n Priority:
Here the priorities may be specified according to which the corre-
sponding cyclic interrupt is processed. With priority "0" the corre-
sponding interrupt is deactivated.
n Execution:
Enter the time intervals in ms, in which the watchdog interrupt
OBs should be processed. The start time for the clock is when the
operating mode switch is moved from STOP to RUN.
n Phase offset:
Enter the delay time in ms for current execution for the watch dog
interrupt. This should be performed if several watchdog interrupts
are enabled. Phase offset allows to distribute processing time for
watchdog interrupts across the cycle.
n Process image partition:
This parameter is not supported.
n Level of protection:
Here 1 of 3 protection levels may be set to protect the CPU from
unauthorized access.
– Protection level 1 (default setting):
No password adjustable, no restrictions
– Protection level 2 with password:
Authorized users: read and write access
Unauthorized user: read access only
– Protection level 3:
Authorized users: read and write access
Unauthorized user: no read and write access
5.9 Setting VIPA specific CPU parameters
5.9.1
Proceeding
Except of the VIPA specific CPU parameters the CPU parametriza-
tion takes place in the parameter dialog of the CPU 313C-2DP from
Siemens. With installing of the SPEEDBUS.GSD the VIPA specific
parameters may be set during hardware configuration. Here the fol-
lowing parameters may be accessed:
n Function RS485 X3 (PtP, Synchronization between DP master
and CPU)
n Token Watch
Since the VIPA specific CPU parameters may be set, the installation
of the SPEEDBUS.GSD from VIPA in the hardware catalog is neces-
sary. The CPU may be configured in a PROFIBUS master system
and the appropriate parameters may be set after installation.
