Hi,

 

A site customer has requested a specific solution and I am having trouble working out how PI can allow me to give this to them.

 

Question

What method would you use to determine the sequence of event occurrences for a set of tags (e.g.) which tag changed to state = 1 first, then second, then third etc..... The event occurrences then need to be output to a visualisation or report either in ProcessBook or DataLink (e.g.) example format below, with each of the coloured boxes outputting the tag with an event occurrence.

 

 

I tried to use an IF ELSE statement, which works for the first condition but for subsequent conditions it gets complicated. Please help!!!
