The program includes the configuration table, I/O map, configuration extensions,
segment scheduler, all .EXE loadables and the entire state RAM, including user
logic.
Change program means: a complete program change.
Update program means: to update the user logic
If you reprogram your Primary controller or replace the Standby controller, you may
use the update feature to copy the full program of the Primary controller to the
Standby. This feature not only saves time, but also ensures that the controllers have
identical user logic.
If program changes include any of the above, or replacing the Standby controller,
the Standby must be in dim awareness before a keyswitch update can be performed
Note: Program downloads:
Note: A program update can only be performed from the Primary controller to the
Standby. The Standby controller cannot update the Primary.
Note: To put the Standby into dim awareness, remove the battery for at least 5
minutes.
CAUTION
Battery Hazard
Whenever installing a new controller, be sure its battery has been
disconnected for at least five minutes.
Failure to follow this precaution can result in injury or equipment
damage.
