 INTRODUCTION
The DAT 400 is a transmitter of weight to be combined with the load cells to detect the weight in every
situation.
The module is easy to install and can be mounted on 35 mm DIN rail.
The display allows easy reading of the weight, the status of the instrument, the setting parameters and
errors.
The 4 keys located below the display allow the operator to perform the functions of ZERO, TARE,
GROSS/NET switching, setting of the setpoints weight, setting and tare both theoretical than real.
The DAT 400 uses the serial port RS232 with ASCII and Modbus RTU protocols for connecting to a PC,
PLC and remote units. In parallel with the RS232, a USB port available.
They are always available 2 programmable weight setpoints and the control of the maximum weight
value reached (peak).
The RS422/RS485 serial output allows you to connect up to 32 addressable devices.

Housing Cable shield Internally connected to protective
earth according to Profibus
specification
For connection to the Profibus Master, use a standard Profibus cable.
The typical impedance of the cable should be between 100 and
130 Ohms (f> 100 kHz). The cable capacity (measured between
conductor and conductor) should be less than 60 pF / m and the
minimum cable cross section should not be less than 0.22 mm2
In a Profibus-DP network, you can use either cable type A to type B
cable, depending on the required performance. The following table
summarizes the features of the cable to be used:
Specification Type A Cable Type B Cable
Impedance from 135 to 165 ohm from 100 to 300 ohm
(f = 3 – 20 MHz) (f > 100 kHz)

DISPLAY
On the 6-digit display, it’s usually shown the scale weight. According to the various programming
procedures, the display is used for programming of the parameters to be stored in the memory, or the
messages that indicate the type of operation being carried out and help therefore the Operator in the
management and programming of the instrument.

LED INDICATORS
Below the display there are 4 LED indicators:
1 State of the logic output 1 (ON = closed contact OFF = open contact)
2 State of the logic output 2 (ON = closed contact OFF = open contact)
NET The displayed value is the net weight
0 IT indicates the condition of stable weight.

Page 11
 USING THE KEYBOARD
The instrument is programmed and controlled through the keyboard which has 4 keys, with double
functions. The selection of one of the key functions is established automatically by the instrument accor-
ding to the operation in progress. In general, the management of the programming menus is done by
using the SET and FUN keys to scroll through the items; the PRG key is used to enter its sub-menu or
programmable parameter, while the 0 button allows you exiting the menu or returning to the top level.

 VIEWING, ZEROING THE WEIGHT AND AUTOTARE
After being calibrated, at the subsequent switches on, the display shows the current weight.

VIEWING THE NET WEIGHT/GROSS WEIGHT

FUN
Press the key to toggle between the net weight and the gross weight and vice versa. The value
displayed is signaled by the LED NET (lit: net weight). If you have not entered the tare, the net weight
is equal to the gross weight.
In case of negative weight, it is displayed the minus sign before the most significant digit.

ZEROING, WEIGHT AND AUTOTARE

These two functions are performed by pressing 0.
When the instrument is in the operation mode “Net” (“NET” LED on), the 0 key performs the AUTOTARE.
When the instrument is in operation mode “Gross” (“NET” LED off), the 0 key clears the gross weight.

AUTOTARE
The execution of AUTOTARE is possible under the following conditions:
• Instrument under conditions of “Net” (NET” LED on).
• Positive gross weight.
• Gross weight not greater than the maximum capacity.
• Stable weight.
• Unstable weight. In this condition, we must distinguish two cases:
1. The weight stability control is enabled (the parameter “MOTION” (*) must be other than zero): the
command executed while the weight is unstable only has an effect if the weight stabilizes within 3
seconds from the moment the command was given.
2. The weight stability control is disabled (the parameter “MOTION” (*) is equal to zero): the executed
command takes effect immediately, even with unstable weight.
(*) The operating modes of the parameter “MOTION” are described on page 28.
The AUTOTARE is retained in memory even after the power is switched off.

ZEROING
The reset command of the gross weight is used to correct for small zero shifts of the weighing system
during normal operation.
Normally these zero shifts are due to thermal drifts or to residues of material that accumulate on the
weighing system over the time.
To run the command, it is necessary that the instrument is under conditions of “Gross” (“NET” LED off)
and that the deviation of the weight with respect to the zero of the scale (the one performed with the
calibration of zero) does not exceed (in positive or negative) the number of divisions set in parameter
“0 BAND” (inside the PARAM menu).
The reset command of the gross weight does not run if there is even one of the following conditions:
• Unstable weight (with control of the stability of the weight enabled). In this case, the reset command
takes effect only if the weight stabilizes within 3 seconds or if the control of the weight stability is
disabled (parameter “MOTION “ equal to zero).

Page 15
• Gross Weight greater (in positive or negative) than the number of divisions set in parameter “0
BAND” , when the setpoint of auto-calibration is not programmed.
The zero obtained with the resetting of the gross weight is retained in memory even after the power is
switched off.
The reset operation of the gross weight can be repeated several times, but the number of reset divisions
zero is added from time to time, so when the total exceeds the limit value set in parameter “0 BAND”,
the zero cannot be executed. In this case, it is necessary to calibrate the Zero.
Any auto-zero parameter setting when switching on (AUTO 0) reduces (or cancels, in the case of “AUTO
0”> “0 BAND”) the range of action of the reset command.

PEAK FUNCTION
The instrument continuously memorizes the peak value of the gross weight. The peak value is detected
at the same frequency of acquisition of the weight (see table on filters). In addition to visualization, the
peak value can be used in the following functions:

FUNCTION DESCRIPTION
The setpoints can be set to have the peak value as a reference. (See the
LOGIC OUTPUT
procedure for setting the logic outputs operations).
Acquisition of the peak value (peak hold) through the CONTIN, AUTO, DE-
SERIAL PORT

 SETTING

GENERAL DATA
All functions of the DAT 400 are activated and modified by accessing a simple setup menu, shown on
page 21. All settings selected or activated remain stored even after switching off the transmitter.
The DAT 400 is preconfigured with a default setting. The following pages show the values of “Default”
for each parameter.
With the first on-site installation, it’s necessary to change some parameters in order to obtain a correct
indication of the displayed weight (Theoretical adjustment).
This may be required when you purchase the DAT 400.
The settings of the setup menu can be changed using the front keys or via the utility “INOVATION 2”
software supplied.

 CONFIGURATION PARAMETERS
Through the setting of the parameters listed below, the theoretical Full Scale DAT 400 calibration is
performed. These steps with the zero calibration described on the next page must be completed. The
procedure ensures a good accuracy of the system (maximum error <1% FS) if there are no mechanical
problems.
Program the known values of total capacity and sensitivity of the load cells and the approximate values
of net capacity and calibration. If the parameter SENSIT is not programmed, it is taken the 2.0000
mV/V value.
If the parameter CAPAC is programmed other than 0, according to the data CAPAC, SENSIT, NET and
DEAD L , the instrument automatically runs the following functions:
Resetting the linearization points.
Selection of the value of the division, however, to be modified, to the best of 10,000 divisions.
Calibration of the theoretical approximate calibration of the weight (zero and full scale).
Automatic programming of the overload setpoint (= NET).
These functions are performed each time you change one of the 4 parameters shown.
When you change the DSPDIV selection., it is automatically recalculated to full-scale calibration. The
selections are incompatible with the calibration parameters or calibration in memory are not accepted.
The selection programmed in Opmode is read from the instrument when it is switched on and it makes
that the instrument operates in that way.

 CALIBRATION
The calibration described herein should be performed with the use of sample weights and/or product
pre-weighed on a weighing system.
Before proceeding with the calibration of the full scale, always perform the zero calibration.
During the calibration phase, the display shows the weight intermittently with the inscription CaL.
ATTENTION: At switching off the instrument without exiting the set-up menu, the programming executed
is not stored.
NOTE In the event that after calibration, the system shows linearity errors, you should verify that the
weighed structure is completely free of mechanical constraints.

 SERIAL COMMUNICATION PROTOCOLS

CONTINUOUS, AUTOMATIC AND MANUAL TRANSMISSION PROTOCOL

These protocols have been programmed into their programming menu.
The string is transmitted as follows:

STX <status> <net weight> <gross weight> <peak> ETX <chksum> EOT
Where
STX (start of text) = 0x02h
ETX (end of text) = 0x03h
EOT (end of transmission) = 0x04.
<status> = an ASCII character that can take the following values:
“S” = stable weight.
“M” = weight that is not stable (moving).
“O” = weight greater than the maximum capacity.
“E” = weight that cannot be detected.
<net weight> = field consisting of 6 ASCII characters of net weight.
<gross weight> = field consisting of 6 ASCII characters of gross weight.
<peak> = field consisting of 6 ASCII characters of peak.
<chksum> = 2 ASCII control characters calculated considering the characters between STX and ETX
excluded. The control value is obtained by executing the operation of XOR (or exclusive) of the 8-bit
ASCII codes of the characters considered. The result is a character that is expressed in hexadecimal
with 2 digits that can take values from “0” to “9” and “A” to “F”.
<chksum> is the ASCII encoding of the two hexadecimal digits.
In the case of continuous communication protocol, the given string is transmitted at a frequency of 10
Hz, regardless of the weight filter selected.
In the case of automatic and manual communication protocols, between 2 weight transmissions, the
weight must have a variation corresponding at least 20 divisions.

SLAVE TRANSMISSION PROTOCOL

LIST OF THE CONTROLS AVAILABLE:
• Request for the net and gross weight and current peak.
• Change in gross weight.
• Change in net weight.
• Command of reset or automatic calibration or peak reset.
• Programming the two setpoints of weight
• Requesting the programmed setpoints.
• Control of setpoints storage in permanent memory.
The unit connected to the instrument (typically a personal computer) acts as a MASTER and is the only
unit that can start a process of communication.
The process of communication must be made by the transmission of a string by the MASTER, followed
by a reply from the SLAVE concerned.

Page 39
CONTROLS FORMAT DESCRIPTION:
The double quotes enclose constant characters (observe upper and lower case); the <and> symbols
contain variable numeric fields.

STORING THE WEIGHT Setpoint IN A PERMANENT MANNER
Master: <Addr> “M” EOT
DAT 400: <Addr> “M” ACK EOT
In the case of communication error or otherwise unrecognized command from DAT 400, it will respond
with the following string:
DAT 400: <Addr> NAK EOT
FIELDS DECRIPTION
The double quotes enclose constant characters (observe upper and lower case); the <and> symbols
contain variable numeric fields.
<addr> = Serial communication address of the instrument; it is the ASCII character obtained by adding
80h to the number of address (i.e. address 1: <Addr> = 80h + 01h = 81h).
<csum> = checksum of the string data. It is calculated by performing the exclusive OR (XOR) of all cha-
racters from <Addr> to ETX excluded the latter; the result of the XOR is decomposed into 2 characters
by considering separately the upper 4 bits (first character) and lower 4 bits (second character); the
2 characters obtained are then ASCII encoded (example: XOR = 5Dh; <csum> = “5Dh” namely 35h
and 44h).
ETX (end of text) = 0x03h,
EOT (end of transmission) = 0x04h,
ACK (acknowledgment) = 0x06h,
NAK (No acknowledgment) = 0x15h.

Page 40
<status> = an ASCII character that can take the following values:
“S” = stable weight
“M” = weight that is not stable (moving)
“O” = weight greater than the maximum capacity
“E” = weight that cannot be detected.
<s1>...<s2> = 6 ASCII characters of setpoint.
<net weight> = 6 ASCII characters of net weight.
<gross weight> = 6 ASCII characters of gross weight.
<peak> = 6 ASCII characters of peak.
If the request is made cyclically, the weight is acquired with a maximum frequency of:

Frequency Baud Rate

50Hz 38400
35Hz 19200
25Hz 9600
8Hz 2400

Page 41
MODBUS RTU PROTOCOL
The addresses listed in the tables below follow the standard address specified in the guidelines of
the Modicon PI-MBUS-300. Below please find an excerpt that helps the user to communicate with the
instrument.
“All data addresses in Modbus messages are referenced to zero. The first occurrence of a data item
is addressed as item number zero. For example:
The coil known as ‘coil 1’ in a programmable controller is addressed as coil 0000 in the data
address field of a Modbus message.
Coil 127 decimal is addressed as coil 007E hex (126 decimal).
Holding register 40001 is addressed as register 0000 in the data address field of the message. The
function code field already specifies a ‘holding register’ operation. Therefore the ‘4XXXX’ reference
is implicit.”

To confirm a new value in E2prom, run the function of MAKE – BACKUP. If this function is not performed
by switching off, the DAT will return to the value before the change.
If not specified otherwise, the numerical values (such as addresses, codes and data) are expressed as
decimal values.
For any hardware configuration of the instrument (FIELDBUS or Analog), the MODBUS RTU protocol
is always available on COM1 RS232; in the event of Fieldbus absence, the MODBUS RTU protocol is
also available on COM2 RS485.

INSTRUMENT RESPONSE TIMES

In order to respond to most requests, the instrument takes a maximum time of 20 msec.
Exceptions are:
• the e2prom Backup command (max time = 350mSec.)
• writing of the registers of the cells capacity, cells sensitivity, net weight, system calibration, filter
(max time = 550mSec).

COMMUNICATION ERRORS HANDLING

The communication strings are controlled by the CRC (Cyclic Redundancy Check). In the case of a
communication error, the slave does not respond with a string. The master must consider a timeout for
the receipt of the response. In case of no answer, a communication error has occourred.

RECEIVED DATA ERROR HANDLING

In the case of string received correctly, but that cannot be executed, the slave responds with an EXCEP-
TION RESPONSE according to the following table.

EXAMPLE: CALIBRATION FUNCTION VIA MODBUS
To perform the calibration of full scale (that require the weight value in the sample set in the data register),
the value in the data register must be present when the command register is programmed. For example:
Calibrate the full scale using a sample weight of 2000 kg.
Write 2000 in the data register.
Write 0x0011 in the command register.
Use the multiple registers write function and write the registers of data register and command register
in a single command.

PRINT PROTOCOL
This protocol enables the communication with a printer. The data on the printed report are the following:
NET, GROSS and TARE (+ PEAK, if enabled).
PRG
The print command takes place by pressing the key or by activating the remote input #2. (*)
The printed report is issued only if the following conditions are met:
• Gross weight positive
• Net weight positive
• Stable weight (**)
• BLIND function disabled (***)
PRG
(*) In case the key is locked (see page 18) the print command can take place through the remote
input #2 only.
(**) The weight stability condition is controlled only if the “MOTION” parameter (see page 28) is set
to a value different than 0.
If MOTION = 0 the printed report is issued even if the weight is unstable.
(***) In case the BLIND function is enabled (see page 18) the print command can take place through
PRG
the remote input #2 only, not via the key.
Between one printout and the next one the weight must change for at least 20 counts.

THE USB CONNECTION BETWEEN THE DAT-400 AND THE PC
The hardware module installed inside the DAT-400 and allowing the instrument to be interfaced with a
PC through the USB port, is named CP210x, manufactured by Silicon Laboratories.
The CP210x module needs the drivers to be installed in the PC:
By installing on PCs the INNOVATION 2 utility software drivers will be loaded automatically. For in-
stallation refer to the manual.

Page 48
 ETHERNET INTERFACE CONFIGURATION
To configure the Ethernet interface it is necessary to use the PC application “ TCPBridge Configurator”
supplied with the instrument. To install the application, run the “setup.exe” file and follow the installation
wizard.
Connect the DAT 400 to the PC according to the two procedures:
1. Direct connection by using special ethernet cable called “cross“ or “crossover“.

2. Connection to a LAN Network (Local Area Network ) using ethernet “direct” cables . In this case,
the instrument must be connected to a network device (router , switch or hub ) to access the LAN.

From the Programs menu, select the application “

Configurator “ , under “ TCPBridge Configurator” .
You will see the screen as shown in the image here.
It may not be possible to immediately establish a
connection with DAT 400/Ethernet. This may be due
to an incompatibility between the programmed IP
address by default on DAT 400/Ethernet LAN and
the network in which the device is installed for the
first time. The IP addresses of devices on a LAN must
adhere to a certain format. Check in the PC “network
connection“ (Control Panel - > Network Connections)
the format of your IP address.
To configure the Ethernet interface of the instrument
DAT 400, follow the steps below.

Page 49
SEARCH DEVICES
To perform a search for devices DAT 400/Ethernet on the network,
press the “RICERCA BRIDGE”. Each device detected in the network
can be selected from the drop down “IP Bridge” menu; in additional
to that by selecting a specific device, it displays its MAC address
and the version of the firmware loaded on the device.
Select the device you want to configure.
To avoid communication problems, the application buttons are di-
sabled during the search of the devices.

PARAMETERS CONFIGURATION
After selecting the device you want to configure, perform the function
reading of the parameters currently programmed in the device. To
perform this function, use the “LEGGI” key, after a few seconds the
configurable parameters (see image at right) will be updated with
the values stored in the device at the time of the request.
These are the programmable parameters:
• IP Address: address of the device DAT 400, four numerical values
(values between 0 and 255, mandatory field).
• Subnet Mask: four numerical values (values between 0 and 255, this parameter can be omitted
or set to 0).
• Gateway: four numerical values (values between 0 and 255, this parameter can be omitted or set
to 0).
• Server Port: communication port for TCP / IP, numeric value between 1025 and 65535. This value
has different meanings depending on the selected protocol:
1. When the connection is established by other devices present in the network (eg a PC) to the DAT
400/Ethernet (TCP Server protocol or Modbus TCP Server protocol), the Server Port parameter
indicates the “TCP port” on which a Client device (eg, a PC) may perform a TCP connection
with DAT 400/Ethernet.
2. When the connection is established from DAT 400/Ethernet to a particular device in the network
(TCP Client), the Server Port parameter indicates the “TCP port” Device Server (for example, a
PC in the network) on which DAT 400/Ethernet can establish a TCP connection.
The TCP Client can only be used if PETH02 firmware is loaded in the Ethernet interface of the DAT
400/Ethernet instrument; check the firmware version after the search of the devices.
• Protocol: the device can be configured to operate in three different modes:
1. TCP Client: Select this protocol if you want that DAT 400/Ethernet (Client) establish as a con-
nection to a particular device on the network (Server). In this case it is need an additional input
parameter (Server IP), this parameter represents the IP address of the server to which DAT 400
must establish a TCP connection.
The TCP Client can only be used if PETH02 firmware is loaded in the Ethernet interface of the
DAT 400/Ethernet instrument; check the firmware version after the search of the devices.
2. TCP Server: Select this protocol if DAT 400/Ethernet (Server) must wait to receive TCP connec-
tions from other devices in the network (Client).
3. Modbus TCP Server: Select this protocol if DAT 400/Ethernet (Server) must wait to receive TCP
connections from other devices in the network (Client), which use the MODBUS TCP communi-
cation protocol.

Page 50
• BAUD RATE: THIS VALUE MUST ALWAYS BE SET TO 38400 BAUD.

• FRAME DATA: THIS VALUE MUST ALWAYS BE SET TO N-8-2.

The TCP Client can only be used if PETH02 firmware is loaded in the Ethernet interface of the DAT
400/Ethernet instrument; check the firmware version after the search of the devices.

TCP TEST CONNECTION

In case of “TCP Server” or “Modbus TCP Server” protocol, you can
test the connection directly via the “TCPBridge Configurator” PC
application (PWIN41). This function can not be performed in case of
“TCP Client” protocol. Manually enter the “Server Port” parameter, or
use the reading parameters function described on the previous page.
The “Server Port” parameter indicates the “TCP port” available by
DAT 400/Ethernet (Server) on which the “TCPBridge Configurator”
PC application (Client) can establish a TCP connection.
Press the “CONNECT” key to establish a TCP connection with DAT
400/Ethernet. The connection status is displayed in the “Stato Con-
nessione” section. To end a TCP connection press the “DISCONNETTI” button.
DAT 400/Ethernet can accept and maintain only one connection; before the test of the connection
make sure that other client devices in the network are not associated with DAT 400/Ethernet.
If the TCP connection test is successful (Stato Connessione: Connesso), the device DAT 400 is ready to
be used. The communication protocol selected by parameter “COM-2” (refer on page 34) is available
on the Ethernet interface of the device DAT 400.
The reset function of the ethernet interface of the instrument DAT 400 can be performed at any time (for
example in case of problems during testing of the TCP connection or when programming parameters),
using the appropriate “RESET” button. This function does not reset the instrument DAT 400, but only its
Ethernet interface.

 FIELDBUS PROTOCOL
FIELDBUS data exchange takes place on two separate memory areas, which are described in the
following tables.

WARNING:
The “Input Data Area” and the “Output Data Area” are of 128 bytes, except ETHERNET IP where the
value of the Input and output area can be set to values from 2 to 128 bytes, see page 36.
To transfer the parameters of the Output Data Area to the instrument you need to enable direct access
to the memory, writing the hexadecimal value 0x7FFF in the Command Register (1 word in writing) in
order to avoid that the instrument resets all its variables in the case of uninitialized Output Data Area
This command must be sent before the connection to inform the instrument that the parameters have
been initialized by the master. Now, the instrument continually tests the changes made to the parameters
and stores them only in case of real change.
