This section provides background information for properties. For procedures or workflows, see the step-by-step section.
In Basic mode, some properties may be configured to display only in off-normal state. Advanced mode displays more properties than Basic mode. When you command a property, the status of the command displays for the commanded property.

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:
- When user action is required to manage an emergency
- When an alarm indicates a malfunctioning device
- When performing preventive maintenance
- When energy savings is desired
- When managing operating hours totalization
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
Example of Commanding
At your facility, you want to change the temperature in a conference room from 68 to 73°F (20 to 22.78°C). Using the management station software, you send a command to change the Present Value of the Temperature Setpoint object of the room to override the normal system control.
