Start-Up and Operation
This chapter guides you through:

powerup and initialization sequences
•
initial link communications
•
normal operation
•
communication exceptions
•
remote expansion chassis power loss
•
invalid RIO link transfers
•
testing the 1747-ASB module
Make sure SW3-8 is ON (save mode) while you setup and debug your
system. When you have completed debugging your system:
System Start-Up 1. Cycle the power one last time in save mode (SW3-8 ON).
2. Remove power from the system.
3. Remove the 1747-ASB module and set SW3-8 to the OFF
position (check mode).
4. Replace the 1747-ASB module in slot 0.
5. Apply power to your system.
Any future changes to the 1747-ASB module's DIP switch or I/O
module configuration results in a 1747-ASB module error, as long as
the 1747-ASB module is in check mode.
The powerup and initialization sequence depends on whether the
1747-ASB module is in the save or check mode (SW3-8). RIO
communications do not commence until a powerup and initialization
sequence is complete.
Powerup and Initialization
Sequences Power must be applied to all of the remote chassis and remote
expansion chassis controlled by the 1747-ASB module before this
sequence can be completed. If the remote expansion chassis are not
powered, a 1747-ASB module error occurs.
