We are using Freelance connect 800xA 5.1 Rev-C. Log is not able to read the correct value from CBF Emulator.
We are using 800xA with Freeance Connect. CBF version in 9.2 Sp2. We have configured Logs for analog inputs in 800xA system. We could see that log is reading the data from OPC. But, what we could see that, when ever we change some value from CBF, Log is able store only one sample of that value. next sample that it could store is log value.
e.g. if force 20 from CBF log reads 20, when we force 40 next time, one sample that we could see in log is 40 and next sample that logs reads is again 20 continiously where as faceplate could show 40 on it.
The detail snap shots are attached herewith.
Has anybody experienced this kind of situation with freelance connect? Please provide your views on this.
Check few things,
- Are you sure the variable in CBF you have forced stays @ forced value for next few cycles ? you can check that by adding that variable in value window in cbf.
Because it may be possible in faceplate the last changed value stays where as in log actual values are getting logged i.e while you force value change to new value and then again return back to old one.
- as you are using emulator how you are forcing value ? is it via write or correct option ? or is it some internal variable you are wiring in online mode ?
- in CBF you can not write one variable from multiple source i.e the variable you are writing might be connected somewhere else but you are forcing by entering value and for that cycle it is accepting temporary value. ideally it should not be allowed but better you can check the variable via cross referencing if at all it's multiple write case.
