1. 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.

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
of PROFIBUS-DPis networksthat execute high-speed
communication at the level
of sensors and actuators,andthe AJ71 PB92has
been designed with this in mind: its functions are mainly relatedto data I/O
with slave stations.

1. GENERAL DESCRIPTION MELSEGA
\
12 Features of the AJ71 PB92
By setting parameters usingthe utility software package,the AJ71PB92 can
be used as a
PROFIBUS-DP master station (class 1).
By using X and Y I/O signalsand the buffer memory,the AJ71PB92 can
exchange
1/0 data with slave stations.
Thenetworkcommunicationspeed can be
selected from among the
following options by
DIP switch setting: 9.6,19.2,93.75,187.5, 500,
1500
kbps.
The module’s station number can be set with a rotary switch
(1 or 2).
By
using X and Y I/O signals and thebuffer memory, the AJ71PB92 can
read fault informationfrom slave stations.

The
AJ7l PB92 has been developed as abuilding-block type communication
module for use
with MELSEC-A series equipment.
An IBM PC/AT or 100% compatibleis used as the operationcontrol terminal
and
a utility software package has been developedto run on it.

24 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.
If 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)
Do not install the AJ71 PB92 in the final slot of the 7th extension of an
A3CPU.
