Diagnostic functions
PROFIBUS DP provides an extensive set of diagnostic functions for quick
error localization. Diagnostic messages are transferred via the bus and
collected by the master.
In the case of a diagnostic with DP-V1 the DP slave gets a feedback from
the DP master. With DP-V1 the device related diagnostic has been
improved as further function and is subdivided into the categories
interrupts
and
status messages
.
The diagnostic messages, which were created by the PROFIBUS slave,
have depending on the parameterization, a maximum length of 127byte.
The structure of the diagnostics data may be influenced by the properties
dialog of the IM 306 DP slave. Here the
Identifier/Channel related
diagnostic
and the
Module status
may be activated respect. deactivated.
Byte 0 ... 5 Standard diagnostic data
Byte x ... x+3 Identifier related diagnostic
Byte x ... x+8 Module status
Byte max. 40
⋅
(x ... x+2) Channel related diagnostic
Byte x ... x+11 Interrupt
may be enabled or disabled
via parameterization
