0001 IO-Link with family
compatible device
4 is operated in IO-Link mode.
The master checks if the Vendor ID and the MSB of the Device ID
(this byte defines the product family) of the connected device
match those of the configured one.
If the master detects a mismatch, the IO-Link communication is
estab
lished, but there is no process data exchange. The device
remains in the safe state (Pre-Operate). Parameters and diagnos-
tic information can be read and respectively written.
0010 IO-Link with compati-
ble device
4 is operated in IO-Link mode.
The master checks if the Vendor ID and the Device ID of the con-
nected device match those of the configured one.
If the Vendor ID matches, but the Device ID not, then the master
tries t
o write the Device ID to the device.
If the writing is successful, then the device is a compatible one,
process data exchange is possible.
If writing the Device ID is not su
ccessful, then process data
exchange is not possible. The device remains in the safe state (Pre-
Operate). Parameters and diagnostic information can be read and
respectively written.
0011 IO-Link with
identical device
4 is operated in IO-Link mode.
The master checks if the device type (Vendor ID
and Device ID)
and the serial number of the connected device match the data of
the configured one.
If the master detects a mismatch, the IO-Link communication is
estab
lished, but there is no process data exchange. The device
remains in the safe state (Pre-Operate). Parameters and diagnos-
tic information can be read and respectively written.
0100 DI (with parameter
access
)
Pin 4 is generally operated as simple digital input.
However, an acyclic parameter access from the PLC or the DTM is
possible.
The IO-Link master starts the port in IO-link mode, parameterizes
the d
evice and sets the port back into DI-mode. The port remains
in DI mode until a new IO-Link request is sent from the higher-
level control.
Data storage is
not supported!
Connected devices have to support the SIO-mode (DI-mode).
DI: Pin 4 is operated as simple digital input.
Data storage is
not supported!
NOTE
Parameter Mode", "DI (with parameter access)":
In case of a parameter access, the IO-Link communication at the port is started.
Switching signals are interrupted!
