Application Parameters
Device Address (1 to 255) (40400)
Each device within the Modbus network must be assigned a unique address.
Each MPX sensor should be connected to the network individually and assigned
an address. Each sensor is set to address 1 by default.
Units (1 = Feet, 2 = Inches, 3 = Meters) (40401)
Determines the units of measure for the calculated reading (Input registers
30303-30304 and 30305-30306) when in Application Types 0, 1, 7, or 11 (Dis-
tance, Depth of level, Pounds, Curve Fit).
Application Type (1 to 11) (40402)
Determines the type of calculated reading performed by the sensor (refer to
pages 10-18). The calculated readings can be queried from Input registers
30303-30304 (top float) and 30305-30306 (bottom float).
Application Type 0: Distance
Sets the zero reference at the top of the stem and measures downward to
the float position.
Register Function Value Range
40401 Units 1 to 3
40402 Application Type 0
40404 Decimal Place 0 to 3
Application Type 1: Depth of level
Sets the zero reference to the bottom of the stem and measures upward to
the float position.
Register Function Value Range
40401 Units 1 to 3
40402 Application Type 1
40404 Decimal Place 0 to 3
40406 Full Distance Typically = Blanking Distance
40407 Empty Distance 0 to 10364 mm
