Note

By Modbus Input Register, the Analog Input is meant. It is possible to only read the Analog Input by getting the state of this input. The register size is 2 bytes.

The Modbus Input Register is configured as follows:

  1. Go to the Modbus Input Register object settings panel which is created on the basis of the Modbus Device object.

  2. In the Address field (1), enter the Input Register address in the register map of this device.

    Note

    Register map is provided by the vendor.

  3. From the Format drop-down list (2), select the register data format:
    • Bin - binary.
    • Dec - decimal.

    • Hex - hexadecimal.

      Note

      The Value area (3) displays the current Input Register value in the selected format.

  4. Click the Read value button (4) if it is necessary to read the device register.
  5. Set the Auto update checkbox (5) if it is necessary to automatically read the register values with the interval specified on the Modbus Device object settings panel.
  6. From the Rule drop-down list (6), select the rule to which this Input Register will obey (see Configuring the Modbus Rule).
  7. Set the Value change checkbox (7) if it is not necessary to display the events on the register value change in the Event Log.  

  8. Uncheck the Indicator change checkbox (8) if it is necessary to allow displaying the register values in the plain text on the map.

    Attention!

    Value change of this parameter will be applied after restarting the ACFA-Intellect Server.

  9. Set the Config event checkbox (9) if it is not necessary to display the events in the Event Protocol when the rule is triggered.
