Response times > Variable runtimes for single errors
Times to be considered
Max. response time for any
run time at one error
5.12.3 Variable runtimes for single errors
At variable run times of the standard system in addition to an existing error
, it is assumed
that the values of all the relevant run times are nearby the limit of the monitored times.
■ The max. processing time to and in the safety SDI:
(TI
ST
+ TI
DIS
+ TI
WCDT
+ TI
FSoEWD
)
■ The smallest of the possible monitoring times, from this moment the defined behaviour
of an error takes ef
fect:
(MIN (TI
FSoEWD
, T
CL_MAX
, TO
FSoEWD
))
■ The max. processing time to and in the safety SDO:
(T
O
WCDT
+ TO
FSoEWD
)
■ The possibly increased processing times in case of an error within the safety modules,
here only the larger of them, because it is assumed that there is a single error:
(MAX ((TI
OFDT
- TI
WCDT
), (T
O
OFDT
- TO
WCDT
)))
■ For the entire process chain a good FSoE telegram could be sent just before to the
safety SDI or SDO. Here the largest of the two timeouts must be considered:
(MAX (TI
FSoEWD
, T
O
FSoEWD
))
