Section 8. Datalogger Program Creation with Edlog
8.4.1 Program Security
Setting security in the datalogger allows you to restrict access to certain
functions, which helps ensure the program or data are not altered. Security is
unlocked in the datalogger when, upon attempting to connect, PC400 sends the
code entered in the Setup window.
8.4.1.1 Setting Passwords in the DLD
In the Program Security Dialog Box, there is a field for three levels of security.
Enter a non-zero number in the appropriate field to enable security at the
desired security level. This number is used as a password to unlock the
associated security level when needed. If you choose to set level 02, level 01
must also be set. Likewise, if you set level 03, levels 01 and 02 must be set.
CR7 and 21X dataloggers have only 1 level of security. NOTE
8.4.1.2
8.4.3.1
Disabling Passwords
Passwords of 0000 disable the program security. When you disable level 01,
you also disable program security for levels 02 and 03. Similarly, disabling
level 02 disables level 03. All passwords are set to 0000 upon power-up of the
datalogger. When the program is run, security is enabled.
Refer to the datalogger manual or Edlog’s help file for additional information
on Security in the datalogger.
8.4.2 Final Storage Area 2
The ring memory for CR10, CR10X, CR510, and CR23X dataloggers can be
divided into two final storage areas. By default, all memory is allocated to
final storage area 1. However, the datalogger’s memory can be partitioned into
two final storage areas using this option. To allocate memory to Final Storage
Area 2, enter the number of locations into the Final Storage Area 2 Locations
field.
Final storage area 1 is reduced by the amount of memory allocated to final
storage area 2. Data stored in final storage area 2 is protected when Input
and/or Intermediate Storage is reallocated. Data stored in final storage area 1 is
erased when any of the memory areas are reallocated.
8.4.3 DLD File Labels
This option allows you to determine the labels that are saved in the DLD file
for the datalogger. While labels are useful, they can increase the size of the
datalogger program considerably. If program size is a concern, you can limit
or completely eliminate the labels that are saved in the DLD file.
Mixed-array Dataloggers
Mixed-array dataloggers can store the labels for input locations and final
storage output in the DLD file. PC400 uses this information on the Monitor
Data display. If you do not include these labels in the DLD file, you will see
