When deleting and reinserting, something has been lost in the mappview binding.
There does not appear to be any notable differences, however when I try to rebind the values, the “select variable” window cannot locate go into the array.
Alternatively, you can right-click on the variable and select Automatic Enable → Recursive.
If you are using an Automation Studio version earlier than 4.12, you instead have to Right Click → Enable Tag and then turn on “Show array elements” from the Properties window:
Great this was the solution! however I would just like to have something clarified.
I enabled HMI as recursive. I made the assumption that everything within HMI would be enabled with the same setting, but does not appear to be the case. I needed to manually go to the array and set it as recursive. Is this a feature of the program or a bug as it seems to just add an extra step in my process for every array I want to work with.
structure elements of type “array of basic data type” are excluded even when using “recursive”.
This is a wanted behavior to avoid (too) long response time from the editor and also to avoid to (accidently) enable (too) many tags (=array elements), that are not really needed to be accessed by OPC UA (for example, arrays of simple datatypes are often used as “buffer / temporary memory only”).
For those reasons, such structure elements always have to be explicitly enabled by the user.
