We are currently working with the Advantech ECU 1051 to establish communication to SCADA via IEC 104.
Our setup involves sending data from the PLC to the Advantech using Modbus TCP, which is then forwarded to SCADA via IEC 104.
We need a tag or parameter to indicate when communication is lost between the SCADA and Advantech, so the PLC can read this information via Modbus communication and trigger a switch restart.
Is there any tag or parameter that represents the quality of IEC 104 communication?
