Hook used to fix the module to the base unit. (Single-motion installation)
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.
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 CPU module.
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):

Off: Normal
Shows serial number printed on the rating plate.
Backup battery for use of the standard RAM and backup power time function.
For connection of battery lead wires.
(Lead wires are disconnected from the connector when shipping to prevent the battery from
