Retrofitting interfaces

This section describes how to retrofit the modules for optional interfaces of central processing unit
705002.
CAUTION!
Incorrect handling may result in damage or malfunctions.
This compromises the function of the central processing unit or the system as a whole.
 Only qualified personnel are permitted to carry out module retrofits. The country-specific require-
ments regarding changes to an electrical device must be observed. Before a retrofit, the system must
be shut down and isolated from the power supply.
CAUTION!
Modules may be damaged by electrostatic discharge.
This compromises the function of the central processing unit or the system as a whole.
 Modules may only be retrofitted at a grounded workstation and in compliance with the relevant safety
measures.
Identifying the module
The module can be identified using the part no. on the packaging.
Assembly
RS232 Modbus-RTU (as of system version 3)
RS485 Modbus-RTU (as of system version 3)
Ethernet (RJ45)
NOTE!
For modules that have already been fitted at the factory, the type designation on the nameplate of the
central processing unit indicates the module type and interface.
If required, information regarding this can be found in the "Identifying the device version" chapter in op-
erating manual 70500200T90 or installation instructions 70500200T94 (the installation instructions are
included in the scope of delivery of the device).
Shutting down the system and removing the central processing unit from the DIN rail
1. Shut down the system and disconnect it from the voltage supply. To do this, loosen the 2 screws of
the wired terminal strip +24V/GND and pull the terminal strip forward.
2. If necessary, remove other connecting cables (USB, LAN).
3. Disconnect the central processing unit from the modules and remove from the DIN rail. To do this,
please follow the instructions on dismounting previously provided in this document.
