Assigning Parameters to the CP 541 for the Connections
In the connected programmable controller, you must observe the following
points when assigning parameters:
The station number set in the CP 541 must be identical to the node ad-
dress of the connected programmable controller.
Establish the DP connection in the connected programmable controller for
node address 0.
The DP connection always has a constant length. The number of data
words for sending must agree with parameter NWO in the CP 541.
Up to 16 data words per direction can be transferred via the DP connec-
tion.
You must observe the following points in the DP master:
The CP 541 cannot be assigned parameters by the DP master with refer-
