranges and the exact
measurement of the amount of the uploading material.
There are different weighing procedures for which SIWAREX FTC can be
configured optimally by defining the corresponding parameters.
The following operating modes can be defined:
- Non Automatic Weighing Instrument – conforming with OIML R-76
- Force Measurement
- Belt scale
During the weighing procedure, SIWAREX FTC monitors and controls a multitude
of signals. The optimised system internal data exchange enables a direct
evaluation of weighing signals and states in the PLC program.
The weighing procedure influence on the PLC enables a flexible adjustment to suit
the changes in the system technology.
SIWAREX FTC is already adjusted in-house. Therefore, the scale can be adjusted
to theoretical settings without using any adjustment weights and modules can be
exchanged without readjusting the scale. Exchanging modules during running
operation is also possible when working with "active bus modules”.
The SIWAREX FTC has two serial interfaces. An RS 485 interface is used for
connecting digital remote display (only for the application as non automatic
weighing instrument). A PC can be connected to the RS 232 interface for setting
SIWAREX FTC parameters.

3-6 SIWAREX FTC

Product Overview

The weighing module SIWAREX FTC can also be used in explosion hazard areas
(zones 21 and 22). Load cells are supplied with inherent safety with zone 1
applications using an optional Ex-interface SIWAREX IS.

3.6 System Integration in SIMATIC

SIWAREX FTC is completely integrated in the SIMATIC S7 and SIMATIC PCS7.

The user is absolutely free to configure his automation solution including the
weighing application as desired. The optimal solution can be created for small,
medium and large systems by selectively combining the SIMATIC components.
The project planning package and the example application SIWAREX FTC "Getting
started” can help you to quickly and efficiently create customer specific or branch
specific solutions. The following image shows a typical assembly for a medium
sized system.
For project planning with SIMATIC PCS 7, the completed function block FB SIWA
for the automation system and the graphic blocks for the operator station are used.

SIWAREX FTC 3-7

3.7 Commissioning and Service with SIWATOOL FTC

For commissioning, there is a special program SIWATOOL FTC for Windows

operating systems.
The program enables commissioning of the scale without having to understand
automation technology. During a service procedures, you can analyse the
processes in the scale and test them with the help of a PC. Reading the
diagnostics buffer from the SIWAREX FTC is very helpful in analysing events.
Besides complete access to all parameters, memory or print-outs of the weighing
file, the program can create weighing curves as well.
SIWATOOL FTC can also be used for reading the contents of the calibratable
records from the calibratable scale memory.
The following image shows the structure of the individual program windows.

Image 3-2 SIWATOOL FTC Overview

Not only does the SIWATOOL FTC support the user for program entry. Analysing
the diagnostics buffer, the contents of which can be saved together with the
parameters after reading from the module is also very helpful.

3-8 SIWAREX FTC

Product Overview

A trace mode exists in the SIWAREX FTC module for optimising weighing
progress. The recorded data can be displayed in a curve diagram using the
MS Excel.
The trace information can be used for analyzing the work of a plant during a
defined period of time.

3.8 Firmware Download with SIWATOOL FTC

Another feature of the SIWATOOL FTC program helps loading a new firmware
version for SIWAREX FTC on-site. It allows you to perform firmware upgrades at
any time and from anywhere.

3.9 Reading the stored weighing logs with SIWATOOL FTC

The weighing logs are stored on an MMC (Micro Memory Card) that is inserted into
the SIWAREX FTC for the period of time defined in the weights and measures act.
If a person disagrees with the results of a certain weighing procedure, the weighing
data for that weighing procedure can be reconstructed from the MMC memory.

Selecting the suitable SIMATIC CPU, the SIMATIC HMI (Human Machine
Interface) and communication modules does not only depend on SIWAREX FTC
requirements but also on the overall job that the automation system has to perform.

4.2 EMC-Compatible Structure

SIWAREX FTC is a high-precision measurement device which has to dependably

measure the slightest signal. Proper assembly and cabling is an absolute must for
interference free operation.

4.2.1 Definition: EMC

EMC (Electromagnetic Compatibility) describes the ability of an electrical device to

function in a defined electromagnetic environment without being influenced by its
surroundings and without negatively influencing the surroundings.

4.2.2 Introduction

Although SIWAREX FTC was developed for use in industrial environments and
meets high EMC specifications, you should do some EMC planning before

SIWAREX FTC 4-11

 installing your controller to determine and take into account any possible
interference sources.

4.2.3 Possible Effects of Interference

Electromagnetic interference can influence the automation system and SIWAREX

FTC in various ways:
- Electromagnetic fields that have direct influence on the system
- Interference that infiltrates the environment through the bus signals
(PROFIBUS-DP etc.)
- Interference through process cabling (e.g. measurement lines)
- Interference infiltrating the system through the power supply and/or protective
ground
Error-free functionality of the SIWAREX FTC can be influenced by interference.

4.2.4 Coupling Mechanisms

Depending on the means of distribution (conductive or non-conductive bound) and

the distance between the interference source and the device, interference can be
introduced through four different coupling mechanisms into the automation system.
Galvanic coupling

Capacitive coupling

Inductive coupling

Radiation coupling

4.2.5 Five Basic Rules for Guaranteeing EMC

If you follow these five basic rules, EMC can be guaranteed in most cases!

Rule 1: Large conductive grounding surface connections

Ensure that while installing the automation devices, a well-made ground

connection is made between the inactive metal components (see following
section).
Connect all inactive metal components and low-impedance components with
ground (broad cross-section).
Use screw connections on painted or anodised metal surfaces either with special
contact washers or remove the insulated protective surface in the contact areas.
Do not use aluminium if at all possible for ground connections. Aluminium oxidises
easily and is therefore less suitable for grounding connections.
Find a central location for connections between the grounding point and the ground
wiring system.

4-12 SIWAREX FTC

Hardware Planning and Assembly

Rule 2: Proper and organised wiring

Separate the cabling into groups (high-voltage lines, power supply lines, signal
lines, ground wiring, data lines, etc.).
Run the high-voltage lines and ground wiring or data cables in separate channels
or bundles.
Run measurement lines as close to grounding surfaces as possible (e.g. support
beams, metal rails, cabinet panels).

Rule 3: Fasten cable shielding

Ensure that the cable shielding is connected properly.

Use shielded data wiring only. The shielding must be fastened to ground using a
large surface area on both ends.
The shielding of measurement lines must be fastened to ground on both ends.
Run cable shielding directly under the SIWAREX FTC on the shielding channelling.
The shielding is to be run to the connection terminal.
The connection between the shielding rail / ground rail and the cabinet /housing
must be low impedance.
Use metallic or metal-plated connector housings for the shielded data lines.

Rule 4: Special EMC measures

All inductivity that is to be controlled should be connected with suppressors.

Use interference suppressed fluorescent lighting or incandescent lamps for
illuminating cabinets or housings in the immediate vicinity of your controller.

Rule 5: Uniform reference potential

Create a uniform reference potential and ground all electrical operational elements.
Run sufficiently dimensioned potential equalizing cabling if potential differences
exist or are to be expected between system components in the system. A potential
equalisation is mandatory for Ex applications.

SIWAREX FTC 4-13

4.3 Assembly on the Profile Rail

When assembling the SIMATIC components and the SIWAREX FTC, the assembly
regulations (AR) for the SIMATIC S7 must be fulfilled completely.
SIWAREX FT is assembled in the following steps.
1. Check for whether the SIMATIC bus connector is connected to the left of the
SIWAREX FTC in the module group.
2. Connect the SIMATIC bus connector for the following module group in the
SIWAREX if necessary.
3. Install the shielding strip under SIWAREX.
4. Hang the SIWAREX FTC in its place.
5. Fasten the SIWAREX FTC with 2 screws in the lower area of the module.
6. Label the SIWAREX FTC corresponding to your identification system.

4.4 Connections and Cabling

4.4.1 Connection areas for SIWAREX FTC

The following connection areas are found on the front:

- Screw-in connector for 24 V power supply
- 40 pin connector for load cell connection, digital input and output, RS 485,
analog output, counter input
- 9 pin (female) D-sub connector for RS 232 to PC or printer connection

4-14 SIWAREX FTC

Hardware Planning and Assembly

Image 4-1 SIWAREX FTC Front View

4.4.2 Shield connection

Special attention must be given to the shield strip for shielded lines. The
interference resistance of the system can only be guaranteed if the properly
constructed.
A cable is shielded to decrease the affects of magnetic, electrical and
electromagnetic interference on this line. Interference on cable shielding is routed
to ground through shielding rails that are conductively connected with the housing.
To ensure that this interference stream does not become a source of interference,
a low impedance connection to ground is especially important.
Use only lines with mesh-shielding. Shielding should provide at least 80%
coverage.
For fastening the meshed shielding, use only metal cable clamps. The clamps
must cover as much shielding as possible and ensure a good contact.
Shield clamps must be ordered separate to the grounding elements. The area
covered by the shielding clamp is to be chosen corresponding with the cable
diameter.

SIWAREX FTC 4-15

 Approximately 1.5 cm of the cable insulation must be exposed in the area of the
cable to be fastened with the shielding clamp. The exposed shielding is then
pressed firmly against the grounding element with the shielding clamp.
The following figure shows a proper shielding clamp assembly

Image 4-2 Shield clamp assembly

The shielding should be pressed against the shielding rail by the shielding clamp.

4.4.3 Connecting the 24 V power supply

The 24 V supply voltage is connected with a screw connector. The connection is

found in the lower area of the module groups next to the D-sub connector for RS
232.

Note
In central operation in the S7 300 system, the SIMATIC CPU and SIWAREX FTC
is to be connected to the same 24 V power supply.

The following rules are to be followed when connecting load cells.

SIWAREX FTC 4-17

 Using a junction box is required if more than one LC is connected (the LC must be
connected parallel to one-another).
If the distance from LC to SIWAREX FTC is greater than the existing length of the
LC connection cable then the extension box EB is to be used.

2. The cable shielding is normally run on the cable guide supports of the junction
box.
In case of the danger of potential equalisation currents on the cable shielding, a
potential equalisation conductor is to be run parallel to the load cell cable or the
shield clamp is to be used in the junction box to the shield strip. Using the potential
equalisation conductor is the preferred method of dealing with EMC
(Electromagnetic Compatibility).

3. Twisted pair cable is required for the indicated wiring:

- Sensor lines (+) and (-)
- Measurement voltage lines (+) and (-)
- Supply voltage lines (+) and (-)

4. The shielding must be attached to the shielding strip on the SIWAREX FTC.

4.5 Operational Preparation

Introduction At this point in the commissioning procedure, after assembling the module
group and making all connections, you should perform a partial functionality
test for the SIWAREX FTC and the connected components.
The individual steps for partial testing are to be performed in the following
sequence:

Visual check Check all previously performed steps for proper execution, i.e.:
• Is there any external damage to the module group?
• Are the modules situated in the proper positions?
• Are all fastening screws properly tightened?
• Are all connecting cables properly connected and fastened tightly?
• Is the frontal connection made properly?
• Is the shielding properly attached to the shielding conductor for all
corresponding cables?
• Is the profile rail connected to the ground conductor?
• Are all tools, materials or components that do not belong to the S7 or
SIWAREX FTC removed from the profile rail and
the module group?

Connect Switch power supply on.

SIWAREX FTC Proper initialisation of the SIWAREX FTC in the SIMATIC can only be
with 24 V supply guaranteed if:
- the S7 SPU (with decentralised connection with IM 153-1) and the
SIWAREX FTC are switched on at the same time
or
- the SIWAREX FTC is switched on first

LED check on the After attaching the 24V supply voltage and a short initialisation phase
SIWAREX FTC (internal testing is indicated by LED running pattern), the SIWAREX FTC
goes into operational status. The following LEDs must have the status that is

Weighing Functions

5 Weighing Functions

5.1 General Information

The SIWAREX FTC can be used either as a non-automatic weighing instrument,

force measuring system or belt scale. The operating mode is determined by the
application and is defined during scale commissioning.

The selected operating mode and the defined parameters are very important to the
behaviour of the SIWAREX FTC in the process.
The parameters are set with default values from the manufacturer. Using the "Load
default values" command, the parameter definitions defined in manufacturing are
loaded.

The default parameters are defined so that the scale is immediately ready for each
operating mode. Not all parameters must be re-entered for each operating mode.
By changing a parameter, the behaviour of the scale is changed respectively. The
advantage of this solution is that you can define how many default values should
be retained and how much that the behaviour of the scale has to be changed for
the application.

All parameters are split into data records (DR). The data records are organised
according to process steps (tasks) that you have to perform during the
commissioning phase or during the process itself.

In the following parameter description, you will find a description of the weighing
functions that are influenced by that parameter.
The parameters of a data record are shown in a table to start with. This is then
followed by the exact parameter description for the parameters of that data record.

After receiving a new parameter, SIWAREX FTC runs a plausibility check. If there
is a parameter error then the data record will not be accepted (stored) by the
SIWAREX FTC and a "synchronous" message is generated (see chapter 7
Messages and Diagnostics).

SIWAREX FTC 5-29

5.2 DR3 Adjustment parameter

The adjustment parameter must be tested for every scale and changed if
necessary.
The scale is basically defined using the adjustment parameter and by performing
the adjustment. In verifiable operation as a non-automatic weighing machine, the
data of the DR3 cannot be changed after calibration.
Procedure:
o Check all parameters and change if required.
o Send the DR3 to the scale
o Perform scale adjustment
o Receive DR3 from the scale

Weighing Functions

5.2.1 DR3 – Adjustment digits 0… 4, for the zero point and adjustment weights 1… 4

The analog measurement value coming from the load cells is converted into a
digital value with an digital-digital converter. A weight value is then calculated from
this digital value. All functions of the SIWAREX FTC then uses this weight value for
executing their task.
To calculate the weight value from the digital value, the characteristic curve of the
measurement system must be determined. In the simplest case, the characteristic
curve is defined by points 0 and 1. The first operating point (point 0) is always
determined with the empty scale alone with its own construction weight. The weight
of its own construction causes the load cells to deliver a measurement voltage to
SIWAREX FTC. After the digital-digital conversion of the measurement voltage, the
digital value (adjustment digit 0) is assigned the zero weight. For determining the
average value of the adjustment point (zero point, adjustment weight) over a
predefined period of time, the determination time must be defined. On a belt scale,
the duration of a belt cycle is set normally.
If the scale is loaded with a known calibration weight (e.g. with 50 % of the
measurement range), then the second operation point can be determined. The new
digital value from the analog-digital converter is now assigned the calibration
weight.
The characteristic curve can be further adjusted using a maximum of three other
points that must lie above point 1.
Ensure that the difference between two adjustment weights is at least 5% of the
measurement range.

The adjustment consists of the following steps:

Define adjustment weights and other parameters of the DR 3 data record.

Send DR 3 to the scale
With an empty scale, give the command "Valid adjustment weight = 0"
Load the scale with the defined calibration weight
Give the command "Valid adjustment weight = 1"
Receive DR 3 from the scale
Save the data to a data carrier

The adjustment sequence for the increasing adjustment weights must be retained.

Example:

Zero point = 0.0 kg (always) produces 5 800 000 digits

Adjustment weight 1 = 100 kg produces 10 100 000 digits

SIWAREX FTC 5-33

 This defines the characteristic curve (0 is entered as the weight value for further
adjustment weights) and the scale can now perform the calculations for the weight
values over the entire measurement range.
Note:
Since the maximum value for adjustment digits is 15 379 113 and the value for
completely empty load cells (without the weight of the construction itself) is 1 398
101. The plausibility of the characteristic curve can be roughly estimated to
determine load deviations for example.

The illustration shows the relationship between the adjustment digits and the
adjustment weight.

Image 5-1 Adjustment digits and weight value

If the adjustment weights and adjustment digits of a SIWAREX FTC are known
then the adjustment procedure does not need to be performed. They are simply
sent to the SIWAREX FTC in the DR3 data record and the scale is immediately
operational (after official calibration of the scale, it is no longer possible to send
DR3).

The SIWATOOL FTC program supports you in quickly performing and adjustment.

5-34 SIWAREX FTC

Weighing Functions

Option 1:
After commissioning and after adjustment, all data records for the scale are read
from SIWAREX FTC and are stored as a scale file ScaleX.FTC.
Identical scales can now be put into operation immediately. Connect the PC to the
new scale and activate the "Send all data records" function. This also transfers the
adjustment weights and the adjustment digits – the characteristic curve is defined
immediately. Of course, the same applies for exchanging a SIWAREX FTC.

Option 2:
Use the SIWATOOL FTC "Theoretical adjustment" function and determine the
characteristic curve of the scale from the technical data of the load cells alone. This
case assumes proper construction of the scale.

Note
Normally, defining two operating points is sufficient to determine the characteristic
curve for the scale. Other operation points must only be defined on non-linear
systems – New digital values (adjustment digits 2, 3, 4) are assigned with other
calibration weights (e.g. 70%, 80%, 100% of the measurement range).

Image 5-2 Linearization of the scale characteristic curve

5.2.2 DR3 – Characteristic value range

Depending on the characteristic value of the connected load cells, the value 1
mV/V, 2 mV/V or 4 mV/V must be selected. Since the SIWAREX FTC supplies the
load cells with approximately 10 V, the measuring input is redefined according to
the expected measurement voltage (max. 10 mV, max. 20 mV or max. 40 mV).

SIWAREX FTC 5-35

 For example, if the characteristic value of the connected load cells is 2.85 mV/V
then the next higher characteristic value must normally be set, i.e. 4 mV/V.

5.2.3 DR3 – Filter sequence of the signal filter

Changing the filter sequence can be an advantage in some cases. Normally, the
signal is first filtered by the average value filter.

5.2.4 DR3 – Type of low pass filters

3 types of filter are available to choose from, for suppressing interference

(critically damped, Bessel filter, Butterworth filter). The selection is performed
empirically. The following images show the step response of the three filters (fg = 2
Hz).

Image 5-3 Step responses of the digital low pass filter

5.2.5 DR3 – Limit frequency

Defining the limit frequency is critically important for suppressing interference. The
"speed" of the scale's reaction to the change in the measured value is determined
by specifying the limit frequency.
A value of e.g. 2 Hz leads to a relatively quick scale reaction to a weight change, a
value of e.g. 0.5 Hz makes the scale "sluggish".

5.2.6 DR3 – Depth of the average value filter s

The average value filter is used to settle the weight value against interference. The
weight value is based on the average of the n weight values that the SIWAREX

5-36 SIWAREX FTC

Weighing Functions

FTC calculates every 10 msec, e.g. if n=10, 10 values are used for calculating the
average value. Every 10 msec, the oldest value is removed and the newest is
taken into account in the calculation.

5.2.7 DR3 – Scale name

The name consists of a maximum of 10 characters and can be freely selected.

Note
The scale name can no longer be changed after official calibration.

5.2.8 DR3 – Number of weight ranges

SIWAREX FTC can be defined as a scale with one, two or three different
measurement ranges. Depending on the construction type certification, the
numeral step can be defined separately for every range.

5.2.9 DR3 – Scale type

If the number of ranges is greater than one then the scale type can be defined as a
multi-range scale or a multi-resolution scale.
Information on the function of a multi-range- or multi-resolution-scale can be found
in EN 45 501.
Note
If only one range is defined then this entry is meaningless.

5.2.10 DR3 – Activate zero setting upon switching on

The scale can be set to zero automatically by switching the supply voltage on. On
verifiable scales, a weight value of +/- 10% of the max. measurement range can be
set to zero on start-up.

!
Attention
In non-verifiable operation (no OIML restrictions), a full scale can also be set to
zero after activating this function. Limiting the effectiveness is possible by entering
the max. and min. weight however. See Max. Min. weight for zero setting upon
switch-on. This function is deactivated in the "Belt scale" operating mode.

5.2.11 DR3 – Activated zero setting upon switch-on, if scale tared

The scale can be set to zero automatically by switching the supply voltage on. If
the above function is activated, there is still the question of whether zero setting at
start-up should be run if the tare is unequal to zero.

SIWAREX FTC 5-37

 If yes, the tare is also deleted with the zero setting and if no, no zero setting is
performed on the scale.

5.2.12 DR3 – Automatic zero adjustment

Zero setting the scale can be performed with the "Zero setting" instruction if
required.
The automatic zero adjustment sets the scale to zero without an instruction if it
slowly drifts away from the zero point. Slow drifting is presumed if the conditions of
standard EN45501 are met. This function in the "Belt scale" operating mode will be
excecuted as dynamic zero setting function.

!
Attention
In non-verifiable operation (no OIML restrictions), after activating this function, the
scale can indicate zero after a slow drift over time if it is full. When using this
function, overloading the scale must be prevented with suitable measures.

5.2.13 DR3 – Minimum weight for weighing range 1

The weight value can be used for verifiable recording with the numeral step for
measurement range 1 only above the minimum weight. The minimum weight is
defined by an adjustment or a calibration. The minimum weight depends on the
number and type of load cells used.
The value can be set to 0 on non-calibrating scales.

5.2.14 DR3 – Maximum weight for weighing range 1

The weight can be used for calibrating purposes with the numeral step for
measurement range 1 only under the maximum weight. The maximum weight is
defined during adjustment.
The maximum weight depends on the number and type of load cells used.

5.2.15 DR3 – Numeral step for weighing range 1

The numeral step for weighing range 1 can correspond with standard EN 45501
(0.0001 to 50)

5.2.16 DR3 – Minimum weight for weighing range 2

The weight value can only be used above the minimum weight for verifiable
recording with the numeral step for measuring range 2. The minimum weight is

Weighing Functions

defined by an adjustment or a calibration. The minimum weight depends on the

number and type of load cells used.
The value can be set to 0 on non-calibrating scales.
Note
If only one weighing range is defined (as e.g. for the belt scale), then this definition
is meaningless.

5.2.17 DR3 – Maximum weight for weighing range 2

The weight can only be under the maximum weight for verifiable purposes with the
numeral step for measuring range 2. The maximum weight is defined during
adjustment.
The maximum weight depends on the number and type of load cells used.
Note
If only one range is defined then this entry is meaningless.

5.2.18 DR3 – Numeral step for weighing range 2

The numeral step for the weighing range 2 can correspond with standard EN
45501 (0.0001 to 50)
If only one range is defined then this entry is meaningless.

5.2.19 DR3 – Minimum weight for weighing range 3

The weighing value can only be used above the minimum weight for verifiable
recording with the numeral step for measuring range 3. The minimum weight is
defined by an adjustment or a calibration. The minimum weight depends on the
number and type of load cells used.
The value can be set to 0 on non-calibrating scales.
Note
If only one or two ranges are defined then this entry is meaningless.

5.2.20 DR3 – Maximum weight for weighing range 3

The weight can only be used under the maximum weight for verifiable purposes
with the numeral step for measuring range 3. The maximum weight is defined
during adjustment.
The maximum weight depends on the number and type of load cells used.
Note
If only one or two ranges are defined then this entry is meaningless.

5.2.21 DR3 – Numeral step for weighing range 3

The numeral step for weighing range 1 can correspond with standard EN 45501
(0.0001 to 50)
Note
If only one or two ranges are defined then this entry is meaningless.

5.2.22 DR3 – Standstill time

Stand-still monitoring is used for recognising a stable scale balance.

Scale standstill is determined if the weight value changes by less than a defined
deviation range (standstill value) within a defined time (standstill time). Standstill is
used in static operation of the scale (Command: Zero setting, Taring, Output log).

5.2.23 DR3 – Standstill range

Stand-still monitoring is used for recognising a stable scale balance.

Scale standstill is determined if the weight value changes by less than a defined
deviation range (standstill value) within a defined time (standstill time). Standstill is
used in static operation of the scale (Command: Zero setting, Taring, Output log).
The figure below illustrates the functioning of the standstill monitoring feature.

Image 5-4 Standstill monitoring

5-40 SIWAREX FTC

Weighing Functions

5.2.24 DR3 – Waiting time for standstill

To prevent having to cancel a weighing instruction (only taring, printing and zero
setting in static operation) immediately when the stable weight of the scale is not
defined, the waiting time is given as standstill. Only the scale instruction tare,
output log or zero setting was not possible after this time has elapsed is the
corresponding technology message generated.

5.2.25 DR3 – Maximum negative weight for zero setting upon switch-on

Zero setting means that an automatic zero setting is performed for the scale when
the supply voltage is switched on.
If zero setting upon switching on the supply voltage has been activated, then the
definition will limit the affect of the function. The reference point for the
effectiveness of the limitation is not the current weight, it is the weight that was
displayed by the scale without a previous zero setting. This function has no effect
in "Belt scale" operating mode.

5.2.26 DR3 – Maximum positive weight for zero setting upon switch-on

Zero setting means that an automatic zero setting is performed for the scale when
the supply voltage is switched on.
If the zero setting when switching on the supply voltage has been activated then
the definition will limit the affect of the function. The reference point for the
effectiveness of the limitation is not the current weight, it is the weight that was
displayed by the scale without a previous zero setting. This function has no effect
in "Belt scale" operating mode.

5.2.27 DR3 – Maximum negative weight for zero setting

The current gross weight of the scale is defined as zero for zero setting.
For zero setting, the specification can be used to limit the effect of the function. The
reference point for the affect of the limitation is not the current gross weight. It is
the weight that the scale would show without a previous zero setting.
For scales in calibrating operation, the limit between the negative and positive
weight for zero setting is 4% of the maximum weighing range.

5.2.28 DR3 – Maximum positive weight for zero setting

For zero setting, the specification can be used to limit the effect of the function. The
reference point for the effectiveness of the limitation is not the current weight, it is
the weight that was displayed by the scale without a previous zero setting.
For scales in calibrating operation, the limit between the negative and positive
weight for zero setting is 4% of the maximum weighing range.

SIWAREX FTC 5-41

5.2.29 DR3 – Maximum tare load T-

SIWAREX FTC accepts every weight value which is less than %-record of the
maximum weighing range with multi-range scales or weighing range 1 with a multi-
resolution scale.
On scales in verifiable application, the value is limited to 100% of the maximum
weighing range.

5.2.30 DS3 – Scale operating mode (Scale type)

This parameter is used to select the suitable weighing instrument program. One of
these weighing operating modes applies depending on the task description.

5.2.31 DS 3 - Weighing operating mode: NAWI Filling Procedure

Non-automatic weighing instrument – according to OIML R-76 – only accepts

service and adjustment commands and "zero setting" and "taring" weighing
instructions. The net weight increases with increasing load on the scale. No belt
scale functions are supported..

5.2.32 DS 3 - Weighing operating mode: NAWI Emptying Procedure

Non-automatic weighing instrument – according to OIML R-76 – only accepts

service and adjustment commands and "zero setting" and "taring" weighing
instructions. The net weight increases with decreasing load on the scale. No belt
scale functions are supported..

5.2.33 DS 3 – Operating mode: Force measurement

This operation mode can not be used for legal trade. The functionality is the same
as in the operation mode “NAWI filling procedure“. The difference is only the plus
and minus polarity for the measuring signal.

5.2.34 DS 3 - Weighing operating mode: Belt scale

In this operating mode SIWAREX FTC will use the parameters of DR5. The
Functionality supports belt scales.

5.2.35 DR3 – Regulations

Scales in calibrating operation are subject to certain restrictions. The "OIML" entry
activates these restrictions. To deactivate them, it is necessary to enter "----". The
entry "OIML" only makes sense if the scale is to be verifiable as a non-automatic
weighing instrument.

5.2.36 DR3 – Unit of Measurement

A 4 character string can be used as the unit of measurement e.g.: g, kg, lbs

5-42 SIWAREX FTC

Weighing Functions

5.2.37 DR3 – Large Unit of Measurement

A 4 character string can be defined as the large unit of measurement e.g.: t.

The relationship between the unit of measurement and the large unit of
measurement is determined with a factor e.g. 1000. The large unit of measure is
advantageous when defining quantities that refer to a longer period of time, e.g.
belt quantities per hour.

5.2.38 DR 3 – Length unit

The length unit is used for defining the belt length. Calculating the belt load refers
to this definition.

5.2.39 DR 3 – Conversion factor

The conversion factor defines which conversion is to be used between the weight
unit and the large weight unit.
Example:
Weight unit: kg
Large weight unit: t
Conversion factor 1000,0

5.2.40 DR 3 – Determination time

With a static scale (determination time = 0), the operation are executed
immediately after activating the instruction during the adjustment. Zero setting is
also executed immediately when defining a stable weight.
In continuously running scales, e.g. belt scales, a determination time can be
defined for this instruction. The scale runs the determination of the operation point
during the defined determination time as an average value of all measurements
and the average value is output after the determination time has elapsed.
The determination time applies for the following instructions: zero point valid,
adjustment weight 1...4 valid, zero setting, taring.

Example:
Determination time 10 000 ms.
Command: Zeroing

After the determination time is elapsed the average new “zero value” will be
calculated.

Weighing Functions

5.4.3 DR 5 – Pulse constant

The pulse constant of the speed sensor indicates the number of pulses per LU
(length unit) of the belt. SIWAREX FTC calculates the current belt speed on this
basis.

5.4.4 DR 5 – Constant belt speed

Constant speed must be defined if no speed sensor is connected. The calculation

of the flow-rate is then performed using this value.
When a speed sensor is connected, the value must be set to 0.

5.4.5 DR 5 – Minimum belt speed

Minimum belt speed is a limit value for minimum belt speed in % of the nominal

has been undercut, SIWAREX FTC sets a status bit.

5.4.13 DR 5 – Maximum flow-rate

Maximum flow-rate is a limit value for maximum flow-rates in % of the nominal flow-
rate. The entry of the number e.g. 1020 corresponds with 102.0 %. After this value
has been exceeded, SIWAREX FTC sets a status bit.

5.4.14 DR 5 – Minimum belt loading

Minimum belt loading is a limit value for minimum belt loading in % of the nominal
belt loading. The entry of the number e.g. 800 corresponds with 80.0 %. After this
value has been undercut, SIWAREX FTC sets a status bit. In batch mode the
totalizing will be completed after the dosing signal is switched off and the belt
loadin is less than this limit value.

5.4.15 DR 5 – Maximum belt loading

Maximum belt loading is a limit value for maximum belt loading in % of the nominal

After this value has been exceeded, SIWAREX FTC will not execute the zero
setting instruction.

5.4.17 Minimum belt loading for totalizing

Minimum belt loading for totalizing is a limit value for minimum belt loading in % of
the nominal belt loading. Entering the number e.g. 20 corresponds with 2.0 %.

Table 5-3 Allocation of the DR 7

5.5.1 DR 7 – Source for the weight simulation

Instead of the actual weight determination, a weight simulation can be activated for
test purposes. The simulated weight value can be defined through the SIMATIC
interface or through the RS232 interface (SIWATOOL FTC). The weight simulation
makes commissioning a scale much easier in certain situations.

5.5.2 DR 7 – Decade for rounding the decimal places for the process values

This parameter can be used to define to how many decimal places that the
(weight) process values should be rounded. This entry decouples the display of
weight values which trigger the restrictions of the calibration requirements and the
values that are used in the control software.

5.5.3 DR 7 – Force in service operation

After activating this function, the digital outputs can be forced independent of their
parameter definitions. Force control is only possible in service operation and only
with the SIMATIC interface.

!
Warning notice

SIWAREX FTC 5-57

 Before using this function, you must ensure that the system will not reach any
hazardous status caused by the forced control of the digital outputs of the
SIWAREX FTC.

5.5.4 DR 7 – Process value 1 for fast output to the SIMATIC CPU

The current process values can be read as data packages (data records in the
SIMATIC CPU using function block FB43. Transferring a large data record can last
for several CPU cycles and puts a load on system performance.
If a process value should be transferred very quickly to the SIMATIC CPU
immediately after its origination in the SIWAREX FTC, the peripheral interface of
the SIWAREX FTC exists. The data is read by the FB43 cyclically and provided for
the user as an output variable. In the belt scale operating mode, normally the
current belt load (selection code 45) is of some importance.
The selection is made from the following list Table 5-20 Process values for
allocating log fields.

5.5.5 DR 7 – Process value 2 for fast output to the SIMATIC CPU

Process value 2 can be defined just the same as process value 1 (see above).
Normally the current Conti status (selection code 30) is of interest in the belt scale
operating mode.

5.5.6 DR 7 – Definition of the process alarm s 0, 1, 2, 3, 4, 5, 6, 7

The process alarms can be defined with this parameter. The module group can
generate process alarms in the SIMATIC CPU. The control program can react
immediately to an event this way. Defining a process alarm is explained with the
example of process alarm 0. The explanation applies for process alarms 1 to 7 as
well.
If parameter value 0 is defined for process alarm 0 then no process alarms are
generated.
By entering a value unequal to zero, a process alarm is allocated according to the
following procedures:
Value range 1 to 255
Number of the technology message. If the defined technology error occurs then
process alarm 0 is generated.
Value range 256 to 319
Number of the bit from the NAWI- or Conti status (see DR 30). If the defined status
occurs then process alarm 0 is generated.
256+ 0... 31 Bit-No. NAWI status bit coming
288+ 0... 31 Bit-No. Conti status bit coming
Value range 512 to 575
Number of the bit from the NAWI- or Conti status (see DR 30). If the defined status
goes then process alarm 0 is generated.

5.5.7 DR 7 – S7-FB-Life bit monitoring time

The SIWAREX FTC can determine whether the FB is maintaining the

communication with the SIMATIC CPU by monitoring the life bit. If the FB does not
respond, an operating error is output after the defined time has elapsed. Monitoring
is active in RUN status of the SIMATIC_CPU.

5.5.8 DR 7 – Weight for the zero point (0 or 4 mA)

A weight for the range start can be defined when defining the range parameters for
the analog output.

5.5.9 DR 7 – Weight for the end value (20 mA)

When defining the parameters for the range for the analog output, a weight can be
defined for the range end.

5.5.10 DR 7 – Replacement value for the analog output with OD

A weight can be defined for the analog output, for which a corresponding signal is
output if the OD signal (Output Disable) exists.
Normally this corresponds with the SIMATIC CPU status – STOP.

5.5.11 DR 7 – Source for the analog output

The source for the analog output can be defined with this parameter. The weight
values from the defined source are output as current signals corresponding with
the parameter definitions for start and end ranges.
The following sources are available:

0 – Control value from the SIMATIC (FB)

1 – Default value from the DR 17
2 – Gross weight
3 – Net weight
4 – Belt speed
5 – Flowrate
6 – Belt load

5.5.14 DR 7 – RS232- transmission control for printer

The transfer control parameters for the RS232 interfaces can be defined as
follows:

XON/XOFF (for printer protocol only)

0: XON/XOFF transmission control OFF
1: XON/XOFF transmission control ON

RTS/CTS (for printer protocol only)

0: CTS/RTS transmission control OFF
1: CTS/RTS transmission control ON

5.5.15 DR 7 – Protocol selection for RS 485

The following protocols can be set for the RS485 interface

- No protocol
- Protocol for the S102 display from Siebert

5.5.16 DR 7 – Decimal place for the remote display

If a display from the Siebert company is connected to the RS 485 interface, the
decimal place for the display of non-verifiable process values can be defined.

5.5.17 DR 7 – RS 485-Baudrate

The following protocols can be set for the RS485 interface:

5.5.19 DR 7 – Definition of the digital outputs 1, 2, 3, 4, 5, 6, 7, 8

The definition of the digital outputs can be defined with this parameter. Assigning a
bit from the pool of status bits for the scale causes the output to be active (active
can be signal level 0 or 1 – see below) if the bit is set.

When assigning a number between 0 and 63, the digital output is assigned to a
status bit of the scale and when assigning a number > 63, the output remains
inactive.

Value range 42h – FEh not allowed

5.5.20 DR 7 – Level definition for digital outputs 1 to 8

After assigning the definitions for digital outputs to a status bit, the signal that the
output should have when it is active can be determined.
E.g. Digital output 1 (DO1) is determined with bit 0:

SIWAREX FTC 5-61

 If bit 0 is 0 then DO1 is high active and if bit 0 is 1 then DO1 is low active,
If bit 1 is 0 then DO2 is high active and if bit 1 is 1 then DO2 is low active,
etc.

5.5.21 DR 7 – Replacement values for DA 1 to 8 with fault or Output Disable

Normally, the outputs are reset with a STOP of the SIMATIC CPU. This behavior
corresponds with the default settings.
If it makes sense to set an output with a SIMATIC CPU STOP, you can define it
with this parameter.
E.g. Digital output 1 (DO1) is determined with bit 0:
If bit 0 is 0 then DO1 is also 0 with OD signal.
If bit 0 is 1 then DO1 is 1 with OD signal.

The digital output 1 (DO2) is determined with bit 1:

If bit 1 is 0 then DO2 is also 0 with OD signal.
If bit 1 is 1 then DO2 is 1 with OD signal.
etc.

!
Warning notice
If an output is to be set with the SIMATIC CPU STOP then you must ensure that it
does not lead to a hazardous situation.

5.5.22 DR 7 – Replacement value for digital outputs upon operating error

Normally, the outputs are reset with a module fault (operating error). This behavior
corresponds with the default settings.
If it makes sense to set an output with a fault, you can define it with this parameter.
E.g. Digital output 1 (DO1) is determined with bit 0:
If bit 0 is 0 then DO1 is also 0 with fault.
If bit 0 is 1 then DO1 is 1 with fault.

The digital output 1 (DO2) is determined with bit 1:

If bit 1 is 0 then DO2 is also 0 with fault.
If bit 1 is 1 then DO2 is 1 with fault.

If an output is to be set with the fault (operating error) then you must ensure that it
does not lead to a hazardous situation.

5.5.23 DR 7 – Definition of the digital input s 1, 2, 3, 4, 5, 6, 7

The definition of the digital inputs can be defined with this parameter. This can
happen by allocating an instruction.
Commands:
If the signal 1 appears at the defined input then the assigned command is
executed. To allocate an instruction to an input, its instruction number (1 to 255)
must be entered (see Command list). By entering 0, the input is assigned as
unused.

5.5.24 DR 7 – Level definition for digital inputs 1 to 7

After assigning the definition for digital inputs to a command or a step-on condition,
you can define which signal that the should be interpreted as active on the input.
E.g. Digital input 1 (DI1) is determined with bit 0:
If bit 0 is 0 then DI1 is high active and if bit 0 is 1 then DI1 is low active,
If bit 1 is 0 then DI2 is high active and if bit 1 is 1 then DI2 is low active,
etc.

5.5.25 DR 7 – MMC log overflow, MMC Trace overflow, Target memory for trace function

Bit 0 is used for defining how the logging should be performed in the verifiable
MMC memory when the memory is full.
0: with full memory, the logging procedure is stopped
1: with full memory, the oldest entries are overwritten

Bit 1 is used for defining how the logging of trace data should continue if memory is
full.
0: No overwriting of trace data is possible with full MMC memory
1: The oldest trace data is overwritten with full MMC memory
The description of the trace function is found in 5.5.28

Bit 2 defines which memory is used for recording the trace data.

with this parameter.
Up to 100% is permitted in this definition but the total for trace function and
verifiable log may not exceed 100%
The description of the trace function is found in 5.5.28

5.5.28 DR 7 – Trace function recording cycle

Every n-th measurement (n x 10 msec) is recorded. When recording to RAM, n ≥ 1

is possible and when recording to MMC, n ≥ 5 is possible.
The recording can be started with the "Start Recording" 70 command and stopped
with "End recording" 71 command.
A recording element has a length of 46 bytes and contains several measurement
values and status bits (see Table 5-23 Construction of a logging element).
The values that are recorded can be read with the SIWATOOL FTC and can then
be exported into MS EXCEL.
If the trace function is defined as recording into cyclic memory then it can be used
to construct a status recorder. The command for starting the recording can come
from the SIMATIC control program and the command for stopping can also come
from the control program, e.g. if you want to record and save the progress of a
procedure.

The trace function is used for logging measurement values and current states of
the scale in RAM memory of the SIWAREX FTC or in the MMC card.
When logging to RAM, SIWATOOL FTC reads the trace elements with data record
120 and when logging to the MMC it is done through data record 121.
Logging is started with instruction "Start recording" 70 and can be ended with the
instruction "End running recording" 71.

Table 5-23 Construction of a logging element

The evaluation of the collected data can be handled using SIWATOOL FTC and
MS Excel. All of the logged elements that have been recorded are stored in the
Excel table and can be read in a graph over time.
The progress of the weighing procedure can be analyzed and optimized.
In the event of sporadic events in the system, the recording can be activated as
circulating memory and can be ended with a condition in the SIMATIC control
program at any time. The subsequent evaluation can help to explain a sporadic
event in the system. A simultaneous evaluation of the message buffer, in which the
last 100 events are stored (evaluation with SIWATOOL FTC) offers a good basis
for an analysis or remote analysis.
An element requires 46 bytes. If the recording is run e.g. once per 50 msec, it
means memory requirements of 920 bytes per second.
In the simplest case, the RAM memory (approx. 2 MB) of the SIWAREX FTC can
be used for the recording.

Commands

6 Commands

6.1 Command groups

The SIWAREX commands are divided into groups. The combining of the
commands into a group is done according to their functionalities.
Every command has a unique number. A command can be sent via various
interfaces (SIMATIC, SIWATOOL FTC, digital input).
Every time that a command is sent to SIWAREX FTC, a check must be made for
whether the command has been executed correctly. The data and operating errors
(synchronous errors) that are generated provide information on why the command
could not be executed.
The group Service- and adjustment commands is used during the
commissioning of the scale. As long as the scale is not adjusted, it can only be
used in service operation. Switching to service operation is indicated in the status
bits.
The group of Scale commands NAWI contains all commands that affect the
handling of a statistic scale. Normally, commands that have anything to do with the
operation of the SIWAREX FTC as a Non-Automatic Weighing Instrument (e.g.
zero setting, taring).
The extensive group of Belt Scale commands is used for controlling the belt
scale. The basic behaviour of the SIWAREX FTC is defined one time by defining
parameters.
The group of Log commands contains commands that control the log output to a
printer or the calibratable storage of the logs to the MMC.
Use of the Micro Memory Card MMC is controlled with commands from the
command group Micro Memory Commands.
After receiving a command, SIWAREX FTC checks for whether the command can
be executed. If the check results are negative, the user is informed of the cause by
an output of a "synchronous" message (see chapter 7 Messages and
Diagnostics).

Messages and Diagnostics

7 Messages and Diagnostics

7.1 Message types

The SIWAREX FTC messages are divided into different types.

Asynchronous messages can be generated at any time by an unpredictable

event. The internal and external hardware faults (operating messages) and the
technology messages that can occur spontaneously during a weighing procedure.

Synchronous messages are always the response to user activity.

There are data errors if a plausibility error is determined in a data package that the
user wants to send to the module and the module does not accept that data
package. These are also command errors if the module in the current operating
status cannot execute the given command.

The status displays are not messages in this respect. The status display
describes the status of the scale in normal operation and can be monitored or
evaluated at any time.

7.2 Message paths

The SIWAREX FTC messages are passed on to the user by various paths. During
project planning, it is important to choose the right path for routing and processing
the messages.

Basically, the messages are processed for two purposes:

• For display on an operating panel
• For connection to control software to control certain reactions in a process.

SIWAREX FTC 7-93

 The following message paths are possible:

• Message buffer output to the SIWATOOL FTC commissioning program

• Output through the SIWA_FTC function block to its message outputs
• Diagnostics alarms in SIMATIC CPU with OB82 evaluation
• Process alarms in the SIMATIC CPU with evaluation in the process alarm
OBs.

7.3 Recognising messages using SIWATOOL FTC

A message buffer is integrated in the module and holds up to 100 entries. If the
number of messages in the message buffer reaches 100 then a new message will
immediately delete the oldest message. The message buffer can be read at any
time with SIWATOOL FTC (menu point "Read all data records") and can be saved
together with the scale parameters. This helps in recognising, analysing and
solving problems in the system.

7.4 Recognising messages using the FB SIWA_FTC

All of the messages of the SIWAREX module can be recognised and processed in
the controller using the FB SIWA_FTC. Additional errors in the processing of the
FB SWIA_FTC are put out through the FB_ERR output variable (see chapter 8
Programming in SIMATIC STEP 7.)

7.5 Recognising messages using the diagnostic alarms in the SIMATIC-

CPU

Operating messages (hardware faults) are recognised in the SIMATIC CPU with
diagnostic alarms. For more information, see chapter 8 Programming in SIMATIC
STEP 7.

Recognising messages with process alarms.

Process alarms enable the user to respond flexibly to technology messages or to

the corresponding status information. For more information, see chapter 8
Programming in SIMATIC STEP 7.

8.1 General Information

SIWAREX FTC was developed specifically for operation with the SIMATIC S7.
The hardware construction is described in detail in chapter 4. SIWAREX FTC is
projected as a function module in the SIMATIC manager. In order for the
SIWAREX FTC to be accepted into the module assembly catalogue of the
SIMATIC manager, the SETUP program (SETUP_FOR_SIMATIC on the project
planning package CD) must be executed.
A project is delivered with the standard software that is required for the operation
with the SIWAREX FTC and is included with the project planning package.
Example program SIWAREX FTC "Getting started” are also available on the
Internet. It shows how application software can be created and how simply
messages can be generated.
Using SIWAREX FTC "Getting started” and creating your own supplements for
various applications is recommended e.g. using the message block for
SIWAREX FTC since the processing and displaying of errors exhibited by
SIWAREX is performed very simply.

8.2 SIWAREX FTC in the HW Configuration

During project planning for the hardware configuration in the SIMATIC manager,
the basic properties of the module are defined:
- The peripheral address of the module
- Diagnostic alarm enable
- Process alarm enable
- Behaviour for CPU stop

SIWAREX FTC requires 16 bytes in the input and output areas.

Other scale specific parameters that are also changed during the control program
run-time can be defined in two different ways:
- Using the SIWATOOL FTC parameter definition tool
- By defining the parameters in a scale data block and then transferring them to
the SIWAREX FTC. Cyclic communication between the SIWAREX FTC
module and the SIMATIC CPU is established through the FB SIWA_FTC
function block (FB44).

Programming in SIMATIC STEP 7

8.3 SIWAREX FTC in cyclic STEP 7 – Program

SIWAREX FTC communicates with the SIMATIC CPU with the function block FB
SIWA_FTC. While programming the call, an instance data block is created for the
FB SIWA_FTC. Besides the instance data block, a scale DB is required for every
Scale SIWAREX FTC, in which the scale parameters are stored. The UDT that
comes with it can also be used for creating the scale DB.
The vector DB must also be loaded in the SIMATIC CPU. A vector DB can be
used by more than one SIWAREX FTC.
The function block FB SIWA_FTC and the data block are found on the CD for the
project planning package SIWAREX FTC for SIMATIC S7 in the S7_Software
directory.
The function block FB SIWA_FTC is called one time for each scale in the
application program cyclically in a program level (e.g. in OB1) and provided with
call parameters.

8.4 Call parameters for FB SIWA_FTC

The call parameters of the FB SIWA_FTC are described in the following section.
The call parameters are defined as variables in the scales DB when delivered. It is
possible to define the call parameters with other variables of the same type.
While calling the FB SIWA_FTC, the number of the instance DB to be generated
must be defined.

SIWAREX FTC 7-105

8.4.1 ADDR:= 256, Input, INT

SIWAREX FTC requires 16 bytes in the input and output range of the SIMATIC
CPU for operation. The ADDR parameter must correspond wit the definition in the
HW configuration.

8.4.2 DB_SCALE:= 15, Input, INT

A scale DB must be defined for every scale, in which the parameter of the
SIWAREX FTC and the current actual value are found. The number of the DB can
be selected as desired. DB15 has been defined as the scale DB in the project
planning package. In addition, the UDT15 is also provided as a template for
creating block modules.

8.4.3 DB_VECTOR:= 14, Input, INT

The content of the vector DB may not be modified by the user. It must be loaded
one time only per SIMATIC CPU, independent of the number of SIWAREX FTC
modules that are used. The number of the DB can be selected as desired.

8.4.4 CMD_IN:= "DB_SCALE".i_CMD_INPUT, Input, INT

The user controls all command using this input variable, whether for transferring a
data record or executing a weighing task. The commands are described in chapter
6. The user prepares the command number using this variable and triggers the
command using variable CMD_EN:= "DB_SCALE".bo_CMD_ENABLE (see
chapter 8.4.22). The FB SIWA_FTC does not delete the command number, it
resets the trigger variable CMD_EN:= "DB_SCALE".bo_CMD_ENABLE after the
command is finished.

8.4.5 SIM_VAL:= "DB_SCALE".r_SIM_VALUE, Input, REAL

If the simulation has been enabled (see chapter 5.5.1), the value to be simulated
can be defined on this input. The value should be found in the weighing range of
the weighing instrument.

8.4.6 ANA_OUT:= "DB_SCALE".r_ANALOG_OUT_VALUE, Input, REAL

If control of the analog outputs has been enabled (see chapter 5.5.11), the value to
be controlled can be defined on this input. The value should be found in the
defined range of the weighing instrument.

8.4.7 DO_FORCE:= "DB_SCALE".b_DIG_OUTPUT_FORCE, Input, BYTE

If forced control of the digital outputs has been enabled (see chapter 5.5.3), the
value to be controlled can be defined on this input. Bit 0 corresponds with digital
output 0, bit 1 corresponds with digital output 1, etc.

8.4.8 CMD_INPR:= "DB_SCALE".bo_CMD_IN_PROGRESS, Output, BOOL

This bit informs the user that a command is being processed at the moment.

This bit informs the user that a command has been executed successfully
(Command complete without errors).

8.4.10 CMD_ERR:= "DB_SCALE".bo_CMD_ERR, Output, BOOL

This bit informs the user that a command has not been executed. The bit is set for
one cycle (edge) only. The cause can be evaluated in the same cycle with variable
CMD_ERR_C:= "DB_SCALE".b_CMD_ERR_CODE. The number is decoded in
the table "Data and Operating Errors" in chapter 7.6. If no error code is defined, the
error must be evaluated in "DB_SCALE".b_FB_ERR_CODE.

8.4.11 CMD_ERR_C:= "DB_SCALE".b_CMD_ERR_CODE, Output, BYTE

If a command is not executed (completed with error) the error code number is
output here. The number that is output is decoded in the table "Data and Operating
Errors" in chapter 7.6. The value remains in the output until the next command is
triggered. The evaluation is to be performed when the set bit CMD_ERR:=
"DB_SCALE".bo_CMD_ERR appears. If an error code is defined, the error must be
evaluated in "DB_SCALE".b_FB_ERR_CODE.

8.4.12 REF_COUNT:= "DB_SCALE".b_INFO_REFRESH_COUNT, Output, BYTE

The current output values which are prepared as output variables of the FB
SIWA_FTC are read cyclically by the FB through the peripheral range. SIWAREX
FTC updates the values internally in a 10 msec rhythm. Every update is assigned a
number which can be used in the SIMATIC CPU like a time stamp.

8.4.13 PROC_VAL1:= "DB_SCALE".r_PROCESS_VALUE1, Output, REAL

The selected process value can be output using this variable (See chapter 5.5.4).
The gross weight or the net weight of the scale is normally output here.

8.4.14 PROC_VAL2:= "DB_SCALE".w_PROCESS_VALUE2, Output, DWORD

The selected process value is output using this variable (See chapter 5.5.5). The
status of the automatic weighing instrument AWI (see chapter 5.14.2 ) is normally
output here.

8.4.15 SC_STATUS:= "DB_SCALE".dw_SCALE_STATUS, Output, DWORD

The status of the non-automatic weighing instrument NAWI (see chapter 5.14.1) is
always output through this variable.

8.4.16 ERR_MSG:= "DB_SCALE".bo_ERR_MSG, Output, BOOL

All messages that are prepared by SIWAREX FTC are prepared in an output buffer
on the module. If a new message appears, this bit is set. The user can evaluate the
meaning using variables RR_MSG_TYPE:= "DB_SCALE".b_ERR_MSG_TYPE
and ERR_MSG_C:= "DB_SCALE".b_ERR_MSG_CODE. After the message is

SIWAREX FTC 7-107

 acknowledged by the user (ERR_MSG_Q:= "DB_SCALE".bo_ERR_MSG_QUIT),
the bit is reset by the function block.

8.4.17 ERR_MSG_TYPE:= "DB_SCALE".b_ERR_MSG_TYPE, Output, BYTE

The user is shown which message is there with variable:

Bit 0 – Operating message (Fault)
Bit 1 – Technology error
Bit 2 – Data or operating error

8.4.18 ERR_MSG_C:= "DB_SCALE".b_ERR_MSG_CODE, Output, BYTE

The user is informed of the message number with this variable (suitable for
ERR_MSG_TYPE:= "DB_SCALE".b_ERR_MSG_TYPE). After the evaluation of
the message, the user indicates to the FB that the message has been evaluated
(with variable ERR_MSG_Q:= "DB_SCALE".bo_ERR_MSG_QUIT) and the FB
SIWA_FTC is ready to output the next message if one exists.

8.4.19 FB_ERR:= "DB_SCALE".bo_FB_ERR, Output, BOOL

If an error has occurred during the processing of the function block itself, it is
indicated through this variable.

!
Warning
If a processing error occurs for FB SIWA_FTC, we have to assume that the
variables that have been output do not correspond with the actual status in the
module.

8.4.20 FB_ERR_C:= "DB_SCALE".b_FB_ERR_CODE

The error number of the FB SIWA_FTC is output through this variable.

The following messages can be output:

Bit 0 – DB_SCALE or DB_VECTOR are missing or have incorrect lengths

Bit 1 – Error with internal call for SFC58 or SFC59, the value RET_VAL is entered
in DW4 for one cycle in the scale DB
Bit 2 – Error interpreting a data record / command, defined data record or

Warning
If a processing error occurs for FB SIWA_FTC, we have to assume that the
variables that have been output do not correspond with the actual status in the
module.

8.4.21 START_UP:= "DB_SCALE".bo_START_UP_IN_PROGRESS

Communication between the SIWAREX FTC and the FB SIWA_FTC is

synchronised when the SIWAREX FTC module is restarted (normally when the
SIMATIC CPU is started). The bit can be output for more than one cycle.

8.4.22 CMD_EN:= "DB_SCALE".bo_CMD_ENABLE

After entering the command number in the CMD_IN:= "DB_SCALE".i_CMD_INPUT

variable, the execution of the command is triggered with this bit. To prevent the
command from being triggered more than one time, the bit should be created as an
edge. The FB SIWA_FTC does not delete the command number, it resets the
trigger variable CMD_EN:= "DB_SCALE".bo_CMD_ENABLE after the command is
finished.

8.4.23 ERR_MSG_Q:= "DB_SCALE".bo_ERR_MSG_QUIT

After evaluating a message with variable ERR_MSG_C:=

"DB_SCALE".b_ERR_MSG_CODE the user acknowledges this message.
FB SIWA_FTC can then output the next message.

8.5 Allocation in the Scale DB

The contents of the scale DB are data of data records witch are available for
SIMATIC-CPU. All components of the SIMATIC STEP7 software for SIWAREX
FTC are in the English language.

8.6 Calibratable weight display on OP/TP/MP 170B, 270, 370

For displaying the calibratable weight value, the same device that the operator
uses for running the system can be used.

SIWAREX FTC 7-109

 The calibratable main display for one or more scales can be one of the following
devices:
TP170B, OP170B
TP270, OP270, MP270B
MP370
The SIMATIC HMI device can be connected with the MPI or to PROFIBUS. The
calibratable display of the weight value can be connected to any position in the
system hierarchy. The connection does not have to be sealed and future planning
for operator windows are also not influenced by the calibratable weight display.

8.6.1 Functionality of the calibratable weight display

The value for the calibratable weight display is generated internally by the
SIWAREX FTC, it is encoded and then provided in the data record DR 35 for the
user. The DR 35 data record is read by the FB SIWA_FTC and is put in the scale
DB just like every other data record in a defined address. The content of the DR 35
can be sent through bus connections to other SIMATIC CPUs or can be evaluated
locally.
An AddOn for ProTool is used for evaluating – a special function which is in the
position to decode the contents of the DR 35 and to display it in a special output
field. This AddOn is called "Secured output" and must be installed separately to
ProTool.

Image 8-2 Calibratable display in TP/OP

8.6.2 Installation and Project Planning for the Calibratable Weight Display

First, the OCX must be linked into the project planning environment of ProTool for
the secured output. This is possible with version 6.0 SP2 ProTool(Pro) or higher.
The setup.bat program which can be used for performing the installation is found in
the OCX_DISPLAY directory of the project planning package.
If the ProTool is not on drive C: or D: then the setup.bat program must be edited in
an editor and rewritten to correspond with the drive that it is on.
After executing the setup.bat program, the Prootool.ini file must be changed
according to the note in setup.bat.

Programming in SIMATIC STEP 7

Image 8-3 "Secure output" function in ProTool

If ProTool is called again afterwards, a new function appears in the tool-bar (see
arrow) – "Secure output", which is projected just as all other functions.
During planning, the address of the data record DR 35 must be defined. The
variable is BYTE and has a length of 32 bytes.
The refresh rate lies somewhere around 200 to 300 msec which is comfortable to
the eye.
Note
After converting a project to another target device, the secured output must be
deleted in the images and projected again.

SIWAREX FTC 7-111

 Note
When loading the project to the target device, a notice can be displayed which
indicates that the OCX is not certified. This notice has no influence on the
functionality of the AddOn.

9.1 General Information

The integration of SIWAREX FTC is possible as of PCS 7 version 6.0.

In the first step, SIWAREX FTC must be added to the hardware catalogue by
running the SETUP_FOR_SIMATIC_S7.
While planning the hardware configuration in the SIMATIC Manager, the basic
features of the module are defined:
- The peripheral address of the module
- Enabling the diagnostic alarms
- Enabling the process alarms
- Behaviour in the case of a CPU-Stop

SIWAREX FTC takes 16 bytes in the input and output area.

Other scale specific parameters that are also changed while the control program is
running can be defined in three different ways.
- Using the SIWATOOL FTC parameter definition tool
- Internally by making the definition in FB641 and then transferring to SIWAREX
FTC
- In the OS using the Faceplate.

The provided example – Faceplate can be expanded or modified using the

Faceplate Designer.

Here first the SIWAREX FB is described , then the Face Plate from the operator's
viewpoint and finally there are notes on project planning with the Faceplate.

SIWAREX FTC 9-113

9.2 FB for SIWAREX FTC

9.2.1 FB643 for CFC

The SFT_FTC function block is integrated into an interrupt alarm-OB e.g. OB32.
The block must also be integrated in the following OBs in the run sequence (done
automatically in CFC):

OB82 Diagnostics alarm

OB100 New start
After starting up, the module identification for the installed module is read in order
to determine parameter errors. The messages remain blocked for the number of
cycles that have been defined in the parameters on input RUNUPCYC.

9.2.2 Function and Functionality

The block is used for controlling a SIWAREX FTC module group. Data is
transferred cyclically through the peripheral interface and the various data records
are read from the modules or transferred to the modules acyclically. The message
queue of the modules is read continuously and respective WinCC messages are
generated.

Note:
In the definition of the S7 interface in DR7, the values for PROCESS_VALUE_1
(5.5.4) and PROCESS_VALUE_2 (5.5.5) must be assigned as follows:
PROCESS_VALUE_1 = 2 (Flow 1)
PROCESS_VALUE_2 = 30 (Conti Status)

9.2.3 Addressing and Driver Wizard

The IO addresses for the SIWAREX FTC modules must be completely within the
process image of the CPU. The LADDR input has to be connected with the base
address of the SIWAREX FTC modules. Procedures:
Select input -> right mouse key -> switch to operand ... -> entry of e. g. EW512.
The PCS7 driver wizard then automatically creates all required driver blocks. The
Function block inputs MODF, PERAF and RACKF are automaticly connected by
the driver wizard, the inputs SUBN1_ID, SUBN2_ID, RACK_NO, SLOT_NO,
BASADR and DADDR are automaticly defined according to the data in the HW
configuration.

9-114 SIWAREX FTC

Project planning in SIMATIC PCS 7

9.2.4 Manual/Automatic

Switching between the two operating modes is either done using the OS
operations via AUT_ON_OP (LIOP_SEL = 0) or by switching the input AUT_L
(LIOP_SEL = 1). When selecting with the OS system, the corresponding
AUTOP_EN and MANOP_EN enables are required. The defined operating mode is
displayed on output QMAN_AUT (1: Auto, 0: Manual).

Manual operation: The commands are sent from the operator to the module
through input MAN_CMD. Each change in the command code on this input is
recognized as a new command. The source of data records to be sent to the
modules are the manual inputs (extension ‘_M’).

Automatic operation: The function block takes its commands on a positive edge
on input AUTCMDEN from the switchable AUT_CMD input.
The source of data records to be sent to the modules are – as long as they exist –
the automatic inputs (extension ‘_A’), and otherwise the manual inputs (extension
‘_M’).
A command sequence (e.g. read all data records) will only be interrupted by a new
command code after the current command is completely executed.

Image 9-1 SFT_FTC function block in CFC

9.2.5 Data records

All data records that the S7 controller can access exist as individual parameters of
the function block. The parameters of the data blocks that can be read have the
extension ‘_O’ for Output. The parameters of the data blocks that can be written to
have the extension ‘_M’ for Manual and are transferred to WinCC for visualization.

SIWAREX FTC 9-115

 If no automatic inputs exist for a data records then the values of the manual inputs
are transferred to the modules in automatic operation. In certain cases, the manual
inputs can be switched in the AS program but then they can no longer be used in
WinCC.

9.2.6 Commands

The commands can also be taken from the command list.

9.2.7 Module error messages

The error message buffer on the SIWAREX FTC module group is read
continuously by the block. If a message is read then the ERR_MSG output is set to
"TRUE” for one cycle. Outputs ERR_MSG_TYPE and ERR_MSG_C contain the
type of error and the error code of the respective message.

ERR_MSG_TYPE Meaning
16#01 Operating messages (Fault)
16#02 Technological fault
16#04 Data or Operating Error
sent in addition with operating message
16#80
(fault).
Table 9-1 CFC – Message types

The meaning of the error number codes can be found in the message lists.

9-116 SIWAREX FTC

Project planning in SIMATIC PCS 7

Corresponding with the type of error, WinCC sets messages with text,
technological error, data/operating error, internal or external error with the error
code attached. These messages always have either a received or sent status. The
error code of the last read error message is always present. The most important
operating error messages are generated individually.

9.3 Examples for image blocks for SIWAREX FTC

9.3.1 Faceplate display in OS

The example faceplate for the SIWAREX FTC modules was created with the
Faceplate Designer from PCS7 version 6.0. The WinCC images and scripts that
are created can be modified according to individual requirements.
The Faceplate should be called with the dynamic wizard “Picture selection via
measurement point”. The example faceplate includes the following views:

Image 9-2 Standard view for SIWAREX FTC

9-136 SIWAREX FTC

Project planning in SIMATIC PCS 7

Here the operator can view the current Flow of the scale and some selected status
bits. The Manual/Automatic operating modes can also be switched.

Image 9-3 Service view, tab Calibration 1/2

In this view the operator can view and change important calibration data. Pressing
the button “Send Data” or “Receive Data” will send and receive the hole data
record 3 respectively, also the data that are not shown in these views.

Image 9-4 Service view, tab Belt Scale

SIWAREX FTC 9-137

 Here the operator can view and change the important data for the basic setting of
the belt scale. Pressing the button “Send Data” or “Receive Data” will send and
receive the hole data record 5 respectively, also the data that are not shown in
these views.

Image 9-5 Service view, tab Commands

Here the operator can execute all important commands for calibration and
operation of the belt scale further on he can watch selected important status
information. !! Pressing the button “Send Data” or “Receive Data” will send and
receive the all data records of the Siwarex FTC respectively.!!

Image 9-6 Dosing view, tab Sum 1/2

In this view the operator can watch, delete- and delete and protocol all the
totalizers. Deleting means that the totalizer left hand to the button will be set to
zero. “Delete and Prot.” Means that the toalizer will be printed with log text 1 (The

9-138 SIWAREX FTC

Project planning in SIMATIC PCS 7

totalizer has to be in log text 1) and after that set to zero. The button “Delete all”
will cause a set to zero of all totalizers, in tab “Sum 1” and “Sum 2”. The “Actualize”
button will read the data record 33 one time, all totalizers will be updated, only after
pressing this button the display will be updated.

Image 9-7 Dosing view, tab Operation

In this view the operator can watch the flow value and activate all important
command for the belt control, totalizing and dosing.

9.3.2 Faceplate Creation

Mainly, those standard items that are described in the documentation on the
Faceplate Designer and that have been delivered with the Faceplate Designer are
used. This description concentrates on the features that have been implemented
for the SIWAREX FTC Faceplate.

Tabs
To help clarify matters, two Faceplate view with up to 4 tabs have been shown in
different images. Switching between the tabs is done using function
"SH6_ChangeView_tab.fct". Each tab must have the name of the image that it is
calling.

Operating authorization
In every view, an element with the name "Level5_MODE" or "Level6_MODE" is
found. These elements do not only the enable operating authorization from the
User Administrator but they also deny operating authorization in Automatic
operating mode. This is done with function "SH6_CheckPermission_Plus.fct",
which is called when the image is loaded and when the operating mode is
changed. Passing the operating mode to the individual elements is performed
through direct connections.

SIWAREX FTC 9-139

 Only the Manual-Automatic switch with the "single operating authorization" (level5)
can be used with the default settings. All other operations require the "higher value
operating authorization" (level6).

Combo-boxes with several entries

Various combo-boxes have 3 or more entries. These combo-boxes are described
further using an example of the combo-box for the dosing commands.
With a mouse click on the combo-box, the image
"@PG_SFT_FTC_SCROLL_WEIGHING.pdl" is opened:

Image 9-8 Combo-box with several entries

The image "@PG_SFT_FTC_SCROLL_WEIGHING.pdl" is based on the

"@FPD_BedAnalog.PDL" image. The main difference is that the analog value is
not entered in the IO-field, instead, a command which has an analog value
assigned as the command code is selected. The commands are listed in individual
text fields in the image “@PG_SFT_FTC_CMD_SERVICE.pdl“:

Image 9-9 Command selection

While selecting a command with the mouse, the command code is written into the
IO-field "Value" of the "@PG_SFT_FTC_SCROLL_WEIGHING.pdl" image. If the

9-140 SIWAREX FTC

Project planning in SIMATIC PCS 7

output value "Value" is changed then the transmitted command is highlighted in

colour and the respective command code is transferred to the block with "OK".

Faceplate Views
In all Faceplate views, the invisible objects in the WinCC runtime are also
displayed. The switching of the individual elements can also be handled in the
WinCC images.

10 Commissioning using a PC – SIWATOOL FTC

10.1 General
The scale can be put into operation using the SIWAREX FTC program
independent of commissioning the SIMATIC automation system.

The program is included with the delivery of the project planning package.
The program (Catalogue SIWATOOL_FTC) must be installed in the first step.
Memory requirements on the hard disk are less than 30 MB.

10.2 Windows and functions of the SIWATOOL FTC

The program windows are constructed so that navigating through the parameters
of the SIWAREX FTC is made easier. In the left-hand portion, an overview of the
parameters is shown in a tree structure. Grouping the parameters corresponds with
the various activities which can occur during project planning, commissioning,
testing and during service.
A data record in SIWAREX FTC belongs with every branch of the tree structure.
Several parameters are combined in one data record. In the right-hand window, the
parameters of a data record can be edited in index card format.
An information sheet is shown as the first index card. This information sheet
informs the user of which tasks can be edited with the parameters of the selected
data record. Sending, receiving or transferring always involves the entire data
record and not an index card.

10.3 Offline Project Planning

All scale parameters can be edited and stored without the SIWAREX FTC module.
This can decrease the start-up time.
The parameters for several scales can be prepared in the office and only have to
be transferred to the SIWAREX FTC for commissioning.
Data can also be read from one scale in the operation and used for commissioning
other scales.

10-142 SIWAREX FTC

Commissioning using a PC – SIWATOOL FTC

10.4 Online Operation

To switch to online operation, the PC must be connected through the SIWATOOL
cable (see Accessories) with SIWAREX FTC. The COM interface can be set up in
the communications menu.
All parameters can be changed in online operation. A message window shows the
current contents of the message buffer from SIWAREX FTC. The current process
values can be observed in various windows. For testing purposes, all commands
can be sent to the SIWAREX FTC.
For archiving, all data can be read and stored in a file or can be printed.

!
Warning

In online operation, all data in the module can be edited. The changes are not
automatically fed into the respective scales-data records. You, as the user, must
decide whether the data adjustment is necessary and whether it should be
performed or not.

SIWAREX FTC 10-143

10.5 Assistance

After clicking on a data record in the left-hand program window, the "Info" card can
be selected from the right-hand program window. A description on a white area
indicates the affect that the data record has on the scale's behaviour.
After selecting a card, a section of the respective data record is displayed as input
and output fields. Besides the parameter identification, Tool Tips (text is displayed
when the mouse is over the field) help to describe the parameter.

Clicking on the menu point "Help" opens the "SIWAREX FTC" manual. The
Acrobat Reader program must be installed in order to read the manual.

Firmware-Update with SIWATOOL FTC

11 Firmware-Update with SIWATOOL FTC

11.1 Advantages of the Firmware-Update

If you want to utilize the firmware update offer on the SIWAREX internet pages
(www.siwarex.com / Support), you are able to download the latest firmware cost-
free and using the SIWATOOL FTC, you can transfer it to the modules.
The firmware is located in Flash memory. If required, new firmware can be
transferred to the modules.
The new firmware can slightly vary from the earlier version – this is the case if the
data structures of SIWAREX FTC parameters are not changed. In this case,
loading the new firmware does not change the actual data.
If function expansion in the new firmware results in new internal data structures,
new data records or changes within existing data records then the SIWAREX FTC
assigns the parameters with default values after the download. Therefore, the
original parameter status is read using the SIWATOOL FTC ("Communication
menu", "Retrieve all data records") and stored in a file.
Loading the firmware onto the SIWAREX FTC module is performed over several
steps:
1. Switch the SIMATIC CPU to STOP.
2. Log SIWATOOL FTC in (online)
3. Select Firmware Download, set download mode
4. Select Firmware file
5. Activate download mode with the checkmark
6. Start the transfer
The transfer can take up to several minutes.

After the transfer, SIWAREX FTC is restarted. Communication with SIWATOOL

FTC must be reactivated (reset download mode).

SIWAREX FTC 11-145

Image 11-1 Downloading Firmware with SIWATOOL FTC

!
Warning notice
During the firmware download, SIWAREX FTC do not respond to communication
requests from the SIMATIC CPU. The CUP indicates the peripheral access error
and if no respective organization block (OB) is programmed then the CPU can go
to STOP.
Therefore, loading the firmware should only be done when the CPU is in STOP
status.

Calibrating Applications

12 Calibrating Applications

12.1 General Note

Attention
Calibratable scales may only be certified by a calibration expert or qualified
! representative.

Preparations The following preparations must be made by the scale users before the
actual certification by the calibration expert:

Start SIWAREX FTC

• Adjust the scale according to the device manual
• Check all of the points corresponding with (1), (2), (3) and (4).
(1) = European Regulations ER (90/384/EWG) on non-automatic
weighing instruments
(2) = European Standards EN 45 501 for non-automatic weighing
instruments

Calibration sticker The calibration sticker is found in the calibration set which you can get as an
accessory.

Certifying the The certification of the calibrated scale is done by a calibration expert from a
SIWAREX FTC recognised position.

Stamp of approval on After activating the write protection (WRP switch on the front), the calibration
SIWAREX FTC expert attaches the certification stamp and the calibration mark.

12.2 Calibratable main weight display

The calibratable main display for SIWAREX FTC can either be done on a
calibratable S11 display (company Siebert) or with certain standard SIMATIC

SIWAREX FTC 12-147

 OP/TPs (8.6). The application conditions and details can be found in the design
certification for SIWAREX FTC.

12.3 Reading the calibratable logs with SIWATOOL FTC

The weighing log can be created on a calibratable printer or in the calibratable

memory in the optional Micro Memory Card.
The capacity of the MMC should normally be sufficient for recording the scale logs
for a period of 3 months. The MMC can be configured with SIWATOO FTC so that
the data will overwrite older data when the memory is full. This creates a circulating
buffer that conforms with the documentation of the calibration regulations.
A unique log ID is found in every weighing log that is stored. The log ID is very
important because it is also printed out on the non-calibratable delivery note next to
the amounts.
If anyone objects to a fixed delivery because of the delivered amount, the log ID is
used to help find the log – either in a stack of paper logs or on the Micro Memory
Card.
The SIWATOOL FTC is connected with SIWAREX FTC for this reason. After
entering the log ID, the data to be checked is read from the MMC, which is still in
the SIWAREX FTC and is continuously storing the production scale data, and this
data is then displayed.
