Self-diagnosis Functions

The CPM1 is equipped with a variety of self-diagnosis functions to help identify
and correct errors that might occur and reduce down time.

PC errors are divided into 2 categories based on the severity of the errors. Fatal
errors are more serious errors which stop CPM1 operation. Non-fatal errors are
less serious and don’t stop CPM1 operation.

5-3-1 Non-fatal Errors

PC operation and program execution will continue after one or more of these
errors have occurred. Although PC operation will continue, the cause of the error
should be corrected and the error cleared as soon as possible.

When one of these errors occurs, the POWER and RUN indicators will remain lit
and the ERR/ALM indicator will flash.

Message

FAL No.

Meaning and appropriate response

SYS FAIL FAL**
(** is 01 to 99 or 9B.)

01 to 99

An FAL(06) instruction has been executed in the program. Check the FAL number to
determine conditions that would cause execution, correct the cause, and clear the
error.

9B

An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and
correct as directed.

AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to
DM 6614) when power was turned on. Correct the settings in PROGRAM Mode and
turn on the power again.

AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to
DM 6644) when switching to RUN Mode. Correct the settings in PROGRAM Mode
and switch to RUN Mode again.

AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to
DM 6655) during operation. Correct the settings and clear the error.

SCAN TIME OVER

F8

Watchdog timer has exceeded 100 ms. (SR 25309 will be ON.)

This indicates that the program cycle time is longer than recommended. Reduce cycle
time if possible. (The CPM1 can be set so that this error won’t be detected.)

Communication
Errors (no message)

None

If an error occurs in communications through the peripheral port, the COMM indicator
will be off. Check the connecting cables and restart. Check the error flags in AR 0812
ON.

5-3-2 Fatal Errors

PC operation and program execution will stop and all outputs from the PC will be
turned OFF when any of these errors have occurred. CPM1 operation can’t be
restarted until the PC is turned off and then on again or a Peripheral Device is
used to switch the PC to PROGRAM mode and clear the fatal error.

All CPU Unit indicators will be OFF for the power interruption error. For all other
fatal operating errors, the POWER and ERR/ALM indicators will be lit. The RUN
indicator will be OFF.
