IP address of Modbus TCP slave needs visiting: Input IP address of Modbus TCP slave which gateway wants
to visit.
Device status: Open, close optional. When opened, “memory mapping address” and “memory mapping bit
offset” is optional. Users can see the communication state between this node and gateway in EtherNet/IP input
data.
Memory mapping address: Address range that equipment state is mapped in the module memory,
0x0000~0x01EB. Calculate by clicking “Auto mapping”.
