This is to add a digital input such as an alarm signal from an analyser.
General Settings
Instrument
Select the Instrument from this dropdown list in order to select the parameter in the next field. This selection is effectively a filter.
Parameter
Choose the parameter you wish to record from the instrument. Where possible this list is pre-populated with known available channels.
If the desired parameter is not available set the channel to User Defined.
Label
The label for the new channel e.g. Switch State
Description
This is a free-text description field for use by the user and is not a required field.
Minimum Capture %
The Minimum Capture % describes the minimum amount of data Congrego® will accept to generate a valid average for a report.
The default value is 75% samples to create a valid average.
True Text
This field allows the user to define the result in a textual format if the digital bit is “ON” (non-zero)
False Text
This field allows users to define the result in a textual format if the digital bit is “OFF” (zero)
Enable Channel
Users can enable or disable the channel with this toggle switch without having to delete channels and instruments.
User Defined
Manually input the parameter ID or register to be logged and set the units and direction for the channel
User Defined Parameter
Advanced Setup
The advanced channel setup menu allows additional setting for each channel depending on instrument type.
Molecular Formula/Weight
Input the molecular weight for a gas channel. Congrego® can use this to perform automatic conversion from volumetric units to mass units.

Elevation
The elevation of the site in metres. This value is not used by Congrego® and is for reference only.
Processing Interval
When a processing interval is defined, Congrego® will apply aggregation to this period on the channel, on a dashboard widget or in a report.
In effect this turns the channel into a rolling average value representation, as opposed to the 'last' value, which is the default.
If this interval is not set, then Congrego® will use the latest parameter value on the dashboard, and the parent report's period for report values.
If the latest value and a rolling average value is required then the channel can be duplicated and the Processing Interval set in one.
High Alarm
Congrego® will display the channel status as High Alarm if the channel result is above the set value and the real time channel data display will change colour.
Additionally the data will be flagged as being in a High Alarm state.
Low Alarm
Congrego® will display the channel status as Low Alarm if the channel result is below the set value and the real time channel data display will change colour.
Additionally the data will be flagged as being in a Low Alarm state.
Minimum Value
Allows users to define a minimum value for a parameter below which the Minimum Value Override will be displayed
Minimum Value Override
Allows users to define the displayed result if the channel values is below the set Minimum Value
Maximum Value
Allows users to define a maximum value for a parameter above which the Maximum Value Override will be displayed
Maximum Value Override
Allows users to define the displayed result if the channel value is above the set Maximum Value
The Min/Max Value and Min/Max Value Override will cause the actual parameter value to be changed when it is out of range.
The logic applied is: If (value < MinValue) then value = MinValueOverride If (value > MaxValue) then value = MaxValueOverride |
Start-up Value
This value is used to prime the parameter value on start-up (first connect).
This is useful for setting analog outputs to a known state on start-up. As a safeguard for example, should the Calibration sequence run into issues when run and Congrego® has to be restarted, an analogue output that was set to a value during the sequence will be set back to this known value when the application restarts.
Note that this parameter is not applicable to all Channel types.
