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:

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:
