The Psuedo Digital Scaling is used to set tag details for a tag that is set to Psuedo Digital Type.

For an 2100-A16, a Psuedo Digital input would be setup as input range RTD 0-850, thus shorted out would give below 0, and open circuit above 850.

Compare Value

This determines the switching value between faulty and healthy indication.

If the value is above the compare value it will be healthy (or Indication Healthy state).
If the value is below the compare value it will be healthy (or Indication Faulty state).

Invert

If Invert is checked, the compare checks above are reversed.

If the value is below the compare value it will be healthy (or Indication Healthy state).
If the value is above the compare value it will be healthy (or Indication Faulty state).

User Defined Indication - Enable

Click enable On to change from healthy and faulty text display to user defined text messages.

User Defined Indication - Healthy, Faulty

This is used to replace the standard "Healthy" and "Faulty" indication with some other text. The Enable check box must be turned on, and the required text typed into the edit boxes. The "Healthy Text" is displayed when the tag's value is non zero, and "Faulty Text" when it is zero. (Note: The alarm state for a digital input can be programmed in the Digital Alarm category).

Units

Enter a text string to appear as the tags units.

Prescaler

A built in math function that can be applied to scale the tags value.
Current Prescaler functions are shown in Prescaler Functions.
