I have setup an audit profile, and enabled audit logging in the project, my only issue is we have some analog variables that are being logged about 10times a second due to changing values.
I would just like a way to disable logging for some of these 'nuisance' variables, or a way to limit their logging.
Ideally all we really want to log is when a user changes a variable from the SCADA interface.
If there is a way to do this, could someone please direct me to where I can read up on it?
Interesting.. Are the analog values in question being written from logic within the Vision project itself? Or are they simply values being read in from a PLC?
EDIT: I can imagine some situations where certain binding configurations might be trying to propagate writes back out to a tag and might end up in the audit profile.. In this case you might just need to adjust/correct things.. Normally the audit profile will capture just what you're wanting it to--values written/changed from a Vision client session.
The value is calculated in ignition from a table and then sent back to the PLC. Is there a way to stop logging of this tag?
Yeah it is writing to a tag in the PLC.
You mean a table in a user interface? If so, no, you can't stop it. That's exactly what it is supposed to capture.
Such continuous process tasks should be in a gateway timer event or other place independent of the UI. Clients do crash and/or get turned off, after all. Moving the process logic would make your system more robust and also get rid of the nuisance audit logs.
