Good Morning,
Is there a log in the APROL-Web portal that records when Connectors have changed Value? Running, Stopped, Failed Etc.
How I have dealt with this in the past is using an alert block to trigger a message in the alert system, however this means having
an alert block for almost all the connectors. In a large system this becomes quite time consuming.
So my question is, is there a better way of doing this?
Any help or guidance would be great thankyou.
Dale.
Hello Dale,
By “Running, Stopped, Failed, ..” you mean actual values, not status flags of PVs.
As it is described here: Status PV - BR help
We are not logging all connectors or connections in the system, which are used in logic, and from a point of view, it doesn’t make sense; it could be thousands of values.
Only what is automatically logged by the system is Operator/User interaction (changed values in DC, or in debug mode of CaeManager), and this information is visible in the AuditTrail report.
To your solution, do you need to alarm it? For Failed value it makes sense, but for Running/Stopped?
For individual logging you can use PDA block, or trend block, depending if it is numeric or text values, and if it is discrete values or continuous values.
Both trend blocks can be found in APROL library, PDA (process data acquisition) can be created in your customer library.
Keep in mind, if you have repetitive logic, you can use HyperMacros or you can generate CFCs via SolutionGenerator/List Engineering.
