6.4 STATUS BITS
The valve terminal/valve sensor terminal makes
available 2 status bits for diagnosis, irrespective
of the protocol set.
PLEASE NOTE
The two status bits are only available on the
valve sensor terminal.
The status bits are configured like inputs and al-
ways occupy the four highest-value addresses of
the available address range.
The diagnostics information of the four status
bits is coded and contains the following
meaning:
Diagnostic
information Meaning Cause
