Sensor dan aktuator
RTU VS PLC (1) A Remote Terminal Unit (RTU)
– an industrial data-collection device – designed for operation at a remote site, which communicates data to a host system by using telemetry such as radio, dial-up telephone, or leased lines.
RTU VS PLC (2)
RTU : A standalone data acquisition and control unit, generally microprocessor based RTU primary task : – To control and acquire data from process equipment at the remote location – To transfer this data back to a central station.
RTU VS PLC (3)
PLC : – special-purpose computer used in industrial monitoring and control applications – have proprietary programming and networking protocols, and specialpurpose digital and analog I/O ports.
PLC (keuntungan dibanding RTU) Economic solution Versatility and flexibility Ease of design and installation More reliable Sophisticated control Physically compact Easier troubleshooting and diagnostics
