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 instruction is stored in the low byte of

CR#120~CR#247.

 Write MODBUS instruction into CR#120~CR#125. CR#120 is the MODBUS address.

 Write the length of the instruction into CR#119.

 Write “1” into CR#115 to start the execution of MODBUS TCP instruction.

 CR#116=2 refers to successful execution. CR#116=3 refers to failed execution.

 If the execution is successful, Y0 on PLC_A will go between On and Off every one second.
