It is calculated asfollows:Figure 4: Reaction Time for Connection between One <strong>HIMax</strong> and One HIMatrix ControllerTR = t1 + t2 + t3 + t4T RWorst Case Reaction Timet 1 <strong>Safety</strong> Time of PES 1t 2 0 ms, if Production Rate = 0 (normal case),otherwise ReceiveTMO + Watchdog Time of PES 1t 3 ReceiveTMOt 4 <strong>Safety</strong> Time of HIMatrix PES 2The worst case reaction time depends on the process and must be agreed upon togetherwith the test authority responsible for the final inspection.11.2.3 Calculating the Worst Case Reaction Time with two HIMatrix Controllers orRemote I/OsThe worst case reaction time TR is the time between a change on the sensor input signal(in) of the first HIMatrix PES or Remote I/O (e.g., F3 DIO 20/8 01) and a reaction in thecorresponding output (out) of the second HIMatrix PES or Remote I/O.
