Explanations:

•The data exchange will be executed every one second.

•Write the IP address of PLC_A into CR#117 and CR#118. The first two IP codes (192.168 = H’C0A8) should be written into CR#118, and the last two IP codes (0.4 = H’0004) into CR#117.

•Set CR#111 as “1” to enable the 8-bit mode. The Modbus instrcution is stored in the low byte of CR#120 ~ CR#247.

•Write Modbus instrcution into CR#120 ~ CR#125. CR#120 is the Modbus address.
