Hello Community,
I’m hoping this is the right place.
I want to define an array with fixed boundaries in a datatypes sheet inside the Components window of the PLCnext Engineer. I know, that I can define constants inside this datatypes sheet with the keyword “VAR CONSTANT”, to use it as boundaries for my array. But these constants are only visible inside this Datatypes sheet. I also need these constants inside my programs and functionblocks. For this I defined an additional constant in the global data space, which holds exactly the same value, as the constant defined in the datatypes sheet.
Now my question:
Is it possible to define this global constant only once, somewhere where I could use in a program/functionblock as well as in a datatypes sheet?
