Define the Main Settings of the SNMP Object Models

Repeat this procedure for each DPT object model that was added to the Object Model folder of the SNMP library.

  1. In System Browser select Project > System Settings > Libraries > [L4-Project] or [L3-Country] or [L2-Region] > Global > SNMP > Object Model > [SNMP object model].
  1. Select the Models & Functions tab.
  1. Open the Main expander. Here you must define the basic settings of the SNMP Object Model.
  1. Select the Default property.
    This parameter is the property that appears in the Value column of the Textual Viewer (System Manager in Operating mode).
  1. Select the Managed type.
    This parameter indicates the application that is loaded when selecting the data point instance.
    NOTE: Always use SNMP Object for the SNMP points.
  1. Leave Generic create and Generic delete unselected.
    These options enable the possibility to add or delete the point instance (point added in the configuration under the SNMP network) from the Object Configurator tab.
    NOTE: Do not use these options for the SNMP devices. Setting these options may result in an unwanted behavior when deleting these objects.
  1. (Optional) Select the Limit number of children option.
    This option limits the number of objects that can be added under the data point instance to the value set as Max. children.
  1. (Optional) Enter the Default name.
    If configured, it indicates the name and description used in the New Object dialog box when adding an SNMP device under the SNMP network.
  1. Specify Parents: GMS_SNMPNetwork.
    This setting indicates the parent DPT of the SNMP device. If configured, the SNMP device can be added to the project under the configured parent node only. In the above example, MySNMP_Device can be added only under the SNMP network.
    NOTE: When configuring SNMP, always set GMS_SNMPNetwork as parent. This allows adding the SNMP device under the SNMP network. If you do not configure the parent properly, it will not be possible to add the SNMP device to the project configuration.
  1. In the Presets section, specify Discipline, Subdiscipline, Type, and Subtype values for the SNMP DPT.
    These settings can be used, for example, in scopes or operating procedure configurations.
