Kalle Hello, What type of CPU you are programming for?Normally you can define a same structure in a global DB or in temporary area of calling function(or OB) and assign it to the input of the mentioned function. Hope that helps Hamid Hosseini

If you use the AT overlay for your interface, you can define the same input multiple ways. For example, 32-bools, 2-words, 4-bytes If you create a custom plc datatype, you may still want to define it as InOut, but that may make it easier to deal with.
