Change a FOUNDATION fieldbus device parameter
You can change device parameters and then send the changes to the device.

prompted that the device will be disconnected from the application after you change the
parameter.
 WARNING
Changing device parameters could adversely affect the control of your process. Put the
control loop in Manual/Out of Service before applying changes. Verify the output before
returning the control loop to Auto. Failure to do so could result in property damage,
serious injury, or death. Ensure all safety precautions and work procedures have been
followed.
