EL8601-8411 - Devices diagnostic functions

The status of the LEDs can be read electronically via CoE object 0xF915:0. The status of the LEDs is displayed as a 32-bit value. The value is interpreted as follows.

Byte 1 indicates the flashing/lighting code with

0x00: LED off
0x01 to 0x82: flashing codes
0xFF: LED on

Byte 4 (R), byte 3 (G) to byte 2 (B) specify the color as an RGB code.

Byte 1 (flashing code)	Byte 2 blue (B)	Byte 3 green (G)	Byte 4 red (R)	Meaning
0x00	00	00	00	LED not present
0x00	FF	00	00	LED is off (blue)
0x00	00	FF	00	LED is off (green) Run LED: EtherCAT State Machine: INIT Signal LED: No signal at the input/output
0x00	00	00	FF	LED is off (red) Error LED: No error at the input/output
0x00	00	FF	FF	LED is off (yellow)
0x00	FF	FF	FF	LED is off (white)
0x01 to 0x14	00	FF	00	LED flashes at 1 Hz to 20 Hz (green)
0x80	00	FF	00	Run LED flashing uniformly (green): EtherCAT State Machine: PREOP
0x81	00	FF	00	Run LED flashing slowly (green): EtherCAT State Machine: SAFEOP
0x82	00	FF	00	Run LED flashing quickly (green): EtherCAT State Machine: BOOT
0xFF	FF	00	00	LED is on (blue)
0xFF	00	FF	00	LED on (green) Run LED: EtherCAT State Machine: OP Signal LED: Signal at the input/output
0xFF	00	00	FF	LED is on (red) Error LED: Error at input/output
0xFF	00	FF	FF	LED is on (yellow)
0xFF	FF	FF	FF	LED is on (white)
