In order to minimise wire reflection and ensure a defined idle level in the PROFIBUS-DP transmission line, the transmission line must be equipped with a bus terminator at both ends. The bus terminator is integrated in the equipment for bus module RMVDP/F. Switches S8-S9 are located below the PG screw cap.If the bus module is attached at the end of the transmission line, the bus terminator must be activated.
The address provided/used for the bus module is inscribed on the bus module in the bus participant's (slave) field. 3.2 Bus module mounting The bus module is placed on the multiple plug connector of the valve block system and screwed tight.
Field bus connection –
The BUS INX71 plug for connecting the incoming field bus cable and – the BUS OUTX72 socket for connecting the outgoing field bus cable are located on the RMVDP/F bus module. If it is the last station in the field bus connection, the remote bus is only connected to BUS IN X71 and closed via switches S8-S9 using the bus terminator supplied internally. A PG protective cap is put on the BUS OUTX72 socket.
