The table below lists the commands supported by the Binary Output Object.

Note: For the Release Operator Override, Release, and Release All commands, if all Command Priorities have been released and a Relinquish Default is not defined, the supervisory controller gives control over to the actual hardware.
Table 1. Binary Output Commands

Command Name

Parameters

Description

Disable Alarms

None

Enable Alarms

None

In Service

None

Note: For BACnet objects, support of this command is dependent on the ability to write the Out Of Service attribute.

Operator Override

The value to be written to the Present Value.

  • NOT Local Control and NOT Out Of Service, or
  • NOT Local Control and after issuing the In Service command.

Out of Service

None

For BACnet objects, support of this command is dependent on the ability to write the Out Of Service attribute.

Release Operator Override

None

Release

  1. Attribute name
  2. Command priority

Release All

Attribute name

Important:

The Release All command may not cause an immediate return to automatic operation. The Release All command clears all command priorities, including those that come from applications and features. When this happens, the output point goes to its Relinquish Default condition. In some cases, the application or feature may have sent a command that does not match Relinquish Default. In this instance, the output point does not end in the state that the applications or features intended. This situation can cause unexpected operation to occur; for example, a space might overcool or overheat, a fan might run longer than expected, and so on.

If an operator has overridden an input, use the Release Operator Override command.

State0 ... State1

None

Releases Command Priorities 9 through 15 (Scheduling) and then writes to the Present Value at the Default (16) command priority. If this is the highest, it is sent to the controller. The state command names and number of commands are dependent on the States Text attribute.

Important: Be aware that an operator state command releases the actions of any processes running to the object in the NxE or FEC controllers that use Priorities 9 through 16. Consider this behavior when creating control strategies.

If Local Control is True, this command is rejected.

Temporary Override

The value to be written to the Present Value attribute, in addition to the duration of the override in hours and minutes.

Overrides a point temporarily for a specified period of time. After the specified time period passes, the Override is automatically released.
