n
Number of Memory bytes from MB0: Enter the number of retentive memory bytes
from memory byte 0 onwards.
n
Number of S7 Timers from T0: Enter the number of retentive S7 timers from T0
onwards. Each S7 timer occupies 2bytes.
n
Number of S7 Counters from C0: Enter the number of retentive S7 counter from C0
onwards.
n
Areas: This parameter is not supported.
n
Priority: Here the priorities are displayed, according to which the hardware interrupt
OBs are processed (hardware interrupt, time-delay interrupt, async. error interrupts).
n
Priority: Here the priorities may be specified according to which the time-of-day inter-
rupt is processed. With priority "0" the corresponding OB is deactivated.
n
Active: Activate the check box of the time-of-day interrupt OBs if these are to be auto-
matically started on complete restart.
n
Execution: Select how often the interrupts are to be triggered. Intervals ranging from
every minute to yearly are available. The intervals apply to the settings made for
start
date
and
time
.
n
Start date/time: Enter date and time of the first execution of the time-of-day interrupt.
n
Process image partition: This parameter is not supported.
n
Priority: Here the priorities may be specified according to which the corresponding
cyclic interrupt is processed. With priority "0" the corresponding interrupt is deacti-
vated.
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 inter-
rupt. 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 STOP: 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 diagnostics buffer (circular buffer).
n
Synchronization type: Here you specify whether clock should synchronize 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 compensated 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.
