Project restore is done from the subdirectory specified in ConfigMeFirst.txt file
or the Micro820/USERPRJ default folder, if none is specified in the
ConfigMeFirst.txt file. The user needs to ensure that the directory is populated
with correct contents before restoring.
The ConfigMeFirst.txt file is a configuration file stored on the microSD card that
the user can optionally create to customize backup, restore, recipe and data log
directories. The following sections include information on how to configure the
ConfigMeFirst.txt properly.
The Micro800 controller reports a major fault when project backup does

not succeed because the memory card size is exceeded.
Powerup Settings in ConfigMeFirst.txt
On powerup, the Micro820 controller reads and carries out configuration
settings described in the ConfigMeFirst.txt file, as shown in the following table.
ConfigMeFirst.txt Configuration Settings
Setting Description
[FWFILE] File path location of the firmware revision on the microSD card. The
default location is in the following format:
firmware\<catalog number>\<filename of firmware>
[FWBUS] This setting is reserved and may be omitted.
[FWSLOT] This setting is reserved and may be omitted.
[FWDOWN] Sets whether to upgrade or downgrade the controller firmware from the
current revision.
0 = Upgrade firmware; 1 = Downgrade firmware
IMPORTANT: Firmware Upgrade will happen if [FWFILE] setting points to
a newer version of firmware file compared to current firmware in the
controller, irrespective of [FWDOWN] setting.
[PM] Power up and switch to PROGRAM mode.
[CF] Power up and attempt to clear fault.
[BKD = My Proj1] Power up and save the controller project into backup directory,
My Proj1\USERPRJ. Require extra power cycle to clear existing fault first
using [CF] setting or other means.
[RSD = MyProj2] Power up and read the project from restore directory MyProj2\USERPRJ
into controller. Require extra power cycle to clear existing fault first using
[CF] setting or other means. This setting overwrites UPD (or its default)
load always or load on error restore function.
[UPD = My Proj] For normal usage of backup and restore (that is, through Connected
Components Workbench, 2080-REMLCD, Load Always, or Load on
Memory Error settings), set the user project directory name. For example,
My Proj, during powerup or when the microSD card is inserted.
This directory is also used by data logging and recipe function.
[ESFD] Embedded Serial Factory Defaults.
Power up and revert embedded serial comms to factory defaults.
[IPA = xxx.xxx.xxx.xxx] Power up and set IP address to xxx (must be numbers only).
