I am trying to read modbus data from a modbus slave simulator in codesys2.3 using Ethernet_Modbusmaster_TCP/UDP FB.
It is giving me error code 1 which is incorrect function code, I am using FC3 for this purpose.
But when I do modbus read from a Wago controller, it is working fine.
Please can anyone help me on this.
also find the attached code for reference.
