Function description
The UREGDFB procedure registers the error messages from the diagnostic DFB.
It also makes it possible for the UREGDFB diagnosis DFB to assign an error description to the error types. This makes it possible to distinguish between different error sub-types. The parameter RSEL can be used to define which default message is to be replaced by the user text.
EN and ENO can be configured as additional parameters.

  • 0 = no scheduled status
  • 2 = status is scheduled by a word
  • 4 = status is scheduled by a double word
CTRL
BOOL
  • 1 = User acknowledgement required

UTEXT
STRING
User-defined error description (only active for RSEL = 1-4)
RSEL
INT
Replaced by UTEXT
Possible values:
  • 0: UTEXT is not used.
  • 1: the instance comment is replaced by UTEXT
  • 2: the instance name is replaced by UTEXT
  • 3: the DFB type name is replaced by UTEXT
  • 4: the pin name is replaced by UTEXT

Description of output parameters:
Parameter
Data type
Description
ESTS
ANY
Diagnosis DFB status (declared in parameter OUT to be passed on to address and not value). Before this procedure is called it must be updated by the diagnosis DFB .
ERID
INT
Error recognition used by the function DEREG to de-register active errors.
Note: The connection to other active errors is lost if the same error recognition variable is used for different errors.
STAT
INT
RegistrationStatus
  • If registration is successful: STAT = 0 and ERID is valid
  • If the registration fails: ERID is invalid and
    • STAT = 1: diagnostics buffer is not configured
    • STAT = 2: diagnostics buffer full.
