Load Memory Always Bit
When this bit is set, you can overwrite a processor program
with a memory module program by cycling processor power. A
programming device is not required. The processor mode after
powerup is as follows for SLC 5/02 and higher processors:
••••
•••
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
status file bit S:1/11 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 nor master password.
When S:1/11 is also set in the status file of the user program
in RAM, the memory module must be installed at all times to
enter the REM Run or REM Test modes.
ATTENTION
The overwriting process, including data tables, is repeated
each time you cycle power.
To program this feature, set this bit using the Data Monitor
function. Then store the program in the memory module.
You may choose not to overwrite data files on a per file basis. • • •
