Parameter data
format When parameters are set via the fieldbus interface, the same parameter coding is used
as with the serial RS485 interface or the system bus.
5.4 Return codes for parameter setting
Elements If parameters are set incorrectly, the MOVI-PLC
®
basic DHP11B.. controller returns
various return codes to the parameter setting master, providing detailed information
about the cause of the error. Generally, these return codes are structured. SEW distin-
guishes between the elements:
• Error class
• Error code
• Additional code
These return codes are described in detail in the Fieldbus Communications Profile
manual and are not included in this documentation. However, the following special
cases can occur in connection with PROFIBUS:
Error class The error class element provides a more exact classification of the error type. The
MOVI-PLC
®
basic DHP11B.. controller supports the following error classes defined in
accordance with EN 50170(V2):
Error code The error code element allows for a more detailed identification of the error cause within
the error class and is generated by the communications software of the fieldbus card in
case of a faulty communication. For error class 8 = other error , only error code = 0 (other
error code) is defined. In this case, detailed identification is made using the additional
code .
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 Fault during execution of service
6 access Access error
7 ov Error in the object directory
8 other Other error (
