The following cases of the tool change mode can be differenti-
ated:
Tool change mode off
If a device is separated from the
I-Port connection during opera-
tion, the "Device disconnected"
diagnosis becomes active.
This error is automatically reset
as soon as the connection to the
device is restored.
If a device is connected to an
I-Port connection during opera-
tion, the bus node issues an er-
ror ("Device wrongly connec-
ted").
This error is automatically reset
as soon as the connection to the
device is separated again.
If a device was already found at
the I-Port connection during
switch-on, the "Device discon-
nected" diagnosis is active as
long as the connection to the
device is/becomes separated
during operation.
This error is automatically reset
(diagnosis "Device reconnec-
ted") as soon as the connection
to the device is restored.
Tool change mode on
A fixed address space is re-
served in the image table for
both I-Port devices. As soon as a
device is detected at one of the
I-Port connections, its I/O data
are mapped into the image
table.
Diagnostic messages are not
generated when there is no con-
nection to the device nor in case
of configuration errors (e.g. I/O
length of the device is larger
than I/O length of the tool
change mode).
If a device is connected to an
I-Port connection during opera-
tion, the device is recognised
but no error message is gener-
ated.
