You can now build and download your project to the PLC, if no errors occurs , your DP system should start and you should be able to monitor directly the data exchanged between the PLC and its slave.

The following screen displays the ON line status of the PBY 100 Master module. The slave 2 (ATV312 here) is currently monitored:

In this view we can see %IW0.3.0.4 which corresponds to ETA , and the value of the current speed (in rpm) in %IW0.3.0.5 which represents RFRD.
