[DESIGN PRECAUTIONS]
DANGER
•When a communication error occurs in the PROFIBUS-DP, 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 (7F8H) to 2079 (81FH)) 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.
•If 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) For the output data sent from the A1SJ71PB92D/AJ71PB92D to the slave station are cleared.

[DESIGN PRECAUTIONS]
CAUTION
•When 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
•Use the PLC in an environment that meets the general specifications contained in the CPU user's manual.
Using this PLC in an environment outside the range of the general specifications may cause electric shock,
fire, malfunction, and damage to or deterioration of the product.
•Insert 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.
•Tighten the fixing screws of the PROFIBUS cable with the specified torque.
If the screws are loose, it could result in malfunction of the module.
•Be sure to shut off all phases of the external power supply used by the system before mounting or removing
the module.
Not ding so may cause electric shock or damage to the module.
•Do not touch the conductive area or electric parts of the module.
Doing so may cause module malfunctioning or breakdowns.

[WIRING PRECAUTIONS]
CAUTION
•Be sure to shut off all phases of the external power supply used by the system before wiring PROFIBUS
cables. If you not switch off the external power supply, it will cause failure or malfunction of the module.
•Be careful not to let foreign matter such as filings or wire chips get inside the module. These can cause fire,
breakdowns and malfunctioning.
•Be sure to place the PROFIBUS cables in a duct or clamp them.If not, dangling cables may be shifted or
inadvertently pulled, resulting in damages to the module or cables or malfunctions due to poor cable contact.
•When 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

could cause electric shock.
CAUTION
•Never disassemble or modify the module.
This may cause breakdowns, malfunctioning, injury and/or fire.
•Be sure to shut off all phases of the external power supply 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.
•Set 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.
•Before 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
•Do not write data into the "System area (use prohibited)" of the buffer memory of special function modules.
Also, do not output the "Use prohibited" signal as the output signal to a special function module from the PLC
CPU. Writing data into the "System area (use prohibited)" or outputting an "Use prohibited" signal may cause
system malfunctions in the programmable controller.
CAUTION
•The 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.

or AJ71PB92D (B or later).
When A1SJ71PB92D (software version E or earlier) is used, write is disabled.
*2 For the A1SJ71PB92D of software version D or earlier, the extended service mode (MODE E)
is not applicable.
(4) Combining with MELSECNET/10, MELSECNET/B, and MELSECNET(II)
The A1SJ71PB92D/AJ71PB92D does not work on a remote I/O station of MELSECNET/10,
MELSECNET/B, and MELSECNET(II).

2.3 Precautions for Configuring a System
(1) Precaution for parameter writing
(a) If a parameter is written to the A1SJ71PB92D/AJ71PB92D that is exchanging I/O data, the
I/O data communication is suspended.
It is restarted after completion of parameter writing.
(b) Do not change the operation mode from the sequence program during parameter writing.
Doing so may disable proper station number setting or mode change.
(c) Do not write parameters from multiple GX Configurator-DPs and MELSEC ProfiMap to a
single A1SJ71PB92D/AJ71PB92D at the same time.
Doing so makes the parameter values of the A1SJ71PB92D/AJ71PB92D incorrect.
(d) Do not write parameter settings at the same time via the RS-232 interface of the
A1SJ71PB92D/AJ71PB92D and via the RS-232/RS-422 interface of the CPU module.
Doing so may result in incorrect parameter setting and if this is attempted, parameters
cannot be written.
In such a case, write the parameters again after 15 seconds or more has elapsed.
(2) Precautions for using the parameters preset for extended service mode (MODE E) to operate the
module in normal service mode (MODE 0).
The A1SJ71PB92D/AJ71PB92D enters normal service mode (MODE 0) and operates using
exchange data of up to 32 bytes per slave station.
When using a data length of 33 bytes or more per slave station, set the
A1SJ71PB92D/AJ71PB92D to the extended service mode (MODE E).

(3) When reading/writing the buffer memory
Make sure that the READY signal (X1D) is ON when reading/writing the
A1SJ71PB92D/AJ71PB92D buffer memory from the sequence program for the following:
• To switch over the operation mode with Y11/X11, using the sequence program.
• To set GX Configurator–DP or MELSEC ProfiMap parameters through the RS-232/RS-422
interface of the CPU module
If the status of module READY signal (X1D) is ignored and data is read from or written in the
buffer memory, the CPU module may detect an “SP UNIT DOWN” error to stop the sequence
calculation.
