<b>Modbus</b> is a serial communications protocol. Simple and robust, it has 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 TCP functionality for {{{name}}} devices. | <b>Modbus</b> is a serial communications protocol.

Modbus parameters are held within <b>registers</b>. Each register contains 2 bytes of information. For simplification, the number of registers for storing numbers is 2 (4 bytes), while the number of registers for storing text information is 16 (32 bytes). The register numbers and corresponding system values are described in the table below: | Modbus parameters are held within <b>registers</b>. Each register contains 2 bytes of information.
