Howdy,
I'm sending a large amount of data over some OPC arrays and other tags. At times, I've noticed some lag in the data and am trying to determine where it's happening.
Does this seem like a possible issue with OPC?
Would there be any good place to look to troubleshoot?
thanks
Start with many more details than you've provided.
Is this OPC UA? Another server? Are you reading large arrays from the server? Or writing large arrays to it? How large is large? What does "lag" mean in this context?
Thanks Kevin,
Yes, this is another OPC UA Server.
Yes, I have a 25,000 point array, and several others running at a fast rate.
I'm not writing arrays to it, mainly just sending some small data.
The lag means the 'real time' data is coming in late, but not missing any data.
I've been turning it over and while an OPC timeout might be contributing to the problem, I think the 'data jam' is happening in my programming upstream where it should normally real time process but if there are network or opc timeouts it might be contributing to it.
