7.4.5 Entries into the processing table
The93XXcontroller providesa certaintimeforcalculating theprocessing timeof FBs.Since thetype
and number of FBs to be used depends on the application and can vary strongly, not all available
FBsarepermanently calculated. Aprocessing tableis therefore provided undercode C0465,where
only the FBs used are listed. This means that the drive system is perfectly matched to the task. If
further function blocks are integrated into an existing configuration, these must be listed in the
processing table.
Several aspects must be observed:
The number of FBs to be processed is limited
Amaximum of 50FBs can be integrated into a configuration. Every FB requiresa certain processing
time.Code C0466 displays the residual time for the processing of FBs. If this time has elapsed no
further FBs can be integrated.
Entry sequence into the FBs
Normally, theentry sequence under C0465 is arbitrary, but it may be important for applications with
high response. In general, the most favourable sequence is adapted to the signal flow.
Example:
AND1

AND1-IN1
AND1-IN2
AND1-IN3
AND1-OUT

C0821/2

Fig. 7-5 Example of a configuration
Struction of the processing table for the configuration example in Fig. 7-5:
1. DIGIN need not to be entered into the processing table.
2. First FB is AND1, since it gets its input signals from DIGIN and is only connected to
successors.
3. Second FB is OR1, since its signal source is the output of AND1 (predecessor). The output
signal in AND1 must be generated before being processed in OR1. At the same time OR1 has
a successor. OR1 must therefore be entered into the processing table before its successor.
4. Third FB is AND2, since it has a predecessor (see 3.)
