Axioline F: diagnostic parameter register

The diagnostic parameter register provides additional information on the error indicated in
the diagnostic status register. The error code is stored in the diagnostic parameter register,
and the error location is stored in the extended diagnostic parameter register. The error lo-
cation is stored as a slot number. This starts at 1 and corresponds to the sequential number
of the Axioline F modules that are installed one after another.
Special case: If an interface error cannot be located, the value 128 is displayed in the di-
agnostic parameter register (bit 7 is set).
The diagnostic parameter register is rewritten whenever a malfunction occurs. If no mal-
function has been detected, the diagnostic parameter register contains the value 0.
