Optionally a programming unit or up to 10 operator panels are operated on the DP line simultaneously to the ET200 stations.
Using the programming unit
A variable table with the following scope is displayed online on the programming unit:
Using the operator panel
Up to 10 operator panels communicate with the DP master via the DP line.
All data of the DP master is located in 1 data block.
For the configuration of the operator panels, please refer to the following tables:
