The RTU, also called a remote telemetry unit, is a special purpose data acquisition and control unit designed to support SCADA remote stations. RTUs are field devices often equipped with wireless radio interfaces to support remote situations where wire-based communications are unavailable. Sometimes PLCs are implemented as field devices to serve as RTUs; in this case, the PLC is often referred to as an RTU. [1]
Special purpose data acquisition and control unit designed to support DCS and SCADA remote stations. (from:NIST SP 800-82 rev 2) [1]
RTUs are field devices often equipped with network capabilities, which can include wired and wireless radio interfaces to communicate to the supervisory controller. Sometimes PLCs are implemented as field devices to serve as RTUs; in this case, the PLC is often referred to as an RTU.
