'''Modbus''' is a serial communications protocol. Simple and robust, it has since become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices. This chapter is an overview of the '''Modbus''' function in RUT routers.

'''Modbus TCP''' interface allows the user to set or get router parameters like modem temperature, signal strength, etc. In other words, '''Modbus TCP''' allows you to control the router's behavior and get its status information. Modbus daemon acts as slave device. That means it accepts connections from the master (client) and sends out a response or sets some system related parameter. By the default Modbus will only accept connections through LAN interface. In order to accept connections through WAN interface also, Allow Remote Access must be checked.
