I have a couple of machine types that make multiple parts per machine cycle. I have access to the starting pocket and ending pocket in macros from Kepserver.
Currently I have to use Kepserver advanced tags to “do the math” to get the number of parts produced. I.E.:
<ending pocket> - <starting pocket> + 1
If I had the expression editor in machine triggers, or at least access to basic math functions I could remove this dependency on Advanced Tags.
