Note
The LEDs MOT1, MOT2, and IO1 to IO8 are supplied from IO-Link; the LEDs MOT3 and MOT4
are supplied from PWR.
Note
When all LEDs are in the "off" state, a heartbeat (1.9 s off/0.1 s on) is output via all yellow motor
LEDs to signal the general operational readiness of the module. The heartbeat always begins
with a full "off" phase.
Flashing Pattern for Device Identification
In the field, a device can be identified by a flashing pattern. The flashing pattern is activated via
parameter index (127). All LEDs flash in the following pattern:
