Take advantage of our serial communications protocol module. Designed to work with Programmable Logic Controllers (PLCs) and commonly available as a means of connecting industrial electronic devices, the Modbus module is used to interface with various controls systems, SCADA and BMS to generate event and alarm messages. Example – The Modbus module acts as the communicator between a system that measures temperature and humidity and the computer that oversees its operation. It is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.
