Attribute Value Description
In the state of missing output data, the set
-32767 ... 0 substitute value is output on the respective output
... 32767 channel with the set substitute value behavior
"Output substitute value".
Attribute Value Description
If the analog output module provides diagnostic
0 (false) data, the following attributes can also be set
channel-by-channel during parameterization.
If the analog output module provides diagnostic
1 (true) data, the following attributes can also be set
channel-by-channel during parameterization.
Attribute Value Description
A short circuit on the respective signal channel
does not lead to transmission of a diagnostic alarm
0 (false)
nor to entry in the diagnostics database of the
station proxy.
A short circuit on the respective signal channel
leads to transmission of a diagnostic alarm. The
1 (true)
respective error leads to an entry in the diagnostics
database of the station proxy.
Attribute Value Description
A low voltage on the respective signal channel
does not lead to transmission of a diagnostic alarm
0 (false)
nor entry in the diagnostics database of the station
proxy.
A low voltage on the respective signal channel
leads to transmission of a diagnostic alarm. The
1 (true)
respective error leads to an entry in the diagnostics
database of the station proxy.
