How do we use an RTU?
EMR use RTUs throughout many of our client networks to monitor field-based assets based on digital or analogue technologies. This data is then transmitted back to a central monitoring station or SCADA.
Our RTUs interface to multiple master stations and IEDs (Intelligent Electronic Device) with different communication media (usually serial (RS232, RS485, RS422) or Ethernet).
An RTU may support standard protocols (Modbus, IEC 60870-5-101/103/104, DNP3, WITS, IEC 60870-6-ICCP, IEC 61850 etc.) to interface any third-party software.
