Wipe Bubble Procedure
The following procedure describes how to perform a Wipe Bubble
procedure on the ControlFile Nonvolatile Memory. Wiping rewrites the
header and purges the plant configuration information for the specified
Controller Processor card. The command works on Bubble NV Memory
and RAM NV Memory.
CAUTION
When a Wipe Bubble or a Kill Controller procedure is
performed on an MPC I controller, all *ENTRY and *VALUE
items will be lost. Write down the values BEFORE wiping
the configuration.
When a Wipe Bubble or a Kill Controller procedure is
performed on a MUX configuration the calibration constant
of the FEMs will be lost. The calibration constants should
be written on the FEM.
