6.4 Activating the bus terminating resistor

Bus terminating resistor

The PROFIBUS must be terminated by a bus terminating resistor at the physically first and

last station.

The bus terminating resistor is in the bus connector (¶ 128)and is activated using a

switch.

) Note!

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

terminators at the cable ends remain active.

ƒ Please note that the bus termination is no longer active if ...

– the connector has been disconnected e.g. in service case;

– the voltage supply of the communication module has been switched off.

6.5 Setting the software compatibility

) Note!
