MODBUS TCP/IP error 12325
I am trying to connect AC500 PLC PM573-ETH with panel CP430T-ETH through Modbus TCP/IP but I cannot. I am using ETH_MOD_MAST block to communicate but the result is always error 12325 - Address error according to help. Can somebody explain me what can be the problem? What address is the problem? In ETH_MOD_MAST block I am using these parameters:
Slot - 0 (internal slot)
IP - 192.168.0.20 (address of the panel)
Unit ID - nothing
FCT - 01 (read n bits)
ADDR - 0
NB - 05 (1bit to read)
DATA - ADR(bPanel) - bPanel is BOOL variable
Thanks in advance for your help
