Replacement value : This is used in the event of a input or output failure (refer also
to Status monitoring ). The settings depend on the channel type. For example,
digital inputs only have the options Off and On.
Force substitute value (simulation) : Sets the channel's output value to the given
substitute value. This setting is useful during installation to simulate certain con-
ditions or activate system responses.
Do not forget to disable the option for normal operation!
Inherited validity range (not available for all channel types): Enter the valid range
in which measurement values are valid.
Depending on the channel type, the validity range can be optionally inherited. If
the validity range can be inherited, the validity will be adopted, depending on the
channel type, either from scaling (see
Main settings tab) or the data source of the
channel.
The validity range is also used for displaying percentage trend, the percentage
data reduction and for displaying certain visual elements.
Data reduction (not available for all channel types): A signal is fed through the
channel input, processed within the channel and then released at the channel out-
put. The tolerance specifies the extent of change a signal must undergo following
processing before being output. The
Data reduction function prevents the device
from having to process/store superfluous data. The Data reduction function pre-
vents the device from having to process/store superfluous data.
The tolerance value can be expressed as an absolute measurement unit or as a rel-
ative value in relation to the
validity range .
Some channel types do not have a validity range and, therefore, you can only give
the tolerance value as an absolute measurement unit of the channel.
Formatting (not available for all channel types): Here the resolution for the chan-
nel’s values can be set.
Persistence (not available for all channel types): The currently valid output value
(refer to data reduction) is stored to a non-volatile memory. The channel uses this
value following a restart or power outage. This function is particularly important
for outputs in order to establish a defined state following power outage.
4.4.2 Sensor compensation tab
In this tab you can specify corrections for sensors. Conversion takes place accord-
ing to scaling settings in the
Main settings tab for the signal delivered by the
sensor.
