Brief description
The block is responsible for the internal administration of the target positions. Semi-automatic
mode (SAM) is possible without this block. In this case, the targets must be specified by the
crane control system.
Method of operation
This block provides the target generator functionality. More detailed information can be found
in Chapter Target generator (Page 195).
Proper functioning is dependent on use of the DCC_SCTROLLEY and DCC_SCHOIST AddOn
DCC blocks as well.
Connections
The inputs of the DCC block are connected via unit-global variables of the MCC source file
"AddOn" to the outputs of the "FB_TargetsPLCToAddOn" block. The DCC block outputs are
interconnected with the inputs of the "FB_TargetsAddOnToPLC" block using unit-global
variables.
