  • Page 20: Chapter 3: Programming

    An APG RST-6001 Modbus Controller can be used in tandem with APG Modbus software to program and control up to 20 MPXI-F8 series sensors. Through APG Modbus, you can monitor the raw readings from the sensor, configure the data for distance, level, volume, or weight, and enter measurements for a strapping chart.

  • Page 21: Ma Programming With Rst-4100 And Apg Modbus Software

    An APG RST-4100 Programming Module can be used in tandem with APG Modbus software to program a single MPXI-F6/7 series sensor. Through APG Modbus, you can configure the 4 mA and 20 mA output setpoints and calibration settings. If your monitoring equipment (PLC, etc.) can be configured to interpret the 4-20 mA output(s) of the MPXI-F as volume, then the MPXI-F can be configured accordingly via APG Modbus.

    • MPXI-F8 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 24 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 25 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 26 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 MPXI-F sensor to successfully start up.
  • Page 27 40446 - Baud Rate Selects the communication speed between the sensor and the Server Device. All devices on the network must use the same Baud Rate. APG Modbus Server and Client devices default to 9600 Baud. 0 = 9600 1 = 19200...

  • Page 31 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 32 40412 - Averaging 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 33 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 34 40424 - 2nd Float Offset Used to calibrate bottom float reading (-10,364 - 10,364 mm). Differences in fluid specific gravity can change the level at which a float rests in the liquid. Use this parameter to match probe reading to confirmed liquid level.
