4-1 Introduction
PC errors can be divided broadly into the following four categories:
1, 2, 3... 1. Program Input Errors
These errors occur when inputting a program or attempting an operation
used to prepare the PC for operation.
2. Programming Errors
These errors will occur when the program is checked using the Program
Check operation.
3. User-defined Errors
There are three instructions that the user can use to define his own errors or
messages. The instructions will be executed when a particular condition
(defined by the user) has occurred during operation.
4. Operating Errors
These errors occur after self-diagnostic program execution has been
started.
a) Non-fatal Operating Errors
PC operation and program execution will continue after one or more of
these errors have occurred.
b) Fatal Operating 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.
The PC’s indicators will indicate when a PC error has occurred and an error mes-
sage or code will be displayed on the Programming Console or host computer if
one is connected. The error code is also contained in SR 25300 to SR 25307.
For the most recent errors, both the type of error and time of occurrence will be
recorded in the PC’s error log area (DM 6570 to DM 6599). Details are provided
in the
CQM1 Programming Manual.
There are flags and other information provided in the SR and AR areas that can
be used in troubleshooting. Details are provided in the
CQM1 Programming
Manual.
Note In addition to the errors described above, communications errors can occur
when the PC is part of a Host Link System. Refer to the
CQM1 Programming
Manual
for details.
Caution Expansion instructions (those assigned to function codes 17, 18, 19, 47, 48, 60
to 69, 87, 88, and 89) are not subject to program checks. Program checks also
do not cover DM 1024 to DM 6143 for PCs that do not support this part of the DM
area (e.g., CQM1-CPU11-E and CQM1-CPU21-E). Data will not be written even
if these areas are specified and data read from these areas will always be
“0000.”
