    Default OPC UA Server Redundant ausführen

    Hallo!

    Wie kann ich mit dem OPC UA Client Treiber eine redundante Verbindung zu zwei (jeweils auf den Zenon Servern laufenden) Process Gateways - OPC UA Server - einrichten?
    Anders gefragt, wie kann ich mit dem OPC UA Client Treiber eine redundante Verbindung einrichten?

    Danke!

    Mit freundlichen Grüßen
    Peter

    Ich werde auf Englisch antworten damit eventuell auch die Anderen was davon haben:

    To have redundant connections to 2, or more, (identical or similar) devices you can create 2 driver instances; or in one driver instance - create 2 connections. Then create 2 sets of process variables. Then create one additional set of ADP (Alternative Datapoint) driver variables, merging each 2 process variables (one from device A, second from device B) to a single ADP variable.

    By ADP variables configure the additional (can be common for all, internal) variable to decide which device is currently the "winning" one. The user, in ADP variables, will have information from this chosen device, while both driver instances will keep running connections to devices simultaneously.

    BTW, this could be solution for any driver, not only OPC UA.

    OPC UA (Open Platform Communications Unified Architecture) ist eine Sammlung von Standards für die Kommunikation und den Datenaustausch im Umfeld der Industrieautomation. Mithilfe von OPC UA werden sowohl der Transport von Machine-to-Machine-Daten als auch Schnittstellen und die Semantik von Daten beschrieben.
