Hi Gang,
Haven't been by in many moons. Too busy.
I have run across an issue I cannot resolve. I have an application that was installed in the spring, so recent software versions. I have a Rockwell FactoryTalk Historian, and a FactoryTalk SE (distributed) server. I am collecting data from a 3rd party and displaying it and historizing it too.
I have a performance equation running in the Historian that selects the highest value from a set of tags, and the averages the highest value. I want to display the result in SE, but cannot seem to do it. I have tried {FTHistorian::Mytag} which SE says is valid, but nothing displays.
In the short term, I have embedded a small 2 x 3 Trend in the graphic, which shows the tag historical and current value. But it's not ideal.
Thanks,
Ken M.
