Process Communication Unit, PCU400
PCU400 is used for flexible and effective data acquisition in SCADA systems.
The PCU400 handles communication with RTUs, IEDs and Substation Automation System. It provides flexibility, performance and scalability in a cost-effective manner. PCU400 supports a number of different protocols. Each unit connects up to 64 asynchronous communication lines at rates up to 64 kbit/s.
PCU400 features:
- Different protocols configured per communication channel
- Bit-oriented protocols with OCC2-8 hardware
- Cyclic scanning of RTUs and scan groups
- Reduces SCADA server I/O overhead
- Connected to servers via LAN/WAN (TCP/IP), dual LAN
- Performs dead-band-based report-by-exception of data to the SCADA server
- Data engineering with SCADA engineering tool or Excel-based tool
