Mounting and Disassembling the Communication Modules

Communication Modules are mounted on the left side of the Processor Module on the same Terminal Base. The electrical connection is established automatically when mounting the Communication Module.

Attention

:strong:Risk of damaging the PLC modules!

The PLC modules can be damaged by overvoltages and short circuits.

  • Make sure that all voltage sources (supply and process voltage) are switched off before you are beginning with operations at the system.
  • Never connect any voltages or signals to reserved terminals (marked with —). Reserved terminals may carry internal voltages.

After mounting the Terminal Base, mount the Communication Modules.

  1. First insert the bottom nose of the Communication Module into the dedicated holes of the Terminal Base. Then, rotate the Communication Module on the dedicated Terminal Base slot until it is locked in place.

    Warning

    :strong:Risk of malfunctions and damages to persons!

    Unused slots for Communication Modules are not protected against accidentally touch. Dust and Dirt may cause contact problems and malfunctions.

    Unused slots for Communication Modules must be covered with Dummy Communication Modules (TA524 TA524 - Dummy Communication Module).

    I/O-Bus connectors must not be touched during operation.

  2. The disassembly is carried out in a reversed order.

    Press above and below, then rotate the Communication Module and remove it.
