The HMI matrix in BLX needs to be created after importing the solutions generated from the engineering tool.
The Image below illustrated the concept of having the flow of the process going from left to the right and the Details of each process going from the top and down.
The matrix is buildt by dragging the mimics in the area to the left of the matrix into the right place in the matrix.
Normal process flow is:
Feeders --> online --> Mill --> Lab --> Silo
