Configure Modbus Redundancy Alerts

Post by emaddocks »

Hi,

Does anyone know how to configure alerts for when one of the redundant hosts configured in the Modbus PLC configuration loses connection?

Does the Modbus driver provide this functionality? I haven't been able to find anything that looks like it would in the internal _Mod_Plc DPT.

Cheers
Eric

The connection state for a PLC connection is written to the "ConnState" element for the _Mod_Plc datapoint.
Detailed information can be found in the WinCC OA Documentation:
