Response Time - Demand of the Safety Function
The safety response time of CR30 is the screw-to-screw response time to turn off
a safety output at demand of the safety function by the safety input device. The
safety response has to be calculated for each safety monitoring function. Ta b le 21
shows the possible safety chain with all considerable response times.
Table 21 - Safety Chain Response Times
Tab l e 22 shows the additional processing time of dedicated SMF
