n Priority: Here the priorities may be specified according to which
the corresponding cyclic interrupt is processed. With priority "0"
the corresponding 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 ST
OP 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 Report cause of ST
OP: Activate this parameter, if the CPU should
report the cause of STOP to PG respectively OP on transition to
STOP.
n Number of messages in the diagnostics buffer: Here the number
of diagnostics are displayed, which may be stored in the diagnos-
tics buffer (circular buffer).
n Synchronization type: Here you specify whether clock should syn-
chronize other clocks or not.
– as slave: The clock is synchronized by another clock.
– as master: The clock synchronizes other clocks as master.
– none: There is no synchronization
n Time interval: Time intervals within which the synchronization is to
be carried out.
n Correction factor: Lose or gain in the clock time may be compen-
sated within a 24 hour period by means of the correction factor in
ms. If the clock is 1s slow after 24 hours, you have to specify a
correction factor of "+1000" ms.
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
5.8.3 Parameters for DP
