This function allows the administrator to specify Modbus TCP/IP client devices that have or do not have access to serial slave devices connected to the ETG.

NOTE: There is an anonymous Modbus TCP/IP address (***.***.***.***) that can be set to Read-only or None. Setting it to Read-onlyallows any Modbus TCP/IP client not in the filtered list to access serial slave devices with read-only access. Setting it to None blocks all Modbus TCP/IP clients not in the filtered list.
