Notes on creating recipes

Expansion in the "Properties of ..." dialog
For each recipe unit procedure (RUP), you can decide whether this will execute AS-based or
PC-based. You make this decision during recipe creation in the properties dialog of each recipe
unit procedure. Mixed operation within a recipe is permitted.
Mixed operation and blocks
Mixed operation means the option of using both modes, PC-based and AS-based, in one
recipe. This could, for example, mean that the recipe logic for a RUP is processed in the
automation system and for another RUP on the SIMATIC BATCH server.
This is only possible if you use the "UNIT_PLC" block from the supplied SIMATIC BATCH block
library in your PCS 7 project. With this block, both modes are possible. The "IUNIT_BLOCK"
block from previous versions of SIMATIC BATCH is only permitted for the PC-based mode
and it is interlocked against use in AS-based mode.
During batch control, the two blocks coordinate the allocation of individual units to the running
batches. One instance of one or other of these two blocks is required in one of the hierarchy
folder charts for each unit.
Options in mixed operation
You have the following options for mixed operation in a master recipe:
● Recipe in AS-based mode with the "UNIT_PLC" block
● Recipe in PC-based mode with the "UNIT_PLC" block
● Recipe in PC-based mode with the "IUNIT_BLOCK" block; only possible with a migrated
PCS 7 project since this block is not supplied in the SIMATIC BATCH block library.
● Recipe in mixed operation with the "UNIT_PLC" block
● Recipe in mixed operation with the "UNIT_PLC" and "IUNIT_BLOCK"; only possible with a
migrated PCS 7 project since this block is not supplied in the SIMATIC BATCH block library.
In the BATCH configuration dialog, prior to downloading, the validation function checks
whether or not the same "UNIT" block type is used within a unit class. Within a unit class, you
can work with either only "IUNIT_BLOCK" or only "UNIT_PLC". A mixture of the blocks within
a unit class is not permitted and is rejected during validation with an error.
Recipes with references to other units
General property of AS-based mode.
A reference is always executed within this AS in a unit. In this case, the BATCH server is not
involved. This means that no problems occur in the recipe execution and therefore your batch
