Explanation of Windows Error Codes:

(taken from winerror.h)

Values are 32 bit values layed out as follows -

(Hex) 8 7 6 5 4 3 2 1
(Bin)1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0
±–±±±----------------------±------------------------------+
|Sev|C|R| Facility | Code |
±–±±±----------------------±------------------------------+

Where:

Sev - is the severity code

  00 - Success
  01 - Informational
  10 - Warning
  11 – Error

Eg. 8 = 1000 (Warning)
C = 1100 (Error)
C - is the Customer code flag

R - is a reserved bit

Facility - is the facility code

Code - is the facility’s status code

The facility codes are (in Hex) -

#define FACILITY_WINDOWS 8
#define FACILITY_STORAGE 3
#define FACILITY_RPC 1
#define FACILITY_SSPI 9
#define FACILITY_WIN32 7
#define FACILITY_CONTROL A
#define FACILITY_NULL 0
#define FACILITY_INTERNET C
#define FACILITY_ITF 4
#define FACILITY_DISPATCH 2
#define FACILITY_CERT B

Typical OPC Errors are covered by FACILITY_ITF.
