Table 1 describes the Binary Output object commands. For information about command priorities, see Command Priority Levels.

Table 1. Binary Output Commands

Name

Description

Active Commanding for hardware is on.
Inactive Commanding for hardware is off.

In Service

Cancels the effects of an Out of Service command. This command changes Out of Service to False and reconnects the input to the hardware. If you make changes to Present Value when Out of Service is True, the hardware is commanded when you issue the In Service command.

Operator Override

Replaces Present Value at the Operator Override priority (8) with the value you enter in the command. The override has no effect if a higher priority value is in the Present Value attribute. Min On Time, Min Off Time, Min Cycle Time, or Heavy Equip Delay may apply.

Release Operator Override

Releases an Operator Override command.

Out of Service

Changes Out of Service to True, Present Value to the value you specify, Status to Out of Service, and Reliability to Reliable. Present Value and Reliability are not connected to the hardware when the input is out of service, so this is the only time they are writable. Commands cannot be sent to the hardware output when Out of Service is True.

Re-Command

Reissues the current value of Present Value at the highest active priority to the hardware. This command is used when the hardware is out of sync with Present Value. Present Value is not changed.

The action that results from Recommand is based on system type:
  • Maintained: A command to the expected hardware state is issued to the hardware output.
  • Start Stop: A pulse is issued depending on Present Value and Polarity.
  • Pulse: A pulse is issued.

Recommand is most useful when used in the Pulse mode. Writing Present Value in the other modes (at or above the highest active priority) can be used instead of Recommand in the Maintained or Start Stop modes because redundant commands are sent in those modes. In Pulse mode, no pulse is issued on a write from Active to Active, for example.

If Present value is decoupled from the hardware output, Present Value is Hold, the object is not connected to a hardware object, or field commands have not been enabled, Recommand is ignored.
Note: The return status of the command is OK even if the command is ignored.
Note: Recommand may send an immediate pulse to change the load to the opposite of the current state. No consideration is given to Heavy Equip Delay, Min On Time, Min Off Time, or Min Cycle Time.

Release

Releases a specific priority of Present Value.

Release All

Releases priorities 3 - 15.
