Introducing the operating modes "AS-based" and "PC-based"

New BATCH block for both operating modes
When you create the master recipes, you can specify whether or not they are processed AS-
based or a PC-based for each recipe unit procedure (RUP). This is only possible if the new
block "UNIT_PLC" from supplied block library is configured in the relevant RUP.
What makes the AS-based operating mode possible?
The AS-based mode can only be implemented by using the new unit block "UNIT_PLC". With
the new AS-based mode, you can influence recipes being processed on the AS using the
UNIT_PLC block.
Note
Units with more than one AS
AS-based operation is not possible in units that have more than one AS on which the equipment
phases/operations are configured. In projects with such units, the AS-based operating mode
must be disabled in the BATCH configuration dialog (0% memory allocation).
Which functions are not supported in the AS-based operating mode?
● Flat recipes are not available.
● The "online structure changes (OSC)" from SIMATIC BATCH version 7.1 SP1 with which
structure changes could be made to the recipe logic during the running of a batch is not
possible in AS-based mode.
Memory requirements of the CPU and runtimes in AS-based mode

BATCH blocks in the AS-based mode.
