ModbusTCP - What type of protocol is Modbus TCP

Modbus TCP

Modbus TCP is part of the Modicon Modbus family of protocols and operates over standard Ethernet using the TCP/IP transport layer. Because it is an open and widely adopted protocol, Modbus TCP is commonly used in building automation systems, intelligent buildings, and industrial automation networks.

Using a FieldServer or QuickServer gateway, Modbus TCP values can be read from field devices and made available to other systems, or served to Modbus devices from non-Modbus sources. Depending on the application, the gateway can operate as a Modbus TCP client (master) or as a Modbus TCP server (slave).

In protocol conversion scenarios, the FieldServer acts as an intermediary that translates Modbus TCP messages into a wide range of other building automation protocols. This allows Modbus TCP devices to integrate cleanly into multi-protocol environments without modifying the original equipment.
