  • PCS-9794 Protocol Converter

  • PCS-9794 is a protocol converter designed for the highest standards of performance, safety and reliability to meet requirements of a complex substation automation system (SAS). As an integral part of the SAS, it works as a communication manager, which maps signals between IEDs and the local SCADA or protection management unit. 

    PCS-9794 transmits data to local SCADA or protection management unit through the IEC 61850 or IEC 60870-5-103, etc. protocols, and links IEDs with protocols such as Modbus through different kinds of communication interfaces.

  • Protocol conversion
    PCS-9794 can adapt to the signal conversion need of different projects and realize the data exchange between station level and bay level network communications.
  • Information acquisition of relay, meter and other IED
    Through its serial ports and Ethernet ports, this device can communicate with relay, meter and other IED to gather their information such as SOE and operation signal.
  • Communication
    • This device can communicate with local SCADA and protection management system.
    • This device can communicate with RTU to realize the data transmission to dispatching center or distributed control center.
    • The mapping transmission tables for SCADA or RTU can be customized independently.
  • Communication status supervision
    The mapping transmission tables for SCADA or RTU can be customized independently.
  • Signal synthesis
    The signal synthesis function is supported with the help of the configuration tool PCS-COMM. Logical and mathematic operation of data such as AND, OR, NOT, XOR, +, -, × and ÷ can be proceed for the transmission to remote control center.
  • Local binary output
    Several output contacts are equipped with the optional IO module to realize logic output. These outputs are configurable through the auxiliary software.
  • Configurable LED indication
    Several LEDs are equipped on the device HMI panel to indicate a binary signal, such as alarm, communication state, switchgear position, etc. Some of them are defined by default while the others are configurable in 3 colors (green, red and yellow) through the auxiliary software.
  • Manipulation authority
    All device critical manipulations, such as remote control and setting modification, need a user authority check. The authority password is configurable via local LCD.
  • Command record and query
    This device records all the commands and operations, which include control selection, control execution, regulation, setting modification selection, setting modification execution, signal reset, etc. All these records can be viewed and queried with filter.
  • History event record
    This device automatically records the events during its service, which include self running state change, alarm from connected IED, communication failure alarm, etc.
  • Double device redundancy strategy
    Several device redundancy strategies are supported. The 2 devices are completely electrically independent. Their power supplies, communication ports and programs run independently. The inter-device exchange is realized electrical and network connection.
  • Consistency IP for dual network
    For the downlink dual network mode with 2 devices, master and slave communicate with substation IEDs in using the same substation network IP address.
  • Time synchronization (79)
    This device supports several time synchronization mode, that include PPS, PPM, IRIG-B, timing message and SNTP. Thus, internal clocks of connected IEDs will be unified in the substation.
  • On-line maintenance and monitoring
    This powerful function enables the engineer to monitor the running status of this device through network, including running information print, message display of Ethernet port and serial port, on-field configuration, database view, virtual measurement, file transmission, remote rebooting, etc. With all these advanced functions, the substation upgrade becomes convenient.
  • Self-diagnosis
    During device service, it keeps a full supervision on software and hardware. Once an abnormality occurs, the device will be self-blocked to ensure no further mal-operation and send an alarm. For the dual device mode, if the abnormal device is on-duty, it will not only block itself but also activate the backup device to take over all its task to ensure the stability and reliability.
