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.

1.2 System configuration

The system configuration of computer and PC is either 1 : 1 or 1 : n, and for communication with the computer, the RS-485 or RS-422 is used.

(1) Computer and PC by 1 : 1 configuration

: RS-232C interface

FX,FX2C series PC

: RS-485 interface : RS-232C cable

Computer 485ADP Station No.0

485PC-IF

Max. 500m

(2) Computer and PC by 1 : n configuration

In this case, the number of link stations is 16 PCs at maximum for one computer, including the FX series PCs and A series PCs. Such system of data exchange with plural PCs with one computer is called the multi-drop link system.

WIRING

The connecting method with the 485PC-IF is available in two-pair wiring and one-pair wiring, which may be used as follows. As for connection of the 485PC-IF and computer, see the 485PC-IF manual.

●

Two-pair wiring is required when :

① The RS-422 device is incorporated in the system configuration. ② A high speed response is required (message waiting time is desired to be less than 70 ms).

③ The on-demand function is used (however, the system configuration must be 1 : 1). ④ Adding to a system already using two-pair wiring.

*See the 485PC-IF manual.

●

One-pair wiring is required when :

① Adding to a system already using one-pair wiring. ② The system configuration is standardized to RS-485 devices, and two-pair wiring is not needed.
