Quick start proceDure

Additional Hardware and Software Requirements
To operate the DC2227A demo circuit in IO-Link mode,
additional hardware and software are required:
• PC running Windows XP or later with Ethernet Card.
Alternatively a USB-to-Ethernet adaptor can also be used
• LTC IO-Link Master Demo Circuit DC2228A
• DC2228A Control Tool Software
• PoE Injector or 24V Power Supply
• DC2227A IODD Files (COM2 and COM3)
Set-up Preparation (See Figures 1 and 2)
1. Download and install the DC2228A Control Tool soft-
ware from:
www.linear.com/demo/DC2228A
2. Connect the DC2228A to power and the host com-
puter. Refer to the DC2228A demo manual for detailed
information about the different configuration options
to supply the DC2228A and interface it to the PC.
3. Using a 3-wire IO-Link cable of up to 20m in length
with M12 connectors, plug the male terminal to one
of the 8-ports of the DC2228A (for example port 2 like
in Figure 1) and the female terminal to the DC2227A.
4. Run the DC2228A Control Tool on the PC and connect
to the DC2228A. See the DC2228A demo manual for
detailed information of how to select the DC2228A as
the master, configure the IP parameters and establish
communication between the host computer and the
master.
Operation in IO-Link Mode (See Figures 1 and 2)
5. Download the DC2227A IODD files from:
www.linear.com/demo/DC2227A
6. Click on the "Select Device" button and import the
IODD files by selecting the downloaded xml files and
then clicking on the "Import" button (one at a time).

Operation in COM2
7. Click on the "Select Device" button again, this time
making sure the correct port is selected. Use the fol-
lowing IODD file:
TEConcept_GmbH-65538-<YYYYMMDD>-IODD1.1.xml
8. If the device is off, switch it on, enabling the L+ sup-
ply of the connected master's port by pressing the
"Power ON" button keeping the light barrier open
during power-up. If the device was already powered on
coming from COM3 mode, power cycle it keeping the
light barrier open to restart the device in COM2 mode.
See the Light Barrier section for more information.
9. Start IO-Link communication by pressing the "IO-Link"
button. The "Min. Cycle Time" is set to 20ms.
10. If a different IODD file is to be selected, stop IO-Link
communication first by pressing the "Inactive" button
to revert the DC2227A into SIO mode.
Operation in COM3
11. Click on the "Select Device" button again making sure
the correct port is selected. Use the following IODD
file:
TEConcept_GmbH-65539-<YYYYMMDD>-IODD1.1.xml
12. If the device is off, switch it on, enabling the L+ sup-
ply of the connected master's port by pressing the
"Power ON" button keeping the light barrier closed
during power-up. If the device was already powered on
coming from COM2 mode, power cycle it keeping the
light barrier closed to restart the device in COM3 mode.
See the Light Barrier section for more information.
13. Start IO-Link communication by pressing the "IO-Link"
button. The "Min. Cycle time" is set to 800µs.
14. If a different IODD file is to be selected, stop IO-Link
communication first by pressing the "Inactive" button
to revert the DC2227A in SIO mode.
