I have downloaded Modbus Poll software ,so I can siulate SERVER and client.
In my example Server is PC with IP - 192.168.0.17
SLAVe is PLC 192.168.0.99
I manage to connect to MASTER NETWORK with Modbus Poll software
with following settings
Connection : MODBUS TCP/IP
Remote Modbus server, IP : 192.168.0.99 port 1201
Setup settings inside Modbus Poll software ( read/writte)
Slave_ID :1
Function: Read holding registers
Adress : 0
Quantity : 1
Scan rate: 1000ms
But read/writte is not working
Inside PLC I am using ETH_MOD_MAST function.

My Variables are inside PLC:
DATA_WRITE AT %MW0.0 : WORD; (this value i am trying to transfer)
rest of variables are inputs and outputs of the "ETH_MOD_MAST" function
Any help, I can give all settings inside PLC. But its nutin beside this function and the IP adress
