Chapter 12 Using microSD Cards
Power-up Settings in ConfigMeFirst.txt
On power-up, the controller reads and carries out configuration settings described in the
ConfigMeFirst.txt file. However, the UPD setting also takes effect when the microSD card is
inserted. The configuration settings for the ConfigMeFirst.txt file are shown in the following
table.
ConfigMeFirst.txt Configuration Settings
Setting Takes Effect On... Description
Firmware update settings
[FWFILE] Power-up
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>
[FWDOWN] Power-up
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 revision of firmware file
compared to current firmware in the controller, irrespective
of [FWDOWN] setting.
Controller settings
[PM] Power-up Power up and switch to PROGRAM mode.
[CF] Power-up Power up and attempt to clear fault.
Project settings
[BKD = My Proj1] Power-up
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
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]
Power-up and
Insertion
For normal usage of backup and restore (that is, through
Connected Components Workbench software, Load Always,
or Load on Memory Error settings), set the user project
directory name. For example, My Proj, during power-up or
when the microSD card is inserted.
This directory is also used by data logging and recipe
function.
Network settings
[ESFD] Power-up
Embedded Serial Factory Defaults.
Power up and revert embedded serial comms to factory
defaults.
[IPA = xxx.xxx.xxx.xxx] Power-up
Power up and set IP address to xxx
(must be numbers only).
[SNM = xxx.xxx.xxx.xxx] Power-up
Power up and set subnet mask to xxx
(must be numbers only).
[GWA = xxx.xxx.xxx.xxx] Power-up
Power up and set gateway address to xxx
(must be numbers only).
General settings
[END] Power-up
End of setting.
This setting is always required even when the
ConfigMeFirst.txt file does not contain any other setting.
The SD LED goes off when this setting is not present.
IMPORTANT Flash Upgrade Settings
With Connected Components Workbench software version 12 or later,
you can flash upgrade your Micro800 controller from the microSD card in
addition to using ControlFLASH. See Flash Upgrade From MicroSD Card
on page 269 for instructions.
• [FWFILE] and [FWDOWN] settings must be placed at the beginning of the
file.
