10.1.2 Error types
Errors are divided into the following two types.
(1) Module stop error
(a) The ERR. LED flashes.
(b) When a module stop error occurs, the MES interface function of the MES
interface module is stopped.
Correct the error according to the error code, and turn the power OFF and then
ON or reset the programmable controller CPU.
(c) An error code is stored in the buffer memory area that is corresponding to the
error location.
For how to find an error code, refer to the following:
Section 10.1.1 Finding an error code
(2) Module continuation error
(a) The ERR. LED turns on.
(b) When a module continuation error occurs, the MES interface module continues
operation of the MES interface function.
By correcting the error according to the error code, the correction can be reflected
in the operation.
Since the ERR. LED stays ON, turn it off by the following:
• Error clear request (Y10)
• [Online] - [Remote operation] - [Clear error]
Section 7.13.2 (4) Clear error
