Diagnostic code
The diagnostic register of the module includes both the diagnostic selector and the
diagnostic code. This diagnostic code, which is represented in bits 11 to 0 of the register,
is specified in Table 9-3 and onwards. However, it is the code of the entire diagnostic
register that is indicated. To obtain the diagnostic code specified in the documentation,
logically AND the code of the diagnostic register indicated with the code 07FF
hex
.
Example: ANDing the
diagnostic code
Diagnostic code indicated: E281
hex
(Example for an error in VersaSafe mode)
Diagnostic code specified in the documentation: X281
hex
As the first digit is never relevant, the code always starts with an X.
If the same error can occur at different outputs/channels, a generalizing diagnostic code is
indicated with an n where the error location is specified.
Generalizing diagnostic code specified in the documentation: X03n
hex
For some errors a single channel is specified as the error location (e.g., OUT0_Ch1).
Some errors only occur for outputs parameterized for two-channel operation. Here, the
channel pair is specified as the error location (e.g., OUT0_Ch1&2).
