MODBUS TCP/IP COMMUNICATION
Greetings of the day,
I am using Kepware as OPC to communicate with my SCADA. I have configured "one" as real in the Codesys As you can see in the picture. Is it possible to take it to the Kepware OPC? If I have configured it as Global variable with a 32 bit addressing from Kepware?

Greetings,
If you want to use Modbus TCP Protocol, you need to define it with Holding Register Address, it must be like Var1 AT %MD0:Real; otherwise you can not read with Kepware.
If you want to use OPC, you dont need to define any Holding Register Address etc.
Hope it helps.
