Hi all,
we have a OSIPi OPC Interface running collecting data in "advise" (If the value changes, the OPC sends an update of the value) mode from our DeltaV OPC Server. For some tags we are not receiving value updates. Is there a way to observe the outgoing traffic from the OPC Server to Pi-Node? I was thinking in a log file or something similar in order to check that the OPC is definitely sending the update. Because in the OSIPi Interface log i can´t see an update for the value.
If i request the value with OPC-Remote Tool i can see the updated value, therefore i think there could be a problem with the OPC "sending" the value update. Same if the tag is switched to "polled" (a request to the OPC Server to send an update), i can see the updated value. For Performance reasons i want to use the first explained "advice"- mode.
Greetings
Tobias
