AC800M OPC DA Data Quality goes down for sometime after download - 800xA 6.0.3-3
I am facing one issue in 800xA system 6.0.3-3 AC800M connect.
System is up & running; CBM is online; OPC DA quality is good and I am getting data on HMI.
However if i make any changes and download CBM again, OPC DA Quality goes bad for sometimes and getting good quality after some minutes.
Kindly advise how to resolve this issue.
The duration shall not be "minutes", rather "seconds" and may depend on if you perform cold or warm download and how large the application you download is.
Can you describe your download procedure & problem further?
Time with bad quality can be measured by having a Basic History log logging a property and use the "Log Configuration > Status > Read" function to read out the log as a table where time stamps and quality is very visible.
The time to come online with good data can be delayed if there is a problem for Control Builder M to upload the compilation results to its FSD server (you may have many, but only one is connected by each client node), propagation from FSD server to the FSD server used by your AC 800M OPC server(s) and finally, the reaction time for the AC 800M OPC server to "detect" the change of application serial number and the time it takes to download the compilation results and take them into use.
You should be observant on:
- system geometry (which FSD server your Control Builder M and AC 800M OPC servers sit at)
- diagnostic events in the [Workplace Structure]Web System Workplace:System Event List of 800xA
- events in the AC 800M OPC Server's session.log
Please add an answer to your own question having the data I pointed out.
