Expect device
This I-port configuration alway s requires a device to be con-
nected to the corresponding I-port. An I-port with this config-
uratio n must always be connected to a device. Otherwise an
error will be output.
Auto mode
Tool change mode
If no device was present at the respective I-port
at startup, no I/O data will have been mapped to
the image table. “Device configuration failed”
will be output. All other I-ports are then likewise
inactive and c an no longer be used.
This error can only be reset by eliminating the
cause of the error and subsequently restarting
the system.
If a device was detected at the I-por t at startup,
the “device disconnected” diagnosis will be ac-
tivated if the device is disconnected during oper-
ation.
This error is a utomatica lly reset (diagnosis:
“devic e reconnected”) as soon as the connec tion
to the device is reestablished.
A fixed address space is reserved in the image
table for each I-port. As soon as a device is de-
tected at an I-port, its I/O data are mapped to
the image table.
The “device disconnected” diagnosis will be ac-
tivated if t he device is disconnected during oper-
ation.
This error is automatically reset as soon as the
connection to the device is reestablished.
If a device with an I/O length greater than that
configured in tool change mode is connected, an
“output data size is greater than co nfigured” er-
ror is signalled at the relevant port until the
device is disconnected from t hat port.
All other I-ports will remain active and usable.
