Diagnostic byte for Suconet K stations
The diagnostic bytes for each station and any local
expansion modules connected to them can be
scanned to obtain more detail about the information
contained in the diagnostic status word. Only read
access is possible.
Every station and local expansion module on the
Suconet K line has its own status information. The
available information will depend on the type of

The status information indicates, for example,
whether
The device ID is incorrect

Suconet bus or is not responding
A short-circuit has occurred at a station’s digital
output, etc.
