I'm triying to read coils and holding registers from a ABB AC500eco PM556 ETH PLC. I get conexión with the demo application and with my own application, but when I send the reading instruction I get an error message.
When I send 00 01 00 00 00 06 01 03 FF FF 00 02 I get no modbus response from the PLC an I get the next error: "the transport connection data can not be read: a connection established by the software on your host computer has been overridden"
I also attach wireshak screenshots where you can see the error response from the PLC

Hello,
I already use Delta and Schneider at the same time within my own applicatioin and sometimes I use EasyModBus for some debugging. I do not face any problem.
