CAN-CBX-AI420 - esd electronics, Inc.

Implemented CANopen Objects
error-code x The 32-bit long error code consists of the CANopen-emergency error code described in
DS 301, Table 21 and the error code defined by esd (manufacturer-specific error field).

manufacturer-specific error field: for CAN-CBX-AI420 always ‘00’, unless
emergency-error-code = 2300 h (see below)
emergency-error-code: The following error-codes are supported:
3110 h - Input voltage to high
- Input voltage of at least one channel 10V
8110 h - CAN overrun error
- Sample rate is set to high, thus the firmware is not able
to transmit all data to the CAN bus.
8120 h - CAN in error passive mode
8130 h - Lifeguard error / heartbeat error
8140 h - Recovered from “Bus Off”
6000 h - Software error:
-EEPROM checksum error (no transmission of this error
message as emergency message)
6110 h - Internal software error
e.g.:
- checksum of saved data is invalid and default values are
loaded
- internal watchdog has triggered
FF10 h - Data lost (A/D-data overflow)
5000 h - Hardware error (e.g. A/D-converter defective)
manufacturer-specific error field: always ‘00’, unless
emergency-error-code = 2300 h (see below)
The data off the emergency frame transmitted by the CAN-CBX-AI420 have the following structure:
Byte: 0 1 2 3 4 5 6 7

An emergency message is transmitted, if an error occurs. If this error occurs again, no further
emergency message is generated. If the last error message disappears, again an emergency message is
transmitted to indicate the error disappearance.
