Case
Switching on without a con-
nected I-Port device and sub-
sequent connection.
The I-Port connection is not
configured at the DP master
The I-port connection is deac-
tivated und cannot be used.
2-36
Tool change mode off
If no device is connected to the
relevant 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-Port connection
then is/becomes inactive as well
and can no longer be used.
This error can only be eliminated
by adjusting the configuration or
connecting an I-Port device to
the bus node and restarting the
system.
If a device is recognised at the
I-Port connection when the sys-
tem is switched on, the diagnos-
is "Device wrongly connected" is
reported. The second I-Port con-
nection is then inactive as well
and can no longer be used.
This error can only be eliminated
by adjusting the configuration or
connecting an I-Port device to
the bus node and restarting the
system.
Tool change mode on
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-Port
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 connection to the
device is restored.
If a device is detected at this un-
configured I-Port connection, the
second I-Port connection re-
mains active and effective.
