2.5.2 Operation/Extended Operation Reference
This section provides background information for using the Operation and
Extended Operation tabs. For related procedures, see Working with
Operation/Extended Operation [➙ 60].
2.5.2.1 Overview of Operation/Extended Operation
The Operation and Extended Operation tabs allow you to display and change the
current state of an object’s properties in your building control system. The
Operation tab is designed for the most common daily tasks, and the Extended
Operation tab is designed for more detailed tasks. Access to objects is based upon
the object privileges and privilege profiles set for you by your system administrator.
Properties and Commanding
You change the current state of a property by commanding it. Once you command
a property, the status of the command displays for the selected object. If the
command fails, the reason for the failure displays so that you can take further
action.
Examples of common commands:
● Acknowledge
● Change command priority
● Coldstart
● Enable/disable
● On/Off
● In service/Out of service
● Override/Release
● Reset value for equipment operating hours
● Set a new point value
● Upload
Display of Properties
Properties display in one of two ways—automatically or manually. They display
automatically when a property goes into an off-normal state, and they display
manually when you select an objects in the system.
Why Command a Property?
You command a property to change its current state. For example, you might
command to initiate an action, enable or disable a property, acknowledge or reset
the status of a property, or override or release an override of a control program.
Commanding a property is also useful under these conditions:
● User action is required to manage an emergency
● When an alarm indicates a malfunctioning device
● When performing preventive maintenance
● To save energy
● When managing operating hours totalization
Example of Commanding
At your facility, you want to change the temperature from 68 to 73°F (20 to
22.78°C) in a conference room on your floor. Using your building control software,
you send a command to change the Present Value of the Temperature Setpoint
object of the room to override the normal system control.
