OPC-UA on S7-1513 Issue "Reading archive values from OPC server failed! Access Denied (E_AccessDenied)"|OPC UA Standard|Forum|OPC Foundation

Hi,

i have some issues with the OPC-UA server.

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?
