CY3274 QUICK START GUIDE

Using the CY3274 High Voltage 110-240V AC PLC Development Kit

To evaluate this kit, a second PLC low voltage kit is required (CY3272, CY3274, or CY3276). This guide assumes that two CY3274 kits are available

1. Connect the power cable from the AC mains to the AC power

connector on the first CY3274 board. The blue LED turns on.

1. Connect another power cable from the AC mains to the AC power

connector on the second CY3274 board. The blue LED turns on.

1. Install and run PSoC Programmer from the CY3274 Kit CD.

2. Set the device family to CY8C-PLC-LED16P, programming mode to

Reset, Verification to either option, and AutoDetection to On.

3. Open the CY8PLC20_TX.hex file from the Using CY8CPLC20

Application Note folder on the Kit CD.

1. Connect the USB cable from the PC to the MiniProg programmer.

Connect the MiniProg to the ISSP header J21 on node 1.

2. In PSoC Programmer, click the Program button (downward arrow).

When the status says "Programming Successful", remove the Mini-

Prog from the ISSP header.

3. In PSoC Programmer, open the CY8CPLC_TX.hex file. Repeat

steps 1 and 2 for node 2.

1. Connect the LCD Modules to LCD1 header on nodes 1 and 2.

2. On node 1, connect a jumper wire from SW to P26 and a second

jumper wire from VR to P01. The SW header represents the state

of push button S4. The VR header represents the analog voltage

from potentiometer R47.

1. Push the reset button S2 on both nodes. A welcome message

appears on the LCD.

2. When you press the push button (S4) on node 1, analog voltage

from the potentiometer (R47) is transmitted to node 2 and dis-

played on the LCD. The LCD also shows transmission statistics.

CAUTION: High Voltage (Risk of Electric Shock)

All work in powerline communications must be done with extreme care.

Caution must be exercised when using power supplies or power related equipment.
