I/O-Module Diagnostics
Digital Input Modules
The digital input modules BL20-4DI-NAMUR with diagnosis function
have supplementary diagnostics which can not be sent via detailed
error codes.
In case of an error occurring at one of these modules, the gateway
sends an error frame specifying the module- and channel-number of
the respective module as well as a common error classification.
If necessary, detailed information about the diagnostic message,
can be read from a manufacturer specific object, the "object 3042
hex
XBI Diag Word" (see next page).
Note
For the exact byte assignment of the Emergency frame, please see
"Structure of the Emergency Frames", page 5-3.
Note
Objects 3000
hex
to 3097
hex
enable direct access to the internal mod-
ule bus of the BL20 station.
