Chapter 11 Using microSD Cards
Sample ConfigMeFirst.txt File
General Configuration Rules in ConfigMeFirst.txt
• All settings must be in upper case and enclosed in brackets [ ].
• Each line must contain only one setting.
• Settings must always appear first in a line.
• Comments are started with the # symbol.
• No action related to the setting will be carried out when the setting does
not exist, or a # symbol appears before the setting (example, #[PM]).
ConfigMeFirst.txt Errors
The SD status LED goes off when the microSD card is inserted during
PROGRAM or RUN mode (or on power-up) 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,
• space in between setting characters (example, [P M]), or
• space in between IP address, subnet mask, and gateway address (for
example, xxx. x xx.xxx.xxx)
• only one of the network parameter settings ([IPA], [SNM], or [GWA]) is
assigned
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 Always
or Load on Memory Error.
