Batch Cdv - Siemens SIMATIC BATCH Operating Manual

Generating the control recipe
Once a batch has been started in the BatchCC or on the PCS 7 OS, the BCS allocates the
unit on the AS, generates the associated control recipe, and sends it to the AS.
Downloading the control recipe to the automation system
The complete control recipe for one unit is loaded in a permanently assigned data block on
the AS using S7 communication.
All of the step and recipe structure data is stored in the data block.
Processing the recipe synchronization
If a synchronization line is reached during execution of a control recipe, the automation system
sends a frame to the BCS. In addition to the batch ID, the frame also contains the
synchronization number that is unique within a recipe.
A signal is sent to the AS when all units involved in synchronization reach the synchronization
line. The batch execution is then resumed simultaneously in all units.
Generating messages on the server status
The BATCH Control Server generates status messages for the BatchCC and the AS link. The
messages are stored along with the corresponding message numbers in PCS 7 Alarm Logging.
Generating the batch report
After a batch is started, the batch data is saved in the online data storage of SIMATIC BATCH.
In order to display and/or print out batch data, a print preview window and the batch report are
available.
Checking state of process cells in the event of a problem in the automation system
In the event of a problem in the AS (AS in STOP), the active automation functions go into error
mode. Depending on the setting under Properties > "AS operating parameters" tab under "SFC
start-up after CPU restart", the SFC / SFC type is automatically reset or retains its state.
Operator intervention is needed in both cases. We would only recommend a restart or
resumption of the function once the state of the process cells has been checked.
