DEMO MANUAL DC2228A
Quick start proceDure
The following hardware and software are required:
• PC running WinXP or later with Ethernet or USB-to-
Ethernet adapter
• TEConcept Control Tool software. See Step 1.
•
24V power supply or PoE power sourcing equipment
(PoE injector or PoE switch).
• One or more IO-Link devices, such as Linear
Technology’s DC2227A.
This procedure assumes a 24V power supply and a dynamic
IP address assigned via DHCP. Operation using PoE or a
fixed IP address is described elsewhere in this manual.
1. Download and install the DC2228A Control Tool software
from: www.linear.com/demo/DC2228A .
2. Hook-up (Figure 1):
a. Set the power source selector (S1) to the EXT position.
b. Keeping its output disabled, connect a 24V input
power supply to J5.
NOTE: Ensure that the input voltage does not exceed 30V.
c. Connect an Ethernet cable between J1 and the network
to which the PC is connected.
d. Connect one or more IO-Link devices using the M12
connectors (J21–J28) and cables up to 20m in length.
Refer to Table 1.
3. Turn on the 24V Power.
4. Operate the DC2228A using the Control Tool software.
Refer to the DC2228A Control Tool section for details.
Briefly, the steps are:
a. Start the Control Tool.
b. Find the IP address assigned to the DC2228A by
DHCP.
c. Configure port devices using I/O Description (IODD)
files.
d. Enter the DC2228A IP address (from Step a), then
click the “Connect” button to connect the Control
Tool software to the DC2228A (Figure 8).
e. Click “Power ON” button to turn on device power.
f. Click “IO-Link” button to begin communication.
5. Alternate configurations:
a. For operation using a direct Ethernet connection not
involving a LAN, refer to the Alternate Configuration
for Fixed IP Address section and Figure 2.
b. For Power over Ethernet (PoE) operation, refer to the
Power over Ethernet section and Figures 3 and 4.
6. Reference material:
a. Refer to the DC2227A Demo Manual for information
and operating details if using this IO-Link device.
7. When finished, disable all ports (using the “Inactive”
and “Power OFF” buttons) and disconnect the Control
Tool (using the “Disconnect” button). Then, turn off the
power supply or PoE source.
