• 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.

Explanations:
• The received data are stored in CR#49 ~ CR#55.
• The data received every one second are written into D0 ~ D6.
6.10 Application of Data Exchange (2)
Application
Writing the time in RTC in PLC_B into D0 ~ D6 of PLC_A by designating IP by ladder
diagram.
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 the communication. Compile the ladder diagram in the MPU and download
