4.9.3 Batch Control with Barcode Reader
If a barcode reader is connected to the interface “RS232 for barcode reader”
(connector 2) or “RS232/RS485” (connector 7), then the batch start, batch
stop, and input of batch texts in a current batch report, can be controlled by
the barcode reader. The bar codes that are used all correspond to the type
“Code39”.
Preconditions - The interface must be configured for bar code operation.
Example:

- The batch start (= batch stop) must be configured.

Before entering commands through a barcode reader, the
corresponding batch/plant 1 — 3 must be prepared by scanning in
“BATCH1 — 3” for the bar code commands, regardless of whether
or not they are automatically displayed.
