Product introduction and installation
3.6 Configuration limits
Typical performance data for the two operating modes
The following quantity structure for AS-based mode represents a complex process cell.
Requirement for the AS: A recipe of the size shown below can be downloaded to and processed
for the recipe logic assuming that the AS has a work memory capacity of 30 MB, 60% of which
is being utilized.
Result: The following table specifies from a SIMATIC BATCH perspective how the automation
system can be configured taking into account the conditions listed above.
Automation system (AS)
Setpoints/parameters per RPH
48 setpoints/parameters per recipe phase with a maximum of 5 text
string setpoints/parameters and a maximum of 32 characters per
text string
RPHs per ROP
96 recipe phases and transitions (total quantity) per recipe operation
(ROP)
ROPs per RUP
20 recipe operations (ROPs) per recipe unit procedure (RUP)
RUPs per AS
16 units per AS with 48 setpoints/parameters per recipe phase
(RPH)
BATCH capacity limits
Number of batches that can run simultaneously in a batch process cell
Number of recipe phases (RPH) that can run simultaneously in a batch
Number of recipe phases that can run simultaneously in a batch process cell
Regardless of the data listed in the table above, in each AS a maximum of 100 recipe objects,
for example recipe operations, recipe phases and transitions, may change their status per
second. In this case, the time taken for recipe processing accounts for approximately 60 to
70% of the maximum automation system cycle load.
We recommend that you do not process more than 300 active recipe phases on a BATCH
server (nor a redundant server).
Note
Number of recipe phases running simultaneously
Depending on the frequency and how often step changes occur, the SIMATIC BATCH server
can process significantly more than 300 active equipment phases/operations.
Report creation and archiving
SIMATIC BATCH can process data (XML archive file) up a maximum of 200 MB in a report.
This applies only when using the XML format with SIMATIC BATCH version V7.0 or earlier.
With SIMATIC BATCH V7.0 SP1 or later, this restriction no longer applies to reports due to
the use of a new XML format.
