I put together an EZ Touch panel program with the Default Tag Data Type as UNSIGNED_INT_16. Now I need to change several Numeric Entry Tags to BCD_INT_16. When I try to edit this Tag the box is gray with no options. What is the best way to change the tags other than deleting and starting new.

What I have done - though it's a pain - is change the name of the original tag. Then create a new tag with the original name and the correct data type. The transfer each control's tag to this new one.
Example
TEST1 was created with UNSIGNED_INT_16
In the Tag Editor change the name to TEST1A
You'll notice that in the control(s) which use(s) this tag the name is changed.
In the Tag Editor make a new tage TEST1 with BCD_INT_16 pointing to the same PLC reference.
Now, go to each control and select the TEST1 tag instead of the TEST1A tag.

How do I get rid of the old Tags?

Once completely done, in the Tag Editor make sure that 'Highlight Unused Tags ' is checked. Review the 'unused tags ' then press the 'delete Unused Tags ' button.

I did this but there are no unused tags highlighted. When I do a Tag Cross Reference on a given tag there could be as many as 32 objects linked. How do I break this link and make the old tags unused? I went to every screen where a given tag was used and edited it for the new information and still can't rid the old tags. It looks like I'll have to start over.

I had fun tracking everywhere I referred to a tag. I had used them in 'visibility ', in the references for 'Up ' and 'down ' buttons, all sorts of places. Only when I had changed every one could I delete the old reference.

There is a feature in the Setup Menu called Tag Cross Reference, where you can select one of your tags and it will show you all the screens that tag is used on. This is very helpful for this type of operation.

Gentlemen,
I want to thank you for all the help on the Tag Type Change problem I developed. Believe me; I'll never make that mistake again. It was quite the learning experience. Even more, this was a very tedious and time consuming exercise.
