•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.
