PROGRAM or RUN mode (or on powerup) and the ConfigMeFirst.txt file is
either unreadable or invalid. The ConfigMeFirst.txt file will be invalid when it
has the following errors:
• unrecognized setting (that is, the first three configuration rules have not
been followed),
• the setting parameters after the = symbol is invalid, does not exist, or out of
range,
• the same setting exists twice or more,
• one or more non-setting characters exist within the same bracket,

IMPORTANT Powerup Network Parameter Settings
• [IPA], [SNM] and [GWA] follow the general IP configuration rules.
• [IPA], when set in ConfigMeFirst.txt, should always be configured
with a valid [SNM] and vice versa.
• When optional [GWA] setting is used, make sure that [IPA] and [SNM]
settings are also present in ConfigMeFirst.txt.
• The [ESFD], [IPA], [SNM], and [GWA] settings overwrite the respective
communication settings from project restore due to [RSD], Load
