Buffer assignment
Description
FB 170 initializes the display "Buffer assignment" with the display parameters.
The block operates in cyclic mode while this display is selected. The machine data are
determined and checked by means of the machine data "Magazine number loading point"
(DB 146, DW 136).
The locator number entered in DW 76 of the channel DB is offset against the machine data
"Offset loading point" (DB 146, DW 137) and, as a result, the data for change and loading
point displayed. They are therefore continuously updated in the display as the chain rotates.
If an error is found, processing of the block is interrupted and a corresponding interactive text
displayed.
