SAFETY PRECAUTIONS

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

(Read these precautions before using this product.)

Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the user’s manual for the CPU module used.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION"

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious consequences. Observe the precautions of both levels because they are important for personal and system safety. Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

[Design Precautions]

WARNING

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 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 Configurator-DP.

(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.

Do not output the "use prohibited" signal as the output signal to an intelligent function module from the programmable controller CPU. Doing so may cause malfunction of the programmable controller system.

H to 5B19H (23072 to 23321)).

[Design Precautions]

WARNING

When a stop error has occurred to the CPU module, the communication status varies depending on the error time output mode setting of GX Works2 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) below 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.

When the QJ71PB92V is mounted in a redundant system, set the watchdog timer for DP-Slaves so that the calculation formula shown in Section 4.8 (5) is satisfied. If the formula is not satisfied, a watchdog timer error occurs in DP-Slaves during system switching.

CAUTION

Do not install PROFIBUS cables together with the main circuit or power lines or bring them close to each other. Keep a distance of 100mm (3.94 inches) or more between them. Failure to do so may result in malfunction due to noise.

A - 2

[Installation Precautions]

CAUTION

Use the programmable controller in an environment that meets the general specifications in the user's manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

To mount the module, while pressing the module mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place. Incorrect mounting may cause malfunction, failure or drop of the module. When using the programmable controller in an environment of frequent vibrations, fix the module with a screw.

Tighten the screw within the specified torque range. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in damage to the product.

Do not directly touch any conductive parts and electronic components of the module. Doing so can cause malfunction or failure of the module.

A - 3

[Wiring Precautions]

WARNING

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 cause the module to fail or malfunction.

CAUTION

Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.

Be sure to place the PROFIBUS cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact.

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.

A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation.

A - 4

[Startup and Maintenance Precautions]

WARNING

Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the connector screws or module fixing screws. Failure to do so may result in electric shock or cause the module to fail or malfunction. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

CAUTION

Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.

Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone System) more than 25cm (9.85 inches) away in all directions from the programmable controller. Failure to do so may cause malfunction.

Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may cause the module to fail or malfunction.

After the first use of the product, do not mount/remove the module to/from the base unit more than 50 times (IEC 61131-2 compliant). Exceeding the limit may cause malfunction.

Before handling the module, touch a grounded metal object to discharge the static electricity from the

OVERVIEW

1.1 Features

The following describes the features of the QJ71PB92V.

(1) DP-Master (Class 1) on PROFIBUS-DP

The QJ71PB92V complies with IEC 61158, and operates as a DP-Master (Class 1) on PROFIBUS-DP systems.

(a) Up to 125 DP-Slaves are connectable

Up to 125 DP-Slaves

exchange of I/O data up to 8192 bytes. ( Section 4.1.1)

* 1 Up to 124 DP-Slaves when QJ71PB92Vs are mounted on main base units in a redundant system

(b) Diagnostic information can be easily acquired

Diagnostic or extended diagnostic information of an error occurred on a DP-Slave during I/O data exchange can be easily acquired using the buffer memory and I/O

signals. ( Section 4.1.2)

can be connected to a single QJ71PB92V, enabling

By sending services (SYNC, UNSYNC, FREEZE, UNFREEZE) to each DP-Slave

in a group, synchronous control of DP-Slave I/O data is available. ( Section

4.1.3)

Table1.1 Descriptions of Services

Service Name Description

This service is for synchronizing the output status of DP-Slaves.

SYNC

UNSYNC This service is for ending the SYNC mode.

FREEZE

UNFREEZE This service is for ending the FREEZE service.

(d) Supporting PROFIBUS-DPV1 and PROFIBUS-DPV2

PROFIBUS-DPV1 and PROFIBUS-DPV2, which are extended versions of PROFIBUS-DP, are supported The QJ71PB92V supports the following:

In the SYNC mode, the output status of a DP-Slave is refreshed

each time it receives the SYNC service.

While no SYNC service is received, the output status is held.

This service is for synchronizing the input status of DP-Slaves.

In the FREEZE mode, the input status of a DP-Slave is refreshed

each time it receives the FREEZE service.

While no FREEZE service is received, the input status is held.

1 - 3

1) PROFIBUS-DPV1

• Acyclic communication with DP-Slaves ( Section 4.2.1)

• Alarm acquisition ( Section 4.2.2)

2) PROFIBUS-DPV2

• Time control function on DP-Slaves ( Section 4.3.1)

1.1 Features

OVERVIEW

(2) I/O data consistency

(3) Easy parameter setup

Using the automatic refresh setting in GX Configurator-DP or dedicated instructions (BBLKRD/BBLKWR) ensures data consistency when reading/writing I/O data from the

QJ71PB92V buffer memory. ( Section 4.5)

Use of GX Configurator-DP enables bus parameters, master parameters, slave

parameters, and various other parameters to be easily set up. ( CHAPTER 6)

OVERVIEW

(4) Swapping of I/O data

The upper and lower bytes can be reversed (swapped) in word units when I/O data is sent or received. This simplifies programming as you no longer need to create a program for swapping

the upper and lower bytes on the QJ71PB92V or DP-Slave. ( Section 4.4)

(5) Mountable on MELSECNET/H remote I/O station

The QJ71PB92V can be mounted on a MELSECNET/H remote I/O station. This allows you to install the QJ71PB92V at a remote site away from the QCPU.

( Section 7.8)

(6) Output status setting for the case of a CPU stop error (Stop/Continue of

I/O data exchange)

For the case of a CPU stop error on a QCPU or remote I/O station where the QJ71PB92V is mounted, whether to stop or continue I/O data exchange with DP-

Slaves can be specified. ( Section 4.6)

(7) Changing DP-Slave setting to reserved station status temporarily

Without modifying the slave parameter in GX Configurator-DP, the station type of DP-

Slaves can be changed to "Reserved station" temporarily. ( Section 4.7) Since there is no need to change slave parameters, changing a DP-Slave setting to a reserved station is easy.

(8) Redundant system can be constructed

(a) Redundancy is available for the QJ71PB92V.

By mounting the QJ71PB92V together with a redundant CPU, a redundant system can be constructed. Even if the QJ71PB92V detects an error, the control and standby systems are

switched each other continuing communications. ( Section 4.8)

(b) System switching is available when an error occurs in the QJ71PB92V or in

communication with a DP-Slave. The systems can be switched when an error occurs in the QJ71PB92V or in communication with a DP-Slave.
