Switching on without a con-
necte d I-Port device and sub-
sequent connection.
If no device is connected to the
relev ant I-Port connection at
switch-on, no I/O data are
mapped into the image table. As
a result, the “Device configura-
tion failed” diagnosis is output.
The second I-Por t connection
then is/becomes inactive as well
and c an no longer be used.
This error c an only be eliminated
by adjusting the configuration or
connecting an I-Port device to
the bus node and restarting the
system.
A fixed address space is re-
served in the image table for
each I-Port device. As soon as a
device is detected at an I-Por t
connection, its I/O data are
mapped into the image table.
The “Device disconnected” dia-
gnosis is active as long as the
connection to the device is sep-
arated during operation. This er-
ror is automatically reset as
soon as the c onnection to the
device is restored.
