If input monitoring is deactivated, the substitute value "0" is transferred. The channel is not
passivated.
If required, the AS-i slave can be monitored by another evaluation module, e.g., by another
F-CM AS-i Safety ST module, the 3RK3 Modular Safety System. This applies both when
input monitoring is deactivated and when it is activated.
Note
Call of the AS-i slave
The AS-i slave must be called by the AS-i master. Set up the configuration of the
AS-i master in such a way that the communication of the AS-i master with the AS-i address
functions properly.
Note
Slave profile
A safe AS-i input slave has the slave profile (IO.ID) = 0.B or 7.B.
I address
The input bit address of the input channel for the signal processing in the safety program is
indicated here. It is calculated automatically from the start of the inputs entered on the
"Addresses" tab.
Input delay
To suppress coupled-in interference or brief switching pulses, you can set an input delay for
each AS-i slave. This will suppress interference pulses whose pulse time is less than the set
input delay, in ms. The input delay applies to both channels of the channel pair of the AS-
i slave.
Note
Time of fault suppression shortened by up to 75 ms
It can take 15 AS-i cycles until the valid code sequence is detected. As a result, the time of
the fault suppression is shortened by up to 75 ms compared to the set value.
A long input delay suppresses longer interference pulses but results in a longer response
time.
Range of values:
Default
The values 0, 50 to 150 ms can be selected in 10 ms increments.
The input delay time acts in addition to the system response time. Suppressed interference
pulses are not visible in the safety program.
