Diagnostic data
Diagnostics of the SmartWire stations can be performed in a
number of ways:
• As long as the SmartWire modules communicate with the
gateway they send a status bit, which is included in the full
status data. (section "Status bits", page 39)
• The SWIRE-GW-MB monitors the SmartWire stations. It
recognizes the failure of any stations and sets the
corresponding life bit.
• Failed or faulty SmartWire modules are also included in
the parity bits’ register area.

The type and number of supported function codes depend
