OPC Server for AC 800M how do I prove that all OPC items are updated at least every second?
We have requirement regarding all values in the 800xA system coming from the AC800M must be updated at least every second.
I have searched for answers in the window “OPC Server for AC 800M” -> Help -> Manuals and also in the same window help->contents.
I think I understand how “items” are put in to different “uprate rate groups” in the OPC Server
The slowest task used in AC800M controllers are 1000ms.
In the window “Update rate” update interval for the groups in the OPC Server is default -> 500, 2000, 5000, 10000, 30000 all ms. In the same window we can see that 500 and 2000 ms are in use. Opening another window “OPC statistics – Data access” we see a group with update rate 3000ms number of items is not constant but so far 24 items are the maximum we have seen.
I am aware of the Items can be located in 2 groups.
Is it possible to find the names of the Items that is only updated every 2000ms or 3000ms depending which window I look in?
Is there a better way to prove that all OPC items are updated at least every second using AppLogviewer or other diagnostic tools?
