If an error occurs in the RUN mode, an error display or error code (including a step
number) is stored in the special register by the self-diagnosis function. The error
code reading procedure and the causes of and corrective actions for errors are
shown in Table 11.1.
The followings are the explanation about the descriptions and the causes of the
error messages, error codes and the detailed error codes, and their corrective
actions.
The detailed error codes are stored in D9092 only when using the dedicated
instruction for CC-Link.

Corrective Action
(1) Read the error step by use of
peripheral equipment and correct
the program at that step.
(2) In the case of memory cassette,
rewrite the contents or replace
the cassette with a memory
cassette which stores correct
contents.
