This is actually a Techsupport question, and you could call Techsupport line to get help. In general, vCampus team should transfer this issue to Techsupport team. As this is a easy question, I will give you answer here. However, if you have the similiar questions, it should be better to call OSIsoft Techsupport team.
Point Source "C" means this PI tag is a PE (Performance Equation) tag. Therefore, you could only choose Natural trigger (when tag1 has new value, tag 2 will do the calculation) or Time trigger (calculation based on the fixed time, like 2 seconds, 1 minute). This needs to configure the PE interface. If you need to know some details about Time trigger, please call OSIsoft Techsupport team.
Regarding to your question, if you just use "Natual" trigger, it is not necessary to configure location1 to 5. If you use "Time" trigger, location 4 is the only one need to be set. The setting is same as the general PI Interface. For example, after you configured the scan frequency for PE interface, you just need to put the matched number of the scan frequency in location 4. The details, please call OSIsoft Techsupport team.
Hello Thanks for your answer.This works for me
another quest is:
do i need to multiply excp deviation and compression deviation by the the same factor that multiplied the tag values.in my example below do i have to multiply excp deviation and compression deviation by 2
I will transfer this thread to OSIsoft Technical Support.
