5. Verify the FloBoss performs as required.

6. If you changed the configuration, save the current configuration data to permanent configuration

memory.

7. If you changed the configuration or any FSTs, save them to disk. See Section 2.5.2 for more

information on performing these saves.

2.5.4 Warm Start

A warm start temporarily suspends all input/output (I/O) scanning. I/O processes are restarted from

their last calculated values. A warm start clears and restarts all user-enabled flags. A warm start also

starts all FSTs to the first instruction.

If your FloBoss is semi-functional, perform the RAM Backup Procedure

before removing power from your FloBoss. Refer to Section 2.5.2, Backup

Procedure Before Removing Power, on page 2-21.

To perform a warm start, remove power from your FloBoss and reapply power.

A cold start reloads all configuration data from electrically erasable read only memory (EEPROM),

clears all history, events, and alarm logs, disables all user program tasks, and disables all user data

types. The RESET switch permits a restart from the boot block of the flash memory (cold hard start)

rather than from RAM (warm start). Hold the RESET switch down during power-up to initiate a cold

hard start; otherwise, the switch has no effect.

If your FloBoss is semi-functional, perform the previously described RAM

Backup Procedure before removing power from your FloBoss. Refer to

Section 2.5.2, Backup Procedure Before Removing Power on page 2-21.
