6-2 Start-Up and Operation
Save Mode
When power is applied in save mode, the 1747-ASB module:
1. Performs power up diagnostics
2. Reads and verifies the actual DIP switch and I/O module
configuration
3. Saves the DIP switch and I/O module configuration
4. Waits for RIO link communications from the scanner
Check Mode
When power is applied in check mode, the 1747-ASB module:
1. Performs power up diagnostics
2. Verifies the stored configuration integrity
3. Compares the actual DIP switch, I/O module and chassis
configurations to the stored configurations
4. Waits for RIO link communications from the scanner
1747-ASB module errors found during powerup and initialization are
noted in chapter 7.
After successfully completing a powerup and initialization sequence,
the 1747-ASB module waits to receive RIO link communications from
the scanner for all of its logical devices. Once the 1747-ASB module
receives RIO link communication for all of its logical devices, it begins
normal operation.
