Hi. So this is my first project with FT View SE coming from the WW world and it has been more than a little frustrating. Programming is not an issue with me although I may be a bit rusty as I have not done it in some time. I tried to find answers to my questions and did find a lot of them here and in RA's KB but some I have not been able to find or sort out.
The HMI has a requirement to do significant lookups on data that is stored in the PLC. There are product profiles of some significant size including strings, ints, and bools. There could be up to 60 registers storing these and I need to consistently refer to them on several displays throughout the HMI. So I am consistently searching them, reading them, updating the tags, and so.
I have a "header" display always loaded so I have been trying to populate tags groups in the header's display load. I have figured out how to call public subs from this header display but I cannot seem to do the same with the tag groups. Is there no way to create "application level" tag groups to be used across displays so only one is in memory versus making one on each display? I keep thinking I am missing something really simple but I just can't seem to get it to work.
Sorry for all the typing....
