i am trying to read the status register from a wago 750-8202 with control fro pfc200 installed.
in the wago manual for e-runtime this is modbus registers 64010 - 64013. i need to be able to tell if the plc has stopped from the remote scada system.
thanks for any help.

Did you read the manual for 8202?

9.5.3 PLC Status Register
Register 0x1040 provides the status (state) that the controller is currently in.
Possible values:
1 = PLC running − PLC status is RUNNING.
2 = PLC stopped − PLC status is STOPPED.

9.6 Diagnostics
9.6.1 Diagnostics for the MODBUS Master
The status of the PLC, or of the control system, can be queried by the MODBUS
master by reading the WAGO-specific register 0x1040 – “PLC Status” using
MODBUS services FC3 (Read Holding Registers) or FC4 (Read Input Registers).
The WAGO-specific register 0x1040 – “PLC Status” is explained in the Section
“PLC Status Registers”.

hm... let me check, think this is possible but how is your SCADA connected by which fieldbus / modbus or is OPC UA an option too for your SCADA?
