Issue OPC UA

Post by syconn »

Hi,

First: In the OPC-Client, variables have the status (Status= Testing if the accsess path is correct/connected). If the test was successfully status = “good” If not status = “not connected” or “Error”. Issue: some variables goes from “good” to “error” or “not connected”, it changes like every second.

OPC-UA Log says: 2018.03.06 18:43:43.073 6588 (0x000019BC) Error ot\foundationclient.cpp(1964) Monitored item was not created. Server status. opc-ua status: 2161836032

OPC-UA Client Log says: “Reading archive values from OPC server failed! Access Denied (E_AccessDenied)” and “COPCUAClientMonitoredItem::onError(): (PEID 1749): BadTooManyMonitoredItems”

Is there a limit how any MonitoredItem are allowed at the same time? its possible to change the limit?

OPC-UA Server is PLC S7-1513.

Hi,

Your post is somehow confusing since you are referring to a lot of things that have nothing to do with OPC UA and are client API specific error codes and names.

But BadTooManyMonitoredItems clearly indicates that you added more monitored items to a subscription than supported by the server.
