In Service |
None |
This command cancels the effect of an Out of Service (Command) 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, support of this command
is dependent on the ability to write the Out Of
Service attribute.

|
Out of Service (Command) |
The value to be written to the Present Value attribute. |
This command allows a user to override the object's hardware input. The Out Of Service command changes the Out of Service attribute to True, writes the Present Value to the value of the command parameter and writes 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. For BACnet objects, support of this command is dependent on the ability to write the Out Of Service attribute. |
|
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. |
