controller.
n On-process: The primary CPM is synced with the secondary CPM.
ATTENTION: On-process is ONLY applicable for upgrading
R150 to later release firmwares.
n Off-process: The primary CPM is not synced with the secondary
CPM.
For ControlEdge 900 Controller, it is ONLY allowed in Stopped,
Running or Stop Locked operating mode.
You can rotate the mode switch on CPM to change the operating
mode, see "CPM mode switch" in ControlEdge 900 Platform

the REMOTE position, See "Setting operating modes" on page1
