The PROFIsafe module cyclically checks the returnedactual value of the output lines against the setpoints from the process image. If thesetpoint deviates from the actual value, the deviation is tolerated within the outputtolerance time.The output tolerance time is needed, for example, for adjustment when connectedto a load with capacitive character or in an environment characterized by heavyelectromagnetic interference.When the digital power outputs of the PROFIsafe I/O module are used to switchloads that have a low current consumption with a relatively large capacity, the"Short circuit to VCC" diagnostic can occur if the configurable output tolerancetime is set too short. In this case, the load capacity is not unloaded fast enough.Read section "Switching Capacitive Loads".The value of the Output tolerance time parameter must always be set to the sameor larger value than the value of the Test pulse duration parameter.Output tolerance time must be the same or greater than test pulse durationThe value of the Output tolerance time parameter must always be set to thesame or larger value than the value of the Test pulse duration parameter.Behavior of the PROFIsafe I/O module in the event of a failureIf an error is detected on a digital input or digital power output by the PROFIsafeI/O module, the entire PROFIsafe I/O module is passivated by the process imageof all digital inputs being set to "0" and all digital power outputs being switchedoff.For detailed information, read the section "Diagnostics".Use the same value for the output tolerance time of output O1 and O2!If the Output Configuration parameter is set to "H-Side/L-Side 1" or "H-Side/H-Side 1", the values of the Output tolerance time parameter for both outputs O1and O2 must be set to the same value. This is checked by the PROFIsafe I/Omodule during the parameterization procedure and a suggested correction isindicated by the PROFIsafe I/O module in the WAGO parameterization tool incase of deviation.
