Device diagnostic functions
The following EL4374 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. |
0xF900:11 | Operating Time | operating time of the device in [min], cannot be deleted |
0xF900:12 | Device Temperature | current internal terminal temperature in [°C]. |
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 |
0xF900:15 | Supply Voltage | Informative display of the power contact voltage, measurement uncertainty ±1.2 V in the range 20..29 V. Measurement is not guaranteed for voltages outside this range! |
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) |
0xF915:0C | Error Ch.4 | LED channel 4 (AO) |
