I have 2 tags from the PLC I would like to "trend." I do not want to trend each of these 2 tags. I only want to trend when both are on or have some desired value.
For example, if I have 2 valves, one numbered 20 and the other numbered 21, I want to trend the number of Valve 20 when both are in the divert position. When both of the PLC tags have a certain value, I want to "turn on" another tag (internal to the HMI). How can I create a tag internal to the HMI? Is there a dialog box that I can use or do I have to write a script? If I have to write a script, could I get some examples? I have never used Intellution before.
ANY help would be truly appreciated!!
Please help!
Thank you!
