Description
43302
Logical device for a safe sensor with 2 contacts/channels acting independently of each other
SF_IN_ASi_independent detects switching states of the two signal channels/contacts of a safe AS-i
slave (ASi_SlaveAdr, ASi_Master). The logical device forms the logical AND connector from the two
values and provides the result as safe control signal. The following additional conditions apply for the
logical signal evaluation:
The simultaneity of the signal change is not monitored.
If the signal state of the two channels is invalid longer than the firmly set time, both signal
channels have to take the state FALSE simultaneously before switch-on is possible again.
(InvalidTime = const. = 2000ms)
The programmer can activate the following functions as option:
DisableLogging:
Only error events are transmitted to the online support centre (OSC) of the AC4S user interface.
StartupTest:
Both signal channels must take the state FALSE simultaneously before the logical device can start
with the signal evaluation.
To reset the logical device from the locked error state and to read diagnostic information of the
logical device:
