Wiring

Warning!

If the 2131 fieldbus module is no longer supplied with voltage, the bus system will continue

operation. However, the connected controller can no longer be accessed from the host.

If single bus participants are to be disconnected, it must be ensured that the bus terminators

at the physical cable ends remain active.

Only use cables which correspond to the listed specifications (see chapter 8.1).

Observe the bus connector drawing. ( 4-6)

Connect the controller using the bus connector.

Note: The bus system will not be interrupted if the bus connector is pulled off the controller.

Connect a bus terminator to the physical bus ends. The bus terminator is integrated into the

bus connector and can be activated via a switch.

Observe the wiring notes and the documentation for the control system.
