    If your monitoring equipment (PLC, etc.) can be configured to interpret the 4-20 mA output(s) of the MPX as volume, then the MPX can be configured accordingly via APG Modbus. See MPX-E/R2 & MPX-E/R3 Modbus Register Lists on pages 19 and 20.

    • MPX-E/R4 Modbus Sensor Parameters 40401 - Units Determines the units of measure for the calculated reading when Application Type is set to 0, 1, or 7. 1 = Feet 2 = Inches 3 = Meters 40402 - Application Type Determines the type of calculated reading performed by the sensor.
  • Page 20 40405 - Maximum Distance (Factory Calibrated) Sets the distance (beginning from the Zero Reference) to the point where the sensor will stop looking for float signals, usually the bottom of the stem. A float beyond the Maximum Distance value will not be detect- 40406 - Full Distance Sets the positive distance (beginning from the sensor Zero Reference) to the point where the monitored vessel is considered full.
  • Page 21 40413 - Filter Window (Factory Calibrated) Determines the physical range (0 - 10,364 mm) of qualified received signals, based on the current raw reading. Signals beyond the +/- Filter Window range of the current reading will not qualify unless the average moves.
  • Page 22 40417 - Offset (Factory Calibrated) Sets the Zero Reference of the sensor, the point from which the calculated distance is measured. 40418 - Pre filter Defines the physical range (0 - 10,364 mm) of the start up (pre-filter) window. Four sample readings must be found within the Pre filter window for the MPX sensor to successfully start up.

    40404 - Decimal Place Determines the number of decimal places included in the Calculated Reading(s). For MPX-E/R2 and MPX-E/ R3, this is seen only when using APG Modbus to program the MPX. This setting does not affect the 4-20 mA output.
  • Page 26 40405 - Maximum Distance (Factory Calibrated) Sets the distance (beginning from the Zero Reference) to the point where the sensor will stop looking for float signals, usually the bottom of the stem. A float beyond the Maximum Distance value will not be detect- 40406 - Full Distance Sets the positive distance (beginning from the sensor Zero Reference) to the point where the monitored vessel is considered full.
  • Page 27 40412 - Averaging (Factory Calibrated) Sets the number of qualified received float signals to average for the raw reading. Qualified received signals are placed in a first-in, first-out buffer, the contents of which are averaged for the raw reading. The larger the number of qualified received signals being averaged, the smoother the reading will be, and the slower the reading will be to react to quickly changing targets.
  • Page 28 40416 - Multiplier (Factory Calibrated) Calibrates the distance reading span. The Multiplier is shown by the values 1 - 1999, but these values are understood to represent 0.001 - 1.999. The default of 1000 (i.e. 1.000) is used for most applications. 40417 - Offset (Factory Calibrated) Sets the Zero Reference of the sensor, the point from which the calculated distance is measured.
  • Page 29 40423 - 1st Float Offset (Factory Calibrated) Used to calibrate top float reading (-10,364 - 10,364 mm). 40424 - 2nd Float Offset (Factory Calibrated) Used to calibrate bottom float reading (-10,364 - 10,364 mm). 40425 - Gain Offset (Factory Calibrated) Used to move the centerline of the float response signal to optimize signal strength (0 - 255).
