Sensor dan aktuator (Field Devices) RTU (Remote Terminal Unit ) atau PLC Sistem Komunikasi




Master Terminal Unit





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

Sistem Komunikasi







RS 232 Private Network (LAN/RS-485) Switched Telephone Network Leased lines Internet Wireless Communication systems – Wireless LAN – GSM Network – Radio modems
