(c) Calculation example for the maximum value of response time
1) In synchronous mode
DT1 + DT2 + Safety remote station input response time + Safety data
monitoring time + Safety remote station output response time
= DT1 + DT2 + 12.2 + 80 + 10.4
= 102.6 [ms]
2) In asynchronous mode
DT1 + DT2 + Safety remote station input response time + Safety data
monitoring time + Safety remote station output response time
= DT1 + DT2 + 12.2 + 82.8 + 10.4
= 105.4 [ms]
