WARNING!
For 1-channel usage of safe digital outputs the response time during a fault
is increased by 16 ms.
Calculation formula
For calculation of a response time in case of different FSoE watchdog the
following formula is available:
t
React,std
Response time accoring to table above
t
wd
Configured watchdog time
t
wd,std
Watchdog time, refering to response time of table above
One FSoE connection:
t
React,wd
= t
React,std
+ 2 * (t
wd
- t
wd,std
)
Two FSoE connections:
t
React,wd
= t
React,std
+ 3 * (t
wd
- t
wd,std
)
