Display selection loading/unloading
Description
Display selection loading/unloading:
A check is made whether bit D 1.0 "Disable loading/unloading" is set at the user interface
DB 146/DW 1 to DW 5. If this is the case, the block stops execution and initiates the display of
an error message on the screen.
A check is made whether a valid number for the loading magazine is entered in the machine
data DB 146/DW 136 and whether the magazine is a fictitious magazine or not. If it is a
fictitious magazine, processing is aborted and display selection is disabled as no D no. is
assigned (in case of an error, error message and abort).
If no D number is entered in the reference list of the loading line (DW 2), an unassigned
D number is requested by the TO memory management and the loading line deleted.
NC and PLC pointers are initialized.
