Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or slight
personal injury or physical damage.
A-1
[Design Precautions]
DANGER
z When a communication error occurs on PROFIBUS-DP, the status of the
faulty station is as shown below.
Create an interlock circuit in the sequence program using the communication
status information to ensure the system operates safely (Input X1, buffer
memory 5A20
H to 5B19H (23072 to 23321)).
An erroneous output or malfunction may cause accidents.
(1) The QJ71PB92V holds the input data before the communication failure.
(2) When the QJ71PB92V has gone down, the output status of each DP-Slave
is dependent on the QJ71PB92V parameter setting on GX ConfiguratorDP.
(3) When a DP-Slave has gone down, the output status of the other DP-
Slaves is dependent on the QJ71PB92V parameter setting on GX
Configurator-DP.
z Do not output the "use prohibited" signal as the output signal to an intelligent
function module from the programmable controller CPU.
Writing data into the "system area"or outputting a signal for "use prohibited"
may cause system malfunction in the programmable controller.
z When a stop error has occurred to the CPU module, the communication
status varies depending on the error time output mode setting of GX
Developer as shown below.
Set the communication status for when a stop error has occurred to the CPU
module according to the system specifications.
Note that, if the QJ71PB92V is mounted to a redundant system, it operates as
described in (1) regardless of the setting.
(1) When "Error time output mode" is set to "Hold".
(a) Since the communication with the DP-Slave is continued, values at the
time of the CPU module stop error occurrence are held as the output
data sent to the DP-Slave from the QJ71PB92V.
(b) Input data received from DP-Slaves are updated into the buffer memory
of the QJ71PB92V.
(2) When "Error time output mode" is set to "Clear".
(a) Communications with DP-Slaves are interrupted, and output data are
not sent.
(b) Input data received from DP-Slaves are held in the buffer memory of
the QJ71PB92V.
A-2
[Design Precautions]
DANGER
z When the QJ71PB92V is mounted in a redundant system, set the watchdog
timer for DP-Slaves so that the calculation formula shown in PROFIBUS-DP
Master Module User's Manual. If the formula is not satisfied, a watchdog timer
error occurs in DP-Slaves during system switching.
CAUTION
z Do not bunch PROFIBUS cables with the main circuit or power wires, or install
them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.
[Installation Precautions]
CAUTION
z Use the programmable controller under the environment specified in the
user's manual of the CPU module to be used.
Using this programmable controller in an environment outside the range of the
general specifications could result in electric shock, fire, erroneous operation,
and damage to or deterioration of the product.
z While pressing the installation lever located at the bottom of module, insert the
module fixing tab into the fixing hole in the base unit until it stops. Then,
securely mount the module with the fixing hole as a supporting point.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much
vibration, tighten the module with a screw.
z Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
to the screw or module.
z Completely turn off the externally supplied power used in the system before
mounting or removing the module.
Not doing so could result in damage to the product.
A-3
[Installation Precautions]
CAUTION
z Do not directly touch the module's conductive parts or electronic components.
Touching the conductive parts could cause an operation failure or give
damage to the module.
[Wiring Precautions]
DANGER
z Be sure to shut off all phases of the external power supply used by the system
before wiring PROFIBUS cables.
Failure to do so may result in failure or malfunctions of the module.
CAUTION
z Be sure there are no foreign substances such as sawdust or wiring debris
inside the module.
Such debris could cause fires, damage, or erroneous operation.
z 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.
z When disconnecting the PROFIBUS cable, do not pull it by holding the cable
part.
Be sure to hold its connector which is plugged into the module.
Pulling the cable with it connected to the module may damage the module
and/or cable, or cause malfunctions due to poor contact of the cable.
z The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.
A-4
[Startup and Maintenance Precautions]
DANGER
z Before cleaning, be sure to shut off all phases of the external power supply
used by the system.
Failure to do so may cause electrical shocks.
CAUTION
z Do not disassemble or modify the module.
Doing so could cause trouble, erroneous operation, injury, or fire.
z Use any radio communication device such as a cellular phone or a PHS
phone more than 25cm (9.85 inch) away in all directions of the programmable
controller.
Not doing so can cause a malfunction.
z Completely turn off the externally supplied power used in the system before
mounting or removing the module.
Not doing so could result in damage to the product.
z Do not mount/remove the module to/from the base unit or terminal block more
than 50 times (IEC 61131-2 compliant), after the first use of the product.
Failure to do so may cause module malfunctions.
z Before touching the module, always touch grounded metal, etc. to discharge
static electricity from human body, etc.
Not doing so can cause the module to fail or malfunction.
[Disposal Precautions]
CAUTION
z When disposing of this product, treat it as an industrial waste.

3.1 Handling precautions
The following are precautions for handling the QJ71PB92V as a unit.
(1) Do not drop the module case or subject it to heavy impact since it is
made of resin.
(2) Do not remove the printed-circuit board of each from its case.
This may cause a failure in the module.
(3) Be careful not to let foreign objects such as wire burrs enter the
module during wiring.
In the even any foreign object enters, remove it immediately.
(4) The module has an ingress prevention label on its top to prevent
foreign matter, such as wire offcuts, from entering the module during
wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because
of heat dissipation.
(5) Before touching the module, always touch grounded metal, etc. to
discharge static electricity from human body, etc.
Not doing so can cause the module to fail or malfunction.
(6) Tighten the screws such as module fixing screws within the following
ranges.

5.2 Wiring precautions
As one of the requirements to give full play to QJ71PB92V’s functions
and make up the system with high reliability, it is necessary to have an
external wiring unsusceptible to an influence of noise.
The following gives the precautions for external wiring of the
QJ71PB92V.
(1) Communication cable wiring
Do not install the QJ71PB92V communication cable together with
the main circuit, power lines and/or load carrying wires for other then
the programmable controller, or bring them close.
Doing so may cause the QJ71PB92V to be affected by noise and
surge induction.
(2) Wirings from programmable controller and I/O modules
Keep the PROFIBUS cable away from I/O module cables as much
as possible.
