Hi,

I’m not sure whether this is an issue of prosys server or the mentioned node-red node. What I get with the combination of https://flows.nodered.org/node…..trib-opcua and prosys server is the following:

– at the server I set variable update (sinus) to 200 ms
– at node red I set the variable interval to 500 ms and the client notification interval to 2 sec
– after starting the workflow I get every 2 seconds 4 totally identical values, i.e. not only values but also timestamps
– if I don’t set the variable interval, I get 10 fully identical values

I expected to get 4 or 10 values but not identical since the server updates the values more frequently.

So my final question is: Is the server able to send a batch of 4 different values every 2 seconds – and the bug is in the opc-ua node of node red – or does the server only send one value every 2 seconds – and the bug is again in the node-red node – or does the server send 4 identical values every 2 seconds – and the bug/restriction is in the server?
