Example of 16 Bits Data Communication

This system configuration describes an example in which 16-bit buffer length data is sent and
received between the equipment of the terminal specifications. In this example, the ASCII code
saved in the data registers D201 to D205 in the programmable controller sent to the counterpart
equipment, and the data received from the counterpart equipment is saved to the data registers
D301 to D304 in the programmable controller.
