MAINTENANCE FUNCTION
(1) A displayed message can be cleared by the same procedure as used to turn an LED
OFF. (Refer to Section 9.9.1 (2).)
However, if there are several display causes at a time, the next message is displayed
when the currently displayed message is cleared.
POINT
(1) When LED and LED indicator are left OFF for the error occurrence above, set the
factor number area to 0, which stores the applicable factor numbers from SD207 to
SD209.
Example:
To set the ERROR LED to remain OFF and the LED indicator to remain
blank when a fuse blown error occurs, set "0" in the item number setting
area whose item number is "2".
Since the item number "2" is not set, the ERROR LED and the LED
indicator remains OFF even if a fuse blown error is detected.The ERROR
LED and the LED indicator also remain OFF even if another error whose
error item number is "2" is detected (I/O module verify error, special
module access verify error).
(2) Even if the LED and the LED indicator are set to remain OFF, SM0 (the diagnostics
error flag) is still turned ON, SM1 (the self-diagnostics error flag) is still turned ON,
and the error code is stored in SD0 (CPU diagnosis error register).
