Modbus-TCP
« on: March 10, 2021, 06:43:31 AM »
Hi,

I'm stuck into project where I'm reading data from Siemens PLC and moving it to Modbus-TCP on virtual port 127.0.0.1.

When I run it in my PC everything runs fine but when I put it in DCS system it stops moving data to Modbus-TCP slave.

Can some one guide as to what might be the problem with existing system and what could be done to rectify it.

P.S: DCS SCADA is Emerson Make.

Without knowing your setup, I would guess that your DCS doesn't know what virtual port 127.0.0.1 is.
