How to connect the data lines on the bus coupler if using the
bus coupler as an intermediate station:
1. Connect the incoming DDL line to X71 (1).
2. Connect the outgoing DDL line with the next module using
the X72 output (2).
How to connect the data lines on the bus coupler, if using the
bus coupler as an individual or last station:
1. Connect the incoming DDL line to X71 (1).
2. Close off the X72 connection (DDL OUT) (2) with the DDL
terminator plug (left figure, see "Spare parts and
accessories" on page 84). This ensures a defined line
termination and the valve system complies with the IP 65
