Error class
The error class element provides a more exact classification of the error type. The following error classes are distinguished in accordance with EN 50170.
Class (hex) | Designation | Meaning |
|---|---|---|
1 | vfd state | Status error of the virtual field device |
2 | application reference | Error in application program |
3 | definition | Definition error |
4 | resource | Resource error |
5 | service | Error during execution of service |
6 | access | Access error |
7 | ov | Error in the object list |
8 | other | Other error (see additional code) |
The error class is generated by the communication software of the fieldbus interface if there is an error in communication. This statement does not apply to Error class 8 = Other error. Return codes sent from the frequency inverter system are all included in Error class 8 = other error. The error can be identified more precisely using the additional code element. The Ethernet error code is "0".
