Modbus TCP Register Table

The latest firmware provides the initial release of the Modbus TCP/IP client service support for factory
automation applications. You can implement the modbus command using the command line interface in
console and Telnet modes, which allows you to modify some parameters such as, idle time, number of Modbus
masters, and the Modbus service port.
Note: The Modbus TCP client returns 0xFFFF to a Modbus master when pulling a reserved address.
