3.1 Installation

3.1.1 Handing
WARNING
The electrostatic discharges may damage semi-conducive devices within the module, if the
connector pins are in contact with the backplane.

Please note the following precautions to avoid electrostatic damages:

• You should handle the module from the front side, as far as possible from the backplane
connectors.

• You should never touch the pins of the backplane connector.

• You should keep the module in its antistatic bag or packaging box, when unused.

3.1.2 Module Location within the Chassis or Backplane

All modules must be installed always in vertical position.

All SM_SER modules in the RTU must be installed in the first backplane. Communication data can
be expanded to others backplanes. Then, the maximum number of SM_SER modules connected to
a CPU is 8.

When using a power supply such as the SM_PS or SM_PS40 module, it must be located in the
position 1 (slot1 left-hand side). In redundant-power supply configurations, there must be two
reserved positions for the two power supply modules. These positions must be 1 and 2.

Remaining modules can be located in any position (slot) within the chassis.

Figure 7 – Backplane positions

Modules must be grouped to minimize the adverse effects caused by noise and heat, therefore,
modules, and more specifically the CPU modules, must be placed as far as possible from the
modules which operate at alternating currents or high currents.
If the system has redundant CPUs, both control modules must be put together in the backplane

3.1.3 Power Supply Requirements

WARNING
The voltage input for the backplane is 5.4 ± 0.2 VDC. The external voltage input isn't protected
against overvoltage nor polarity inversion, so an incorrect wiring or an incorrect adjustment of
the supply voltage could damage electronic.

Pag 21
13/12/2019 User Manual – SM_SER

The SM_PS and SM_PS40 modules (power-supplies) are scalable to supply power to the modules
connected to the backplane, as required. When using auxiliary power supplies, it is necessary to
scale them depending on the installed Saitel DP modules.
The consumption of all modules will be added plus a safety margin (between 20% and 50% of the
full power). The power supply efficiency typically, 70 - 90% shall also be considered, to protect the
chassis and power supply from overloading.
The maximum power requirement for each SM_SER module is: 3.9 W.

3.1.4 Mounting Procedure

Saitel DP modules can be installed in a 19-inch chassis (SM_CHX) or a backplane SM_BPX.
When SM_BPX module is used, some problems with the installation of the modules are detected.
On the other hand, there are some configurations working correctly but the modules haven´t been
mounted correctly. This situation produces a mechanical instability and might cause serious
problems.
Following picture shows three modules inserted on the backplane. One of them has been inserted
incorrectly in spite of it is functional totally.
Figure 8 – Saitel DP module inserted incorrectly

Consult application note FTE-AN010-F700 for more information about:

• How the user should mount a Saitel DP module on a panel-mounted backplane.

• How the user should verify the installation.

• Actions that the user should do when an incorrect mounting is detected.

To mount the module in the chassis or backplane, please follow the following instructions:

• Switch off the power supply.

• Mount the module at the desired position, and if you are using a backplane mounting,
verify that the rear rails are properly mounted using the pre-drilled holes on the
backplane.

• Firmly press the module to assure the connector fits in the connector properly. Check
whether the module is correctly mounted to the backplane base.

• Fix the module using the screw located at the top.

3.1.5 Configuration Switches

The module’s identification and Profibus communication speed can be set using the microswitches
on the module's rear panel. Switches 1 to 4 are used to configure the multiplexer's address. The
position allocation is shown in the following table:

Pag 22

3.2 Wiring SM_SER

The module integrates 8 channels supporting RS-232, RS-485 or RS-422 communications:

The pin numbers in the RJ-45 connector are the same in all cases. SM_SER module does not
include LED indicators in the connector base. All connectors are RJ-45 type.

3.2.1 Recommendation for EMC

In order to avoid EMC disturbances, the following considerations must be follow.
The communication bus can be installed using 2-wire communication or 4-wire communication. In
order to increase the immunity to electromagnetic interference (EMC), the use of a shielded twisted
pair is recommended.

WARNING
Particular care must be taken when connecting the shielding to make sure it is effective.

The shield connection depends on the equipotentiality between the connected devices:

• Guaranteed equipotentiality: Both devices are connected to a ground system, so that the
same potential level is guaranteed. The shield must be connected at both ends.

• Limited equipotentiality: Both devices are connected to ground but not to the same ground
system. To limit the difference of potential that can be produced among them a cable with the
appropriate cross-section will be installed between the grounding of both. The shield must be
connected at one end.

• No guaranteed equipotentiality: Ground connection of both devices can’t be guaranteed

(both devices must be connected to a ground system). Copper mustn’t be used in this case.

DANGER
Connecting NOT equipotential devices could be hazardous for persons and equipment.

3.2.2 Wiring RS-485

For RS-485 the pairs are shielded individually or all together by a copper braid. The
recommendations for the cable are:

• Resistance: < 100 Ω/km.

• Section: 0.22 mm2 (24 AWG)

• Characteristic impedance: 120 Ω.

• Maximum length: 1200 m.

The cabling for a half-duplex communication is:

• Join wires 1 and 8 (Rx(-) / Tx(-), B/Z or Negative (-)).

• Join wires 3 and 6 (Tx(+) / Rx(+), A/Y or Positive (+)).

• Join wires 4 and 5 to GND.

3.2.3 Wiring RS-422

For RS-422 the pairs must be shielded individually. The recommendations for the cable are:

• Resistance: < 100 Ω/km.

• Section: 0.22 mm2 (24 AWG)

• Characteristic impedance: 100 Ω.

• Maximum length: 1200 m.

3.2.5 Termination Resistor (RS-485 and RS-422)

In a communication bus (RS-485 or RS-422) the devices installed on the ends of the bus must
include a termination resistor. Usually, this is the case of the SM_SER module where its
communications ports exclude the possibility of installing this resistance.

Pag 25
13/12/2019 User Manual – SM_SER

For each communications port that works as end of the bus, a terminal with termination resistors
(120 to 150 Ω) for both reception and transmission channels must be installed.
NOTICE
It is important to note that for each bus, two and only two devices must function as
termination of the bus.

There are two recommended models for these auxiliary terminal (both by Phoenix Contact):
Figure 9 – FL-PP-RJ45-SC and VIP-3/PT/RJ45

For example, the following figure shows how you can use a 5-pin terminal for RS-422 and for RS-
485 in full-duplex communications:
Figure 10 – Termination resistor in full-duplex communications

For RS-485, using half-duplex communications, a 3-pin terminal must be used:

Figure 11 – Termination resistor in half-duplex communications

NOTICE
These figures should be understood as an example. You can use some other
mechanism that provides you with the same functionality.

To connect the SM_SER port with the auxiliary terminal, if the bus is RS-422 or full-duplex RS-485,
the cable to be used is shown in the following figure:
Figure 12 – Cable for connection SM_SER-Auxiliary terminal in full-duplex communications

3.3 LED Indicators

The following led indicators are available in a SM_SER module:

Figure 14 – LED indicators

• General Diagnostics (DIA)

• Operation status (RUN)

• One diagnostic LED for each block of 4 communication channels (ST1/ST2)

• Thirty-two indications for the channel signals. Four indications for each channel to display the
“Transmission” status (TX1-TX8), “Reception” (RX1-RX8), “Request to Send “(RTS1-RTS8)
and “Clear to Send” (CTS1-CTS8).

Figure 16 – Add, remove or change I/O modules

Each I/O module is allocated to a unique and identifying number in the bus (Profibus address). This
number is assigned using the switches available in the rear panel of the module.
The CPU needs to know the address and the types of I/O modules installed in the bus in order to
initialize and switch to data acquisition mode properly.
All examples in this chapter are made using an SM_CPU866e CPU but all operation is similar for
SM_CPU866.

ready and activation of the RTS
 DTR – RTS delay: Timeout before establish the RTS signal when DTR has
been activated
 Timeout CTS: Standby time from the activation of the RTS to the activation
of the CTS. If the CTS value is zero, it means that the transmission will be
done regardless of CTS value. For non-zero values, channel transmission
is controlled by the CTS; if the time defined in this attribute elapses without
a CTS activation, then the package pending to be sent is discarded
 RTS(or CTS) message delay: Elapsed time from the activation of the CTS
to data transmission
 Message – RTS delay: time from the end of the data transmission to RTS
deactivation.
NOTICE

For 2-wire RS-485 communications, it is very often necessary to set the RTS control to TOGGLE,
and define all times to 0 ms. Thus, reception while transmitting is disabled (to avoid echo).

4.4 Firmware Upgrade

Once the backplane is configured, the CPU module (866 or 866e) already knows the type of
acquisition blocks that are been installed and their corresponding addresses.
To update the software of the SM_SER module, you need:

• A console connection with the CPU.

• SM_SER module must be correctly addressed and working fine in the backplane (LED Run
must be blinking).

• SM_SER.bin file with the new version. This file must be available in the flash folder of the CPU.
If not, you can contact Schneider Electric in order to ask for it. Use an SFTP client and transfer
this binary file into the CPU flash folder.
The console tool can be executed using any commercial tool for serial or SSH connection. In this
manual, PuTTy software is used.
Open a serial connection as follow:
Figure 32 – PuTTY configuration

SSH connection via Ethernet can be used too. More information about the console use in the CPU
user manual. In the following picture, CPU866e is used:
