Diagnostics
The system SmartWire Darwin provides you with cyclic and
acyclic diagnostic information.
Cyclic diagnostics information
This basic diagnostic information is coded in the normal I/O
map of each SmartWire-Darwin slave. They provide
information about whether the slave participates in the
normal data interchange, i.e. the slave is on the network and
exchanging data via the SmartWire-Darwin network.
Furthermore, it is reported whether any current diagnostic
messages are pending. These two information items are
located in the first input byte in bit positions 4 and 6 for all
SmartWire-Darwin slaves. They permit fast and easy
assessment of the condition of the SmartWire-Darwin slave.
• The slave is available and integrated actively into the
network.
• The slave is operating fault-free.

one byte input (switch position indicator and diagnostic
information)

h Please refer to the documentation of the PROFIBUS-DP
master XIOC-NET-DP-M in the manual AWB2725-1452
for basic information on the DP diagnostics.
You will find explanations there on access to the
diagnostic data of a DP slave station.
