IO structure Diagnosis
The Web-IO sends the Diagnosis structure in reply to the
ReadDiagnosis structure.
Diagnosis WORD send_sequence always 0
(Web-IO -> PC) WORD rec_sequence always 0
WORD struct_type 0x00D0
WORD length 0x001C
LONG word_anz in this version 4
LONG diag_error_count quantity of pending errors
LONG diag_errorbits0 binary error encoding
LONG diag_errorbits1
LONG diag_errorbits2
The variable diag_error_count returns how many different
errors are currently in the error log. The Web-IO differentiates a
variety of different error states, whereby each set bit in the vari-
ables diag_errorbits0, diag_errorbits1 and diag_errorbits2
stands for an error type.
The exact text description can be opened using TCP Port 80.
