p9658 SI transition time STOP F to STOP A (Control Unit)
Sets the transition time from STOP F to STOP A on the Control Unit.
For a crosswise data comparison between p9658 and p9858, a difference of
one safety monitoring clock cycle is tolerated. The parameterized time is inter-
nally rounded-off to an integer multiple of the monitoring clock cycle.
STOP F: Defect in a monitoring channel (error in the crosswise data compari-
son)
STOP A: Pulse cancellation via the safety shutdown path
Units: Default value:
ms 0
p9659 SI forced checking procedure, timer
Sets the time to carry-out the dynamic update and testing the safety shutdown
paths (forced checking procedure).
Within the parameterized time, safe standstill must have been de-selected at
least once. The monitoring time is reset each time that SH is de-selected.
Units: Default value:
h 8
Within the parameterized time grid, the user must subject the safety shutdown
paths to a forced checking procedure and test them; this means he must carry-out
an SH selection/de-selection. If the user does not do this, then after this time using
the Alarm A01699 ("SI CU: Necessary to test the shutdown paths") he will be re-
quested to test the shutdown paths, i.e. select/de-select SH. In so doing, r9773, bit
31 is set to 1.
