Description
Displays the operating status.
On: Operating
Off: When 5V power supply was disconnected or a watchdog timer error occurred
This part is combined with an I/O status indicator LED to display the error occurrence status at each I/O
*1
terminal.
On: An error occurred (minor error).
Flashing: An error occurred (moderate error).
Off: Normal operation
Depending on "LED display settings during an error", displays the wait-for-restart state after the safety
module is enabled or the error occurrence state.
• When "Do not display I/O error" is set
Flashing (400ms cycle): Wait-for-restart
Off: Normal operation
• When "Always display I/O error" or "Display I/O status and error switching (1 second interval)" is set
A minor error occurrence can be checked.

Displays the module operating status (related to SIL2 mode).
On: Safety I/O in operation
Flashing (1s cycle): Safety I/O stopped
Flashing (400ms cycle): Executing the module position check
Off: Operating in normal mode
Depending on "LED display settings during an error", displays the I/O status or error occurrence status of
each I/O terminal.
• When "Do not display I/O error" is set
On: I/O signal turned on
Off: I/O signal turned off
• When "Always display I/O error" or "Display I/O status and error switching (1 second interval)" is set
The I/O where a minor error occurred can be identified.
