Requirements on Sensors for Failsafe Digital Inputs
Please refer to section 18.8.
How to Program Onboard Digital Inputs in DB1
The parameters of the onboard DIs are programmed in DB1. In the basic setting (default) all failsafe
onboard DIs are assigned short discrepancy times. You can change this parameter in DB 1 with
COM 95F
The discrepancy time of the onboard DIs can be specified as
•
Short discrepancy time (approx. 1 ms)
•
Discrepancy time in n OB1 cycles
•
Discrepancy time in n OB13 cycles
