PLC vs RTU vs IED
Difference Between PLC, RTU, & IED PLCs and RTUs are both electronic devices; their functionalities overlap with each other. RTCs are sold with PLC-like features, and PLCs are sold with RTC-like features. Many vendors sell proprietary alternatives and different associated environments to run these programs since the industry made the functional language running RTUs and PLCs standard. RTU “ RTU” stands for “Remote Terminal Units.” They are also referred to as “Remote Telemetry Units.” An RTU is an electronic device which is controlled by a microprocessor. The main function of an RTU is to interface the SCADA to the objects present physically. “SCADA” stands for “supervisory control and data acquisition.” The interface between objects and SCADA takes place by using supervisory system messages to control all the objects connected and by transmitting to the system all the t
