SLC Status File B-11

TIP
All modes in the fixed, SLC 5/01, and SLC 5/02 processors are
considered to be remote because they do not have a
keyswitch.
••••
The memory module you install in the processor must have a
status file bit S:1/12 set. Loading takes place if the master
password and/or password in the processor and memory
module match. Loading can also take place if the processor has
neither a password not master password.
When S:1/12 is set in the status file of the user program in
RAM, it does not require the presence of the memory module
to enter the REM Run or REM Test mode.
Application example: Set both S:1/11 and S:1/12 to
autoload and run every power cycle, and require the presence
of the memory module to enter the REM Run or REM Test
modes.
ATTENTION
If you leave the memory module installed, the overwriting
process, including data tables, is repeated each time you cycle
power. The mode is changed to REM Run each and every
power cycle.
To program this feature, use the Data Monitor function. Then
store the program in the memory module. This feature is
particularly useful when you are troubleshooting hardware
failures with “spares” (replacement modules). Use this feature
to facilitate application logic upgrades in the field without a
programming device.
You may choose not to overwrite data files on a per file basis. • • •
