Hello everybody !
I use a TP1500 Comfort Panel configured in TIA v.15.1 .
There are about 30 tags (based on analog signals) which the panel gets from a S7-300 PLC.
There is a task to make a value filter for every of those 30 tags. Filter must allow to pass through the value if the one changes more than “plus-minus” “dead band”. After that event the filter must remember the “last changed value” (LChV) and must continue to evaluate the current input value until it changes more than “LChV” “plus-minus” “dead band”. And so on.
1. Is it possible to make it in the Panel with ANSI-C script or with VBS-script only?
2. Will the script(s) “overload” the WinCC RT and the panel become “breaking” ?
3. Which triggers should be used to start the script(s) if it is necessary to check if the value changes more than “plus-minus” “dead band” every 2..3 seconds.
I know the task it is possible to realize in STEP7 but first I want to try it in the panel cause I think it will take much less efforts.
Thanks in Advance.
