SAFETY PRECAUTIONS
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced
in this manual. Also pay careful attention to safety and handle the module properly.
These precautions apply only to Mitsubishi equipment. Refer to the CPU module user’s manual for a
description of the PLC system safety precautions.
These •SAFETY PRECAUTIONS •classify the safety precautions into two categories: “DANGER” and
“CAUTION”.
DANGER Procedures which may lead to a dangerous condition and cause death or
serious injury if not carried out properly.
CAUTION Procedures which may lead to a dangerous condition and cause superficial
to medium injury, or physical damage only, if not carried out properly.
Depending on circumstances, procedures indicated by CAUTION may also be linked to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it whenever necessary. Always
forward it to the end user.
[DESIGN PRECAUTIONS]
DANGER
zWhen a communication error occurs in the PROFIBUS network, the status of the faulty station is as follows.
Configure an interlock circuit in the sequence program using the communication status information (input
X1, buffer memory 2040 to 2079) so that the system can operate safely.
Erroneous outputs and mis-operation could cause accidents.
(1) The input data of the master station maintains the data before abnormality of the communication.
(2) When the master station is down, the output state of each slave station will be in accordance with the
parameter settings.
(3) When any slave station is down, the output state of other slave stations will be in accordance with the
parameter settings of the master station.
zIf a stop error occurs in the CPU module, the communication status is as described below.
(1) Communication with the slave station is stopped.
(2) For the input data received from the slave station, the values at CPU module stop error occurrence are
held.
(3) The output data sent from the AJ71PB92D/A1SJ71PB92D to the slave station are cleared.
CAUTION
zWhen the PROFIBUS cable is laid, do not lay it close to main circuits or power lines.
They should be installed 100mm(3.9inch) or more from each other.
Not doing so could result in noise that would cause malfunctioning.

[INSTALLATION PRECAUTIONS]
CAUTION
zUse the module in the environment given in the general specifications of the CPU module’s User’s Manual.
Using the module outside the range of the general specifications may result in electric shock, fire or
malfunctioning, or may damage or degrade the module.
zInsert the tabs at the bottom of the module into the mounting holes in the base unit before installing the
module. (The AnS series module shall be fastened by screws in the base unit at the specified torque.)
Not installing the module correctly could result in malfunctioning, breakdowns or pieces of the product falling
zTighten the fixing screws of the PROFIBUS cable with the specified torque. If the screws are loose, it could
result in malfunction of the module.
zDo not touch the conductive area or electric parts of the module.
Doing so may cause module malfunctioning or breakdowns.
[WIRING PRECAUTIONS]
CAUTION
zSwitch all phases of the external power supply of the PLC system off before connecting the PROFIBUS
cable. Not doing so could cause failure or malfunctioning of the module.
zBe careful not to let foreign matter such as filings or wire chips get inside the module. These can cause fire,
breakdowns and malfunctioning.
zThe PROFIBUS cable which is connected to the module must be protected with a duct or secured in
position with clamps.
Unless the cable is thus protected or secured, the module or the cable could be damaged when the cable
swings, moves or it is strained with careless pulls, or it could cause malfunction when the cable contacts
with any undesirable objects.
zWhen disconnecting the PROFIBUS cable from the module, do not pull by holding the cable section. To
disconnect the cable, make sure to hold the connector which is coupled with the module. Do not attempt to
pull the cable to disconnect it from the module. It could damage the module or the cable, or cause
malfunction due to a poor contact of the cable.
[STARTING AND MAINTENANCE PRECAUTIONS]
DANGER
zSwitch all phases of the external power supply off before cleaning.
Not doing so could cause electric shock.

CAUTION
zNever disassemble or modify the module.
This may cause breakdowns, malfunctioning, injury and/or fire.
zSwitch all phases of the external power supply off before mounting or removing the module. If you do not
switch off the external power supply, it will cause breakdowns or malfunction of the module.
zSet the ON/OFF select switch of the terminal resistor before the operation.
If the setting is switched during the operation, network error may occur, or error detection may not be
performed by error.
zBefore handling the module, always touch grounded metal, etc. to discharge static electricity from the
human body.
Failure to do so can cause the module to fail or malfunction.
[OPERATING PRECAUTIONS]
DANGER
zDo not write data into the "not usable" of the buffer memory of special function modules. Also, do not output
the "not usable" signal as the output signal to a special function module from the PLC CPU. Writing data
into the "not usable area" or outputting an "not usable" signal may cause system malfunctions in the PLC.
CAUTION
zThe online operations conducted for the CPU module being operated (especially when changing data or
operation status), shall be conducted after the manual has been carefully read and a sufficient check of
safety has been conducted.
Operation mistakes could cause breakdowns to or malfunction of the module.
[DISPOSAL PRECAUTIONS]
CAUTION
zWhen disposing of this product, treat it as industrial waste.

1. OVERVIEW
This is the user's manual for the AJ71PB92D/A1SJ71PB92D PROFIBUS-DP interface module
(hereafter abbreviated as " AJ71PB92D/A1SJ71PB92D. When explain separately, however,
abbreviated as AJ71PB92D, A1SJ71PB92D), which is used to connect a MELSEC-A/QnA/Q series
programmable controller to a PROFIBUS-DP network.
The AJ71PB92D/A1SJ71PB92D operates as a master station (class 1) in the PROFIBUS-DP network.

The AJ71PB92D/A1SJ71PB92D has a physical layer, data link layer, DDLM, and user interface that
conform to PROFIBUS-DP, and communicates data with the PLC CPU by using a buffer memory.
The main application of PROFIBUS-DP is networks that execute high-speed communication at the
level of sensors and actuators, and the AJ71PB92D/A1SJ71PB92D has been designed with this in
mind: its functions are mainly related to data I/O with slave stations.

1.2 AJ71PB92D/A1SJ71PB92D Features
(1) Operates as a PROFIBUS-DP master (class 1) station.
(2) Makes possible the exchange of input and output data to and from the slave station
without the need to be aware of the PROFIBUS-DP protocol by using I/O signals X/Y and
the buffer memory.
(3) Supports 3M, 6M, 12M [bps] network communication speeds in addition to the 9.6k, 19.2k,
93.75k, 187.5k, 500k, and 1.5M [bps] supported by the AJ71PB92D/A1SJ71PB92D. These
can be selected using a configurator.
(4) Station Nos. from 0 to 125 can be set using the configurator.
(5) Trouble information can be read from the slave station using the I/O signal X/Y and the
buffer memory.
(6) The global control function makes it possible to maintain all slave I/O at the same time. In
addition, this can also be canceled.
(7) The module contains a self-diagnosis function that can be used to test the hardware such
as the internal memory.

When A1SJ71PB92D (software version D or earlier) is used, write is disabled and the
max. data length is 32 bytes each for input and output.
(2) Precautions for using the parameters preset for extended service mode to operate the
module in normal service mode.
The following table gives the operating conditions (conditions per one slave station) for the time
when the parameters preset for the extended service mode are used to operate the
AJ71PB92D/A1SJ71PB92D preset for the normal service mode/extended service mode.

(3) In either of the following cases, the AJ71PB92D/A1SJ71PB92D buffer memory must be
accessed by a sequence program when the module ready signal X1D of the
AJ71PB92D/A1SJ71PB92D is ON.
•The operation mode is changed using Y11/X11 in the sequence program.
•Parameter setting is made with ProfiMap connected to other than the RS-232C port of
the AJ71PB92D/A1SJ71PB92D. (For example, parameter setting is made with ProfiMap
connected to the RS-422/RS-232 connector of the CPU module.)
If the buffer memory is accessed with the X1D status ignored, the CPU module may detect
the "SP UNIT DOWN" error, stopping the sequence operation.

2. SYSTEM CONFIGURATION MELSEC-A
2-6
(4) Do not make parameter setting via buffer memory and parameter setting from the RS-
232C port of the AJ71PB92D/A1SJ71PB92D at the same time.
If they are made simultaneously, ProfiMap which started parameter write earlier wins the
parameter write right after the operation mode is changed to the parameter setting mode, and
the other ProfiMap cannot perform parameter write and detects an error.
This status will be automatically cleared 15 seconds after completion of parameter write if
parameter write via the CPU module is valid, or 3 seconds after completion of parameter write
if parameter write from RS-232C is valid.
(5) Do not make simultaneous access to the AJ71PB92D/A1SJ71PB92D from multiple
ProfiMap's.
If such access is made, the AJ71PB92D/A1SJ71PB92D may not be accessed properly.
(6) If remote parameter setting is performed from MELSEC ProfiMap to the
AJ71PB92D/A1SJ71PB92D which is making data exchange, note that PROFIBUS data
exchange will stop during parameter setting.
(7) In a system where remote parameter setting is made from MELSEC ProfiMap, do not
execute the mode changing function using the program.
If the mode changing function is executed in the program, an interlock with the remote
parameter setting is not provided and therefore the mode may not be changed.
