Group parameters for the digital part

Name	Value	Internal Value	Internal Value, type	Default
Input delay	0.1 ms 1 ms 8 ms 32 ms	0 1 2 3	BYTE	0.1 ms 0x00
Detect short circuit at outputs	Off On	0 1	BYTE	On 0x01
Behaviour DO at comm. error *)	Off Last value Last value 5 sec Last value 10 sec Substitute value Substitute value 5 sec Substitute value 10 sec	0 1 6 11 2 7 12	BYTE	Off 0x00
Substitute value at output	0 … 255	00h … FFh	BYTE	0 0x0000
Detect voltage overflow at outputs **)	Off On	0 1	BYTE	On 0x01
*) The parameters Behaviour DO at comm. error is only analyzed if the Failsafe-mode is ON. **) The status “externally voltage detected” appears, if the output of a channel DC0..DC7 should be switched on while an externally voltage is connected PROFINETâ IO Bus Module CI501-PNIO (V3). In this case the start up is disabled, as long as the externally voltage is connected. The monitoring of this state and the resulting diagnosis message can be disabled by setting the parameters to “OFF”.
