Task
The "FB_TrolleyPLCToAddOn" block reads the input area from the PROFIBUS DP /
PROFINET PN for the Trolley block and separates the array into words and bits.
Connections
The outputs must be connected using unit-global variables of the "AddOn" MCC source file with
the inputs of the DCC_SCTROLLEY DCC block.
