Only those Metasys system commands that can be implemented by a standard BACnet service are supported on an integrated BACnet object. Some BACnet objects support commands that are handled by writing to the remote BACnet object’s properties.

The following table lists the commands that are available for each of the BACnet object types that are supported in the supervisory controller for BACnet/Field Bus integration.

Operation for most of these commands can be found in Metasys SMP Help (LIT-1201793). The following command operations are unique to the BACnet integration:

  • Restore Controller States Text: For objects supporting the States Text attribute, if the User Selected States Text attribute is true, the object's States Text is no longer synchronized with the States Text, Action Text, Active/Inactive, or Shed Level Description property. Use the Restore Controller States Text to set User Selected States Text to false. The field point's States Text attribute is then updated to match the remote object's States Text property.

    Note: If the dictionary cannot be updated to match the field device, the States Text Error Status attribute indicates the cause of the error.

  • State N: The State N Command is used by the Command object to write the Present Value attribute by selecting a state. The first state in the drop-down box indicates No Action, and the remainder of the states indicate an Action from the Action array. If you choose to define your own custom enumeration set for this object, be sure to enter No Action for the first entry.

  • Add Recipient and Remove Recipient for the Notification Object: Use this command to add or remove the parent supervisory device as a notification recipient for the selected Notification object.

  • Adjust: For the Loop object, the Adjust command writes the Setpoint attribute.

  • Out of Service and Temporary Out of Service: If you want to write and make reliable Present Value, first select an out of service or temporary out of service command to the input object, then set the Value before issuing the command. Objects that include this functionality include Accumulator, AI, BI, MSI, Pulse Converter, and Schedule mappers.
