I'm sorry to create a second topic regarding this; the previous topic is marked as 'answered', but maybe I did not gave enough information because the answers do not solve my specific problem.
What I want to do is store in one PI point an array of values of a spectrum and preferably display this spectrum using an OSISOFT tool: so an array of values each timestamp instead of only one value each timestamp in one PI point. This is because I receive a spectrum (array) from my PAT analyser instead of one value each timestamp.
F.e. instead at 7/26/2013 16:30:00 -> value: 14.3, I get at: 7/26/2013 16:30:00 -> 10 values:14.3, 20.8, 31.7, 12.4, 19.2, 20.3, 5.0, 4.0, 3.2, 0.1.
One possibility is to use several PI points (0%, 10%, 20%, ...100%) for a rough spectrum each timestamp, but this gives me not enough information or else I have to create too much PI points: the problem is that I have a spectrum that has multiple peaks. For sufficient distinction I need about 100 values in the array or about 100 PI points.
Another possibility is using one string point, and put all the values of the array in this string in CSV format, but then I do not have an easy way to display the spectrum. Maybe in XL and some VBA for parsing the string or with a PB add-in?.
Any other possibilities?
Thanks, Johan.
