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ƒ Please note that the bus termination is no longer active if ...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!
If the EMF2131IB communication module is replaced by the EMF2133IB
communication module, ...
ƒ do not change any host settings;
ƒ set the DIP switch S8 to the "ON" position.
