1 INTRODUCTION

The adapter for FX-485ADP RS485 or the adapter for FX0N-485ADP RS485 (both called 485ADP hereinafter) is designed to link the data between PC and computer by using 485PC-IF.

(1)Data exchange by request from computer

Specified data can be exchanged by sending a request command from the computer to the PC. Except for few functions (global function, on-demand function), the program for data link is not needed at the PC side.

●Batch read / write of all devices (word unit, bit unit) of PC is possible. By reading out the content of each device of the PC, the operating state can be monitored, or the data can be acquired and analyzed. Besides, by writing data into each device, production control and production direction can be effected.

●Remote run / stop of PC is possible. A stopped PC can be started and stopped again from the computer, and therefore the PCs are remote controlled.

●A batch instruction can be issued to all PCs. When one computer and plural PCs are connected, a specific device (special auxiliary relay M8126) can be turned on or off from the computer to all PCs on the circuit. This function is called the global function. This special auxiliary relay M8126 is an exclusive device for

global function.

(2)Data exchange by request from PC

If transmission of emergency data from the PC to the computer is necessary, the PC issues a send request to interrupt in the computer. This function is called on-demand function, and is enabled only when the system is composed of one computer and one PC.
