Robin P Posted September 12, 2014 Report Share Posted September 12, 2014 I would like the HMI user to monitor Trends from up to 100 similar input feeds - these are gas flow rates. I obviously have to define 100 Feeds, but if I were to put them all in the one Sampler and link the Trend graph to that Sampler then the user would have to step one-by-one through these Feeds to get to the one of interest, which is tedious. If I define a number of Samplers, each covering a different subset of the Feeds, then it seems I have to create for each of these a separate HMI screen each with a Trend widget linked to a different Sampler. Maintenance of such a set of HMI screens, keeping them alike, now becomes laborious. Is it possible to programmatically switch the Sampler or the Feeds associated with a Trend widget? If it were, then we could enable the user could do this via a single HMI to access the Trend of interest. Regards Robin Proctor Quote Link to comment Share on other sites More sharing options...
