This parameter determines how the state of the external switch is mapped to the internal
states of the DIO module:
State of the external switch Internal state of the DIO module
Contact type = Normally open Contact type = Normally closed
Open Inactive Active
Closed Active Inactive
Behavior in special situaions:
During start-up Unknown Unknown
Fault in measurement Error Error
• The internal state of the Digital Input can be transferred to a Digital Output or can
be used to control the measurement.
• The Digital Xx-x submenu contains additional parameters for a more detailed
configuration of the Digital Input. For a description refer to →  148.
9.4.6 Linking input values to tank variables
Measured values must be linked to tank variables before they can be used in the Tank
Gauging application. This is done by defining the source of each tank variable in the
following parameters:
Tank variable Parameter defining the source of this variable
Bottom water level Setup → Advanced setup → Application → Tank configuration → Level
→ Water level source
Average or spot temperature of the
product • Setup → Liquid temp source
• Setup → Advanced setup → Application → Tank configuration
→ Temperature → Liquid temp source
Temperature of the air surrounding
the tank Setup → Advanced setup → Application → Tank configuration
→ Temperature → Air temperature source
Temperature of the vapor above the
product Setup → Advanced setup → Tank configuration → Temperature → Vapor
temp source
Density of the product Setup → Advanced setup → Application → Tank configuration → Density
→ Observed density source
Bottom pressure (P1) Setup → Advanced setup → Application → Tank configuration
→ Pressure → P1 (bottom) source
Top pressure (P3) Setup → Advanced setup → Application → Tank configuration
→ Pressure → P3 (top) source
Depending on the application not all these parameters will be relevant in a given
situation.
The product level is always the level measured by the Micropilot itself. It needs not to
be linked.
