Hi Luis,

Couldn't the firewall be blocking  the EPICS application ? 

Best Regards

Hi Mark,
My other application is using the Modbus protocol, I used it to do the
initial testing on my system.
I tried the telnet command from my MSYS2 environment and it can connect...

telnet 10.136.0.30 502
Trying 10.136.0.30...
Connected to 10.136.0.30.
Escape character is '^]'.

Kind Regards
                   Luis
