6 Electrical installation

Wiring of the PROFIBUS

ƒ Wire the PROFIBUS nodes to each other.

Only use cables which correspond to the listed specifications (40).

ƒ Activate the bus terminating resistor in the bus connector at the first and last

physical node.

– PROFIBUS cables with an integrated bus terminating resistor can be freely

purchased from various cable manufacturers.

– The bus terminator is supplied by the node. The external supply of the

communication module feeds the bus terminator independently of the standard

device supply (43).

 Note!

ƒ If you want to disconnect individual bus stations, ensure that the bus

terminators at the first and last physical bus station remain active.

ƒ The bus terminator is no longer active if ...

– the connector has been pulled out e.g. in the event of service;

– the voltage supply of the communication module has been switched

off.
