we are working with processbook to display a X-Y trend.
The values come from a DeltaV station, these are OPCHDA data.
There's no PI server, but a PI Protocol Converter.
When displaying a X-Y trend with 2 hours history, and 8 pen it takes about 8 minutes to display the trend.
We want to be able to add/remove pen, but because of the time it takes it is nearly impossible (too slow).
Would there be a workaround, or maybe a new version of processook is able to display X-Y trend faster ?
Processbook version : 220.127.116.11
PI Protocol converter version : not found (?)
PI OPCHDActr version : 18.104.22.168
PI SDK : 22.214.171.1241
PI Converter Data Engine : 126.96.36.199
PI Protocol converter APS Connector (piPCAPSCtr) : 188.8.131.52
We have several ways to display a X-Y trend :
...and actually we don’t know which one to use, each having advantages and disadvantages.
Would you have some advices ?
