User parameters
(IP address, device
and module name,
etc.) were lost
when the module
power was cycled,
the front panel
RESET button was
pressed.
Position of Mode switch (7),
Persistent Data Reset, was
changed sometime before
either cycling power or
pressing the RESET button,
causing the user-entered
