4. Apply power from either a 24V power supply or PoE
power sourcing equipment.
5. Start the Control Tool software.
6. Enter the DC2228A communication settings (Figure 8a
and 8b). Using the default address:
IP address = 192.168.10.150
Port = 7
NOTE: The default IP address can be changed using
the procedure given in the section One Time DC2228A
configuration to change the fixed IP address .
7. Connect the Control Tool to the DC2228A using the
green “Connect” button (Figure 8c and 8d).
IO-Link Operation
To operate a connected device that’s been configured for
IO-Link operation (Figure 9):
1. Click the “Power ON” button to supply power to the
device.
2. Click the “IO-Link” button to begin communication.
3. Operate IO-Link device. For a typical sensor this involves
monitoring process data and events.
4. Click the “Inactive” and “Power OFF” buttons when
done.
Digital Input Operation
To operate in DI mode (Figure 10), for receiving data from
a device connected to the C/Q line:
1. If an IODD file has been associated with the port,
remove it using Select device → Exit and not select .
When powered, the connected device will now run in
Standard IO (SIO) mode.
2. Click the “Power ON” button to supply power to the device.
3. Click the “DI” button. The Raw Process Data In field
will monitor the digital state at the C/Q pin.
4. In the case of a DC2227A device, the C/Q state can be
changed by interacting with its light sensor.
5. Click the “Inactive” and “Power OFF” buttons when done.
Digital Output Operation
To operate in DO mode (Figure 11), for switching the C/Q
line as a Standard IO (SIO) output:
1. If an IODD file has been associated with the port,
remove it using Select device → Exit and not select .
When powered, the connected device will now run in
Standard IO (SIO) mode.
2. Consider whether the connected device will tolerate a
C/Q driver conflict. If conflicts occur, master C/Q over-
current events could be triggered (see Fault Conditions
section). If connected to a DC2227A, be aware that the
device output state in SIO mode is determined by its
light sensor. The DC2228A and DC2227A won’t damage
each other. Other devices could be stronger or weaker
than the DC2228A, and might not tolerate a conflict.
3. Click the “Power ON” button to supply power to the device.
4. Click the “DO” button and “OK” the confirmation mes-
sage.
5. Click the “High” or “Low” radio buttons to switch the
C/Q state.
6. Click the “Inactive” and “Power OFF” buttons when
done.
Fault Conditions
If the Control Tool detects a fault on any port, it reports, in
red, a Master PHY event at the bottom of the main window.
The operator may query faults using the Master settings
→ Check PHY events pull-down menu. After fixing the
underlying condition, the operator may clear faults using
the same pull-down menu.
Software License and Renewal
The Control Tool license is valid for 10000 minutes of
cumulative operation. Unlimited free renewals, as well as
an unlimited license, are available. To renew the license:
1. Get the hardware ID using
Tools → License key manager
and clicking the “Export hardware ID” button.
