Change a FOUNDATION fieldbus device parameter
You can change device parameters and then send the changes to the device.
When you select a parameter to change, you may be prompted if the device is
commissioned. Some changes are prohibited for commissioned devices. You may also be
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.

2. Go to the parameter you want to change.
See the device documentation for more information. Each device uses different

Note
The Trex unit may disconnect from the device after you make the change. If this
occurs, the change is automatically sent to the device without any additional input
from you.
5. Tap Send.
6. Review the change.
Tap Discard to undo the change and close the screen. Tap Cancel to keep the
change and send it to the device at a later time.
