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.
IMPORTANT
The Micro800 controller reports a major fault when project backup does
not succeed because the memory card size is exceeded.
ConfigMeFirst.txt Configuration Settings
Setting Description
[PM] Power up and switch to PROGRAM mode.
[CF] Power up and attempt to clear fault.
[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).
[SNM = xxx.xxx.xxx.xxx] Power up and set subnet mask to xxx (must be numbers only).
[GWA = xxx.xxx.xxx.xxx] Power up and set gateway address to xxx (must be numbers only).
[BKD = My Proj 1]
Power up and save the controller project into backup directory,
My Proj 1\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.
[END] 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 Directory Settings
• If no directory has been specified in the ConfigMeFirst.txt file, then
backup and restore will occur in the controller name directory
(Micro820/USERPRJ, by default).
• If [UPD] is configured in the ConfigMeFirst.txt file, then backup and
restore will occur in the [UPD] directory specified.
• [BKD] setting is implemented even when the controller is locked or
password protected.
• [BKD] directory is automatically created if it does not yet exist.
