LED
The "LED" column specifies which local diagnostic LEDs indicate the error.
Acknowledgment
To remove the error, evaluate the PUR and OAR bits in the diagnostic register of the
IC220SDL953 (see "Dev-Ack-x (device acknowledgment)" on page A-17). These specify
whether a power up is expected or whether an acknowledgment is required.
Errors that must be acknowledged are indicated with "Yes" in the "Acknowledgment"
column. Special conditions for re-enabling an output or the module are specified in
brackets [e.g., Yes (1)] in the "Acknowledgment" column and explained below the relevant
table.
