    Ausrufezeichen VERY URGENT. Zenon for dispatch SCADA station for the oil and gas

    We have 3 SCADA system running with Zenon.

    The 3 SCADA system are interconnected through fiber optical network. (Hundred kilometers between each SCADA station)

    Each SCADA system is a master station connected to a slave IEC60870 or IEC61850 PLC unit.
    (This is for an Oild and Gas project, so we cannot used the protocol we wants, but have the choice with DNP3,IEC and Modbus);

    The specs required that for the three SCADA, if one of the three SCADA failed, one of the two other SCADA take the control and save all archives data.

    Is it feasible with Zenon, if yes can you send us the architecture of the solution and which driver communication youwould recommend (DNP3, IEC, Modbus)

    Thank you for your quickest help!

    Such a constellation would exactly fit to the "Circular Redundancy" concept.

    Take a look at following help documentation:
    Tutorials -> zenon network -> The multi-server network -> Special requirements for the integration project -> Circular Redundancy

    Due to the distance between each Server is very long you may have to consider the watchdog timers.
    Check the according settings in following chapter in the help documentation:
    Manual -> File Structure -> Structure and syntax - ZENON6.INI
    -> Chapter [NETZ]

    Regards,

    One thing which I want to add:
    Please also consider when implementing a "Circular Redundancy" network that the timesynchronization should be done externally (not via the zenOn timesynchronization mechanism which is activated per default).

    see also in the help documentation at:
    Manual -> Network -> Configuration of the network -> Settings under Windows -> Time synchronization in the network

    Regards,
    Herbert
