4. Switch to “Select Recipients” page. Check all the boxes of “Recipient 1”. Click on “OK” to complete the setting.
5. After all the settings in DVPEN01-SL are completed, compile the ladder diagram in the MPU and download it to the MPU. See below for the program design:

Explanations:
•
If the rising-edge of X0 is triggered, X0 will go from Off to On. Write “1” into CR#3 of
DVPEN01-SL, and the first E-Mail will be sent out.
•
If the falling-edge of X0 is triggered, X0 will go from On to Off. Write “1” into CR#4 of
DVPEN01-SL, and the second E-Mail will be sent out.
•
If the rising-edge of Y0 is triggered, Y0 will go from Off to On. Write “1” into CR#5 of
DVPEN01-SL, and the third E-Mail will be sent out.
•
If the falling-edge of Y0 is triggered, Y0 will go from On to Off. Write “1” into CR#6 of
DVPEN01-SL, and the fourth E-Mail will be sent out.

Ethernet Communication Module DVPEN01-SL
1. See 6.1 for how to set up the communication.
2. Open the setup page of PLC_B and switch to “Data Exchange” page.
3. Check “Enable Data Exchange” box. Select “Program Control” for Execute Mode. Enter IP address of
PLC_A “192.168.0.4” in No. 1 Data Exchange Host IP column. Click on “OK” to complete the setting.

Explanations:
•
The data exchange will be executed every one second.
•
Write the communication address of the destination PLC in CR#28, and DVPEN01-SL will automatically detect by the previous setting that No. 1 IP is “192.168.0.4".
•
Write the data in RTC into CR#29 ~ CR#35.
•
Write “1” into CR#13 to start the data exchange.
•
CR#14 = 2 refers to successful exchange. CR#14 = 3 refers to failed exchange.
5. Compile the ladder diagram for PLC_A and download it to PLC_A.

END
Explanations:
•
The received data are stored in CR#49 ~ CR#55.
•
The data received every one second are written into D0 ~ D6.
