Configuration - DNP3
28 Configuration Manual, 11/2018, C79000-G8976-C508-01
The receipt of sent frames is monitored and acknowledged differently depending on the
communication type and the telecontrol protocol.
The basic acknowledgment mechanisms are configured for the data link layer, see section
Transmission settings – DNP3 (Page 53).
A station module acknowledges a request from the master with its response frames.
The acknowledgment of unsolicited frames that a station module sends to the master is
configured in the "Settings DNP3 station" parameter group, see section Settings DNP3
station (Page 56).
Acknowledgment in Open User Communication
The successful sending and receipt of frames is indicated by status displays of the program
blocks.
With TCP segments, the protocol-specific acknowledgement mechanisms are used.
