GENERALDESCRIPTION

This isthe user's manual for the AJ71 PB92 PROFIBUS-DPinterfacemodule

(hereafter "AJ71PB92"), which is used to connect a MELSEC-A

series

pro-

grammable controllerto a PROFIBUS-DP network.

The AJ71 PB92 operatesas a master station (class 1) in the PROFIBUS-DP

network.

1.1

SoftwareConfiguration

MELSCAorbsPC

The AJ71 PB92 hasaphysical layer, datalink layer, DDLM, anduser interface

that conformto PROFIBUS-DP, and communicatesdata with the PC CPUby

using a buffer memory.

The mainapplication

PROFIBUS-DPis networksthat execute high-speed

communication at the level

sensors and actuators,andthe AJ71 PB92has

been designed with this in mind: its functions are mainly relatedto data I/O

with slave stations.

Cautions on

System

Configuration

The AJ71PB92 can be installed in any

slot

of the base unit, except for the

following cases:

(1)Avoid installing the AJ71PB92onan extension base unit that hasno

power supply module (A5[

]

type extension base units) since there is a

possibility that the power supplycapacity

will

be insufficient.

you do install the AJ71 PB92 on such anextension base unit, refer to

the user's manualfor the relevantCPU module for details on theappro-

priate power supply and other relevantinformation.

(2)

not install the AJ71 PB92 in the final

slot

of the 7th extension of an

A3CPU.
