Ethernet Communication Module DVPEN01-SL

DVP-PLC Application Manual

Explanations:

• The data exchange will be executed every one second.

• Write “0” into CR#28, and PLC_B will use CR#25 ~ CR#26 as the IP address of the destination

PLC.

• Write the IP address of PLC_A into CR#25 and CR#26. The first two IP codes (192.168 =

H’C0A8) should be written into CR#26, and the last two IP codes (0.4 = H’0004) into CR#25.

• 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 execution. CR#14 = 3 refers to failed execution.

2. Compile the ladder diagram for PLC_A and download it to PLC_A.

Explanations:

• The received data are stored in CR#49 ~ CR#55.

• The data received every one second are written into D0 ~ D6.

6.11 Application of Data Exchange (3)

Application

Writing the time in RTC in PLC_B directly into D0 ~ D6 of PLC_A without writing in ladder

diagram into PLC_A.

Network

requirement

(1) Adopting static IP.

(2) IP of PLC_A: 192.168.0.4

(3) IP of PLC_B: 192.168.0.5

(4) Update from PLC_B to PLC_A.

1. See 6.1 for how to set up communication.

2. Compile the ladder diagram in the MPU and download it to PLC_B. We do not need to write any

corresponding ladder diagram into PLC_A.
