n Update OB1 process image cyclically: This parameter is not rele-
vant.
n Scan cycle monitoring time: Here the scan cycle monitoring time
in milliseconds may be set. If the scan cycle time exceeds the
scan cycle monitoring time, the CPU enters the ST
OP mode.
Possible reasons for exceeding the time are:
– Communication processes
– a series of interrupt events
– an error in the CPU program
n Minimum scan cycle time: This parameter is not relevant.
n Scan cycle load from Communication: This parameter is not rele-
vant.
n Size of the process image input/output area: Here the size of the
process image max. 2048 for the input/output periphery may be
fixed.
n OB85 call up at I/O access error: The preset reaction of the CPU
may be changed to an I/O access error that occurs during the
update of the process image by the system. The VIPA CPU is
preset such that OB 85 is not called if an I/O access error occurs
and no entry is made in the diagnostic buffer either.
n Clock memory: Activate the check box if you want to use clock
memory and enter the number of the memory byte.
The selected memory byte cannot be used for tempo-
rary data storage.
n Number of Memory bytes from MB0: Enter the number of retentive
memory bytes from memory byte 0 onwards.
n Number of S7 T
imers 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 interrupt is processed. With priority "0" the corre-
sponding OB is deactivated.
n Active: Activate the check box of the time-of-day interrupt OBs if
these are to be automatically 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.
