Trend is not generating, Property field its showing OUT & In.IOValue, LogName field its showing TRIM
I have recently created new AI-Signal & when I am opening its Trend display it is not showing any graph. Other fields are fine except the fields given below:
1. PROPERTY FIELD: OUT & In.IOValue
2. LOG NAME: TRIM
Even though after opening the Trend display from its AI-Signal faceplate if I am changing the PROPERTY FIELD to: In.Value and LOG NAME FIELD to: SEAMLESS save option is disabled and I am unable to save any changes. Again after closing and re-opening same repeats i.e.PROPERTY FIELD: OUT & In.IOValue.LOG NAME: TRIM. and graph is not generated.
I have tried to change its Trend Template but that is disabled.
can any one help me out.
You can't change the default trend display & its properties of the trend display of the system libraries faceplates are reserved hence you are not getting any save button enable option.
If you want to use the trend display other than trim curve(showing instant value when u open the faceplate) then follow belo things:
1.create log template depending on your sytem architecture like if you are having conenctivity server then you can't create hierarchical logs means only primary logs you can configure ensure if AS+CS combined limit of primary logs=1500, if separate CS=10000 logs. create in lib str.
2.create trend template if you want to use ur own trend template in the lib str.
3.ensure history source aspect is defined at the top level(root) in controller str which should refer the basic history service group of connectivity server.
4.create the log configuration aspect for the control str object instead creating in the object type str for the signals you need history
5.Kindly don't copy/paste the log configuration aspect it will inherit the old log properties
6.Create trend display in the Functional str & link your trend template via config view to make your customised trend display.
