Campbell CR1000 User Manual

Section 8. Operation
• Formatting memory drives.
• Deleting data files associated with the previously running program.
When power is connected to the CR1000, it searches for powerup.ini and
executes the command(s) prior to compiling a program. Powerup.ini performs
three operations:
1. Copies the program file to a memory drive
2. Optionally sets a file run attribute (Run Now, Run on Power Up, or Run
Always) for the program file.
3. Optionally deletes data files stored from the overwritten (just previous)
program.
4. Formats a specified drive.
Execution of powerup.ini takes precedence during CR1000 power-up. Although
powerup.ini sets file attributes for the uploaded programs, its presence on a drive
does not allow those file attributes to control the power-up process. To avoid
confusion, either remove the external drive on which powerup.ini resides or
delete the file after the power-up operation is complete.
8.3.4.4.1 Creating and Editing Powerup.ini
Powerup.ini is created with a text editor on a PC, then saved on a memory drive
of the CR1000. The file is saved to the memory drive, along with the operating
system or user program file, using the datalogger support software
(p. 654) File
Control | Send
(p. 515) command.
Note Some text editors (such as MicroSoft
®
WordPad
®
) will attach header
information to the powerup.ini file causing it to abort. Check the text of a
powerup.ini file in the CR1000 with the CR1000KD Keyboard Display to see
what the CR1000 actually sees.
Comments can be added to the file by preceding them with a single-quote
character ('). All text after the comment mark on the same line is ignored.
Syntax
Syntax for powerup.ini is:
Command,File,Device
where,
• Command is one of the numeric commands in table Powerup.ini Commands
(p. 388).
• File is the accompanying operating system or user program file. File name
can be up to 22 characters long.
• Device is the CR1000 memory drive to which the accompanying operating
system or user program file is copied (usually CPU:). If left blank or with an
invalid option, default device will be CPU:. Use the same drive designation
as the transporting external device if the preference is to not copy the file.
