The table below lists the commands supported by the Analog Input Object.

Table 1. Analog Input Commands
Command Name	Parameters	Description
Disable Alarms	None	Disables all types of alarming: alarm extensions, BACnet intrinsic alarming, and BACnet Event Enrollment objects.
Enable Alarms	None	Enables all types of alarming: alarm extensions, BACnet intrinsic alarming, and BACnet Event Enrollment objects.
In Service	None	Cancels the affect of an Out of Service command and returns the Out of Service attribute to False. The Present Value and Reliability will revert back to the values obtained from the physical input. Note: For BACnet objects, this command is dependent on the ability to write the Out Of Service attribute of the BACnet Analog Input object in the remote BACnet device. Objects in the N30, for example, do not support this command.
Out of Service	The value to be written to the Present Value attribute.	Allows a user to override the object’s hardware input for simulation or other purposes. The Out Of Service command will change the Out of Service attribute to True, write the Present Value to the value of the command parameter and write the Reliability attribute to Reliable. The Present Value and Reliability will no longer track the physical input. When an Out Of Service command is issued, the NxE does not communicate subsequent changes (operator or system) to the field device. Notes: For BACnet objects, this command is dependent on the ability to write the Out Of Service attribute of the BACnet Analog Input object in the remote BACnet device. Objects in the N30, for example, do not support this command. For integrated N2 objects, this command is dependent on the ability to set the AI point in the N2 controller to an override state. System 91 controllers, for example, do not support this command.
Temporary Out of Service	The value to be written to the Present Value attribute, along with the hours and minutes that the out of service state is temporarily active.	Allows a user to temporarily override the object’s hardware input for simulation or other purposes for a specified period of time stated in hours and minutes. This command has the same function as an Out of Service command but with the time element.
