Using Array and Structure Elements for Data Exchange

You can use array and structure elements for data exchange between the controller

side (SoMachine) and the HMI side (Vijeo-Designer). However, you cannot

exchange whole arrays and structures at once.

For example:

z If A is an array, you can exchange an element of the array

(A[0],A[1],...,A[i]) but not the entire array.

z The same rule applies to structure element, you can exchange an element of the

structure (StructureName.ElementName) but not the entire structure.
