8.3 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 in the extended diagnostic parameter register. The error location 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.
The diagnostic parameter register is rewritten whenever a malfunction occurs. If a malfunc-
tion has not been detected, the diagnostic parameter register contains the value 0.
Exception: If an interface error cannot be located, the value 128 is displayed in the diag-
nostic parameter register (bit 7 is set).
