Device diagnostic functions

The following EL407x device information can be read from the CoE:

Index	Name	Meaning
0xF900:01	Power Good	FALSE: There is approx. < 20.4 V at the power contacts. Operation of the device below this limit is not recommended. Overvoltage is not monitored.
0xF900:11	Operating Time	operating time of the device in [min], cannot be deleted
0xF900:12	Device Temperature	current internal terminal temperature in [°C]. Note: this value depends on the installation position, it is usually well above the ambient temperature.
0xF900:13	Min. Device Temperature	minimum value ever observed by the terminal in [°C], cannot be deleted
0xF900:14	Max. Device Temperature	maximum value ever observed by the terminal in [°C], cannot be deleted

The status of the 5 terminal LEDs can be read electronically as follows:

Index	Name	Meaning
0xF915:01	RUN	RUN-LED
0xF915:09	Error Ch.1	LED channel 1 (AI)
0xF915:0A	Error Ch.2	LED channel 2 (AI)
0xF915:0B	Error Ch.3	LED channel 3 (AO) (if present)
0xF915:0C	Error Ch.4	LED channel 4 (AO) (if present)
0xF915:0D	Error Ch.5	LED channel 5 (AO) (if present)
0xF915:0E	Error Ch.6	LED channel 6 (AO) (if present)
0xF915:0F	Error Ch.7	LED channel 7 (AO) (if present)
0xF915:10	Error Ch.8	LED channel 8 (AO) (if present)

The status of the optical displays (LEDs) in the device can be read out electronically in CoE 0xF915 LED Status, e.g. for simultaneous LED display in the visualization.

These are four bytes that describe the RGB value and the light status:

Byte 1 (from left to right): Flashing/lighting code

0x00: Off/ not available
0x01…0x14: 1..20 Hz
0x80: EtherCAT PreOp
0x81: EtherCAT SafeOp
0x82: EtherCAT Boot
0xFF: On/ available

Byte 2..4:

0x00: Off
0xFF: On

Examples:

0x 00 00 00 00: LED not present
0x FF 00 00 00 : LED is on, RGB =0, i.e. not illuminated, meaning: LED is present
