5.2.4 Connection of Optocoupler outputs (Connection X2)
Note
The optocoupler inputs are placed at the supply voltage connection X1
The corresponding cable plugs are part of the standard scope of supply.

Optocoupler outputs for fast switching operation
For reasons of velocity and for diagnostic purposes it could be useful to issue the relevant
switching signal 0-sheet, 1-sheet, 2-sheet via a real-time interface. By doing this latency periods
and cycle times of fieldbus communications are eliminated.
5.2.5 Fieldbus connection (Connection X3 and X4)
5.2.5.1 Profibus-DP
According to the Profibus-DP Organization (PNO) for the protection class IP67 a round connector
M12 with inverse coding should be used. A “T-Connector“ (TEE) is not necessary, because the
control unit is equipped with input and output connectors.
The corresponding cable plugs are part of the standard scope of supply.
Note
If the L20 is the last participant in the bus, then an external terminating
resistor should be placed into the open connector.
The resistor is
not
within the scope of supply.
