Greetings, first post ever.
I'm new to PLC's, long history of electronics maintenance (Radars), and two years of Instrumentation experience. I understand the concepts involved with what I'm doing, but still learning the ropes. So here is my problem.
I have an already established system using wonderware. The operators have asked me to finish a screen that someone else started, giving them the ability to look at all the inputs from two separate TotalFlow devices on the platform. 7 of the 9 devices associated with these TF's are working, so I only have 2 that I have to get working. Each device has 10 variables assigned to them.
So, here is my problem. I know the access name, node, application, and Topic Name associated with the inputs coming from the TF's. I also, through the use of Historian, figured out the register number for each specific I/O point that I need. I have assigned all of this information to the tag, using the Tag Dictionary. I then assigned that tag to the appropriate animation. I saved everything, received no errors. Closed out WindowMaker, opened WindowViewer, and no. I consistently get zeros for every tag I created.
I've compared my tags to the previously existing tags and everything looks identical other than the specific address for each I/O point. I really don't know what I may be missing, but I'm assuming that there is some final step in the process that I am not seeing. So....
Help?!?
