2.7.7 Lock Codes
A Program Lock Code can be entered to prevent unauthorized changing of
parameters. This Lock Code can be entered through the front panel using the
PROGRAM LOCK display. An additional Lock Code can be entered through
remote communications to prevent parameter entry from the front panel while
communicating to Cygnus using remote communications. The word “LOCK” in
inverse video will be displayed in the upper right corner of the display.
HINT: To clear the lock, hold down the clear key on power up. HOWEVER, if no
lock code is present, all parameters will be cleared by doing this.
2.7.8 Datalog
Datalog automatically saves to diskette every time a source shutter closure occurs.
When the Datalog data is saved to a diskette, the information will be saved under
a filename.
Datalog files saved to diskette will be automatically named using the date and
Channel number. The format of the filename is YYMMDDC#.IDL where YY is 00 to
89 for the last two digits of the year 20YY, MM is 01 to 12 for the month, DD is 1 to
31 for the day and # is the Channel number 1 to 6. If the diskette already contains
a file with the same filename as the new datalog information, the new datalog
information will be appended to the old file.
At each source shutter close, the datalog information will be appended to the file
(when saved to diskette) until the end of the Process.
The Datalog data set is defined as follows:
