I have never used FT View but I have a customer that is referencing a bunch of my AOI instances that are on their PLC. This is causing problems because I can't delete those instances while online because it says there is a client connected to them, which I assume is FT View. (I would delete those instances and then rename the new instances to the old names)
So to solve this problem in the future, My thought was to create another UDT that has the same member names, and then just create some code to copy my AOI outputs into that UDT that way if I need to update the AOI again it doesn't break the stuff on their HMI.
So while everything is offline can I change the type on those old AOI instances to the new UDT instance, and as long as all the names are the same except for the type name will FTView still read those tags ok, or will it get confused because the types changed?
I am basically trying to minimize or eliminate the need for the customer to change anything on their HMI.
Basically
Does that make sense?
