ADS Interface
Communication can also take place via ADS in TwinCAT systems. The functionality is extremely similar to
that of an ADS connection between two PCs over Ethernet, although transmission takes place over
PROFIBUS, with the exception that the requester that initiates the ADS job is always the DP master PC. An
EL6731 DP master is then linked to an EL6731-DP slave.
In the DP master, the ADS Interface should be activated on the "ADS" tab of the box, and the Net-ID of the
DP slave PC is to be entered:
