Board error
For Serial Communications Boards, refer to the following error flags. When an
error occurs, the corresponding flag is turned ON. All of these flags represent
non-fatal errors.
Name
The Board has failed.
There is a problem with the com-
munications port.
A checksum error was found in the
protocol data.
An error occurred when the PMCR
instruction was executed.

Turns ON when an error occurs in
the slot 1 Inner Board. The error
code for slot 1 is stored in
AR 0400 to AR 0407.
The Board has failed (watchdog
timer error). IR 20000 will also be
ON.

Refer to the errors in IR 200.
When a fatal error occurs, the ERR/ALM indicator on the CPU Unit will light.
When a non-fatal error occurs, the ERR/ALM indicator on the CPU Unit will
flash. Refer to the indicator error displays.
Note The ERR/ALM indicator will continue to flash even after the cause of a non-
fatal error has been removed for the Serial Communications Board. The indi-
cator can be stopped by clearing the error from a Programming Console or
other Programming Device. Press the FUN Key and then the MONITOR Key
from the Programming Console. Refer to the CX-Programmer Operation Man-
ual for the CX-Programmer procedure.
