Note
Number of PROFIBUS slaves
The content of the SDB2000 and related further SDBs is stored by the PLC operating system
in internal data structures, which the PROFIBUS ASIC can also access. Furthermore,
information from SDB2000 is also conditioned (CPI interface) and transmitted to the NCK
and the PLC basic program. This is necessary in order to control drives and PROFIsafe
modules on the PROFIBUS. A memory area defined by the PLC is available for these data
structures. Its size is limited by the maximum number of slots. This means that during
loading, SDBs with fewer slaves than listed above may be refused. A slot is usually a slave
module or the slave itself. Only on a module with both I and O areas does one module count
as 2 slots. It is, therefore, not possible to specify the size of SDB 2000 exactly. It cannot be
determined whether the configuration is legal until the SDB container has been loaded to the
CPU. The values shown above must be taken as guide values only. If the configuration is not
permissible, the alarm 410160 is set. If the configuration does not fit in the internal data
range, no PROFIsafe and no SFC 15 functions work.
PLC versions
• PLC 317-2DP release, based on SIMATIC version 2.1 (version ID 20.70.xx) is integrated.
• PLC 319-3PN/DP release, based on SIMATIC version 2.4 (version ID 24.90.xx) is integrated.
These versions are compatible with the corresponding SIMATIC CPU 300, which means that all modules and
software packages that are approved for these versions and CPUs on SIMATIC are, therefore, suitable.
Centralized I/O modules are the exception. The version ID in the version screen comprises the following:
• SIMATIC CPU PLC primary version identifier
• Internal increment
Version screen on HMI
In the version screen, the currently used PLC and the associated version of the PLC operating system are
displayed under PLC (e.g. PLC 317-2DP 20.70.40). In the column after that the module ID of the PLC module
used can be read.
The following PLC module codes are currently in use:
