Tab Information Objects

Open the Information object tab to configure so called Information objects and a Common address (known as ‘data points’ and ‘Global address’ in former Automation_Builder versions). In this tab different information objects and their services for transmission are defined. A data point or information object is identified via a system-wide unambiguous address containing a maximum 5 bytes.

  1. Right-click in the empty view and select Add Information Object with ASDU to add a data group. Select the desired object from the list (e.g. M_SP_NA_1).

    ⇒

    An information object with a corresponding ASDU (Application Service Data Unit) is created.

  2. Configure the settings in the Information Object tab to your convenience.

  3. Double-click a table cell to modify pre-set values. For some ASDUs additional sub information objects can be configured. For this, right-click the already existing ASDU and select Add Information Object to selected ASDU option. This allows configuration of 16 data points at the most (depending on the ASDU type). With Remove Information Object the selected ASDU is deleted.

Description of the columns

  • ASDU name: Knot name of the information object (name of the ASDU).
  • Data type: Data type of the ASDU.
  • ASDU type: Type of ASDU.
  • Common addr: Common address of the ASDU (known as ‘Global Address’ in former AB Versions). Byte 1/2 of the common telecontrol address of the block (range: 0…255).
  • Info obj addr: Together with common address Info obj addr defines the endpoint (range: 0…255).
  • Norm start: Low limit (0 %) of the normalized range for real values and setpoints.
  • Norm end: High limit (100 %) of the normalized range for real values and setpoints.
  • Threshold: Threshold limit beyond which a change of the input value referred to.
  • Description: Table cell for free text. Use this field to describe your configuration settings e.g. differences between configuration variants.
