Using microSD Cards Chapter 10
ConfigMeFirst.txt Errors
The SD status LED goes off when the microSD card is inserted during
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,
• 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
• [END] setting does not exist (even if there are no other settings in the
configuration file).
The microSD card becomes unusable until the ConfigMeFirst.txt file becomes
readable or the errors are corrected.
Deliver Project Updates to Customers Through Email
A benefit of using the project backup and restore feature is to allow you to deliver
project updates to customers through email. You can do so by following the
example shown below.
Backup project to microSD card
The first step is to back up the project from the controller into the microSD card.
1. In Connected Components Workbench, verify that you have downloaded
the updated project to your controller.
2. Insert a microSD card into the microSD card slot.
3. Set the controller to program mode.
4. Under the Memory Card option in your controller settings, click Backup
to Memory Card.
The Backup to Memory Card button is enabled when the
controller is in program mode and a microSD card is in the
microSD card slot.
