MODBUS TCP/IP between two PLC's AC500 V3, ETHx_MOD_MAST function block with code of error unknown (256)
I'm working on a project with AC500 V3 PLC with PM5630 CPU using Automation Builder V2.2.3 . I'm using MODBUS TCP/IP communication between two PLC's of the same. I'm working with the ETHx_MOD_MAST function block and i have an output code of error 256 (Decimal) which is not in the error messages of the function block libraries of MODBUS communication. I was wondering if someone could help me solve this issue.
