Grouping and overview of the diagnostics messages
The diagnostics messages are grouped according to their cause.
This grouping is visible in the corresponding overview:
–
Grouped overview:
Main group | Sub-group | Error number
e.g. 02 | 01 | 0022
–
Ungrouped overview:
diagnostics number
e.g. 33619990
The diagnostics messages are mapped within the Interfaces corresponding profiles of the Host-Sys-
teme and device profiles in use. If the Host-System or device profile only allows 16 bits, only the
unique error number is transferred.
The diagnostics number of the ungrouped overview is determined from the grouped overview as
follows:
1. Combine main group, sub-group and error number byte by byte as a hexadecimal 4-byte value:
–
Main group = byte 4
–
Sub-group = byte 3
–
Error number = byte 2 and 1
2. The resultant hexadecimal 4-byte number displayed as a decimal number equals the diagnostics
number in the ungrouped overview.
The diagnostics categories listed are used in several product areas, including outside CPX-AP.
Depending on the specific product used, only parts of this complete list will be used.
