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_HoistPLCToAddOn" block. The DCC block outputs are
interconnected with the inputs of the "FB_HoistAddOnToPLC" block using unit-global variables.

Error messages
If an error occurs, output "BERROR" is set and the error number is output at output
"IERRORID" (for a description and help, see Chapter Error list AddOn (Page 374)). If several
errors are present, the oldest error will be displayed.
