Status bits Internal inputs that supply coded
common diagnostic messages.
The 8 status bits are transmitted to
the interface as "inputs" cyclically
with the normal inputs.
I/O diagnostics The I/O diagnostics interface is a
interface fieldbus-independent diagnostics
interface at I/O level, which permits
access to internal data of the CPX
terminal (16 inputs and 16 outputs).
