Indicates the mode of the CPU module.
On: Q mode
Flash:
Executional conditioned device test is being executed.
External input/output forced on/off function is being executed.
CPU module change function with memory card is being executed.
Indicates the operating status of the CPU module.
On: During operation with the RUN/STOP/RESET switch set to "RUN"
Off: During stop with the RUN/STOP/RESET switch set to "STOP"
When an error that stops operation is detected
Flash:
Parameters or programs are written with the RUN/STOP/RESET switch set to "STOP",
and then the RUN/STOP/RESET switch is turned from "STOP" to "RUN."
To turn on the RUN LED after writing the program, perform the following operations.
• Set the RUN/STOP/RESET switch in the order of "RUN"  "STOP"  "RUN".
• Perform reset with the RUN/STOP/RESET switch.
• Power on the programmable controller again.
To turn on the RUN LED after writing the parameters, perform the following operations.
• Perform reset with the RUN/STOP/RESET switch.
• Power on the programmable controller again.
(If the RUN/STOP/RESET switch is set in the order of "RUN"  "STOP"  "RUN" after
changing the parameters, network parameters and intelligent function module
parameters will not be updated.)
On: Detection of self-diagnosis error which will not stop operation, except battery error.
(When operation continued at error detection is set in the parameter setting.)
Off: Normal
Flash:
Detection of the error that stops operation.
When reset operation becomes valid with the RUN/STOP/RESET switch.
On: Annunciator (F) turned on
Off: Normal
On (yellow):Battery error due to battery voltage drop of the memory card.
Flash (yellow):Battery error due to voltage drop of the CPU module battery.
On (green):
Turned on for 5 seconds after restoring of data backed up to the standard ROM by the
latch data backup is completed.
Flash (green):
Flashes when backup of data to the standard ROM by latch data backup is completed.
Off: Normal
On: Start of boot operation
Off: Non-execution of boot operation
