I am using V130 PLC with Ethernet card configured as Modbus IP slave to communicate with desktop PC running control software configured as Modbus IP Master. I am able to communicate, data exchange happening perfectly. Now I want to know IP address of desktop PC (Modbus master) to which PLC is currently connected, this is to limit connection with only desktop PC at a time. Are there any system operands which holds IP address of Modbus master when PLC configured as Modbus slave?
