Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

[DESIGN PRECAUTIONS]

DANGER

If a communications error occurs to a device network, the node in such a communications error

•

will be in a state as follows: (1) The master node (QJ71DN91) maintains input data which had been received from the slav e

node before the error occurred.

(2) Whether the slave node's output signal is turned off or maintained is determined by the

slave node's specifications or the parameters set at the master node. When using QJ71DN91 as a slave node, the entered data from master node before the faulty node is

maintained. By referring to communications states of the slave node, arrange an interlock circuit in a sequential program and provide safety mechanism externally of the slave node in order the system to operate safely.

CAUTION

Do not bunch the control wires or communication cables with the main circuit or power wires, or

•

install them close to each other. They should be installed 300 mm (11.8 inch) or more from each other. Not doing so could result in noise that may cause malfunction.

CAUTION

Be careful not to let foreign matters such as sawdust or wire chips get inside the module.

•

These may cause fires, failure or malfunction.

The top surface of the module is covered with protective film to prevent foreign objects such as

•

cable offcuts from entering the module when wiring. Do not remove this film until the wiring is complete. Before operating the system, be sure to remove the film to provide adequate heat ventilation.

Be sure to fix cables leading from the module by placing them in the duct or clamping them.

•

Unless the cables are placed with a duct or clamped, the module or cables could be broken by swinging or moving of the cables or unintentional pulling to cause an operation error result ing from a contact error.

Do not pull cables by holding them with a hand for removing the cables that are connected to the

•

module. To remove a cable having a connector, hold the connector connected to the module with a hand. To remove a cable not having a connector, loosen the screws fastening to connect the module. The cables being pulled while t hey are still connect ed to the module cou ld break the module or cables, or cause an operation error resulting from a contact error.

3.4 Buffer Memory

The buffer memory transfers data between the QJ71DN91 and the PLC CPU. The FROM and TO instructions of the PLC CPU are used to read and write the buffer memory data in the QJ71DN91. The contents of the buffer memory are reset to 0 when the power is turned OFF or when the PLC CPU is reset. However, the "parameter" area is initialized using the saved parameters if the parameters have been saved in the flash ROM.

3.5 Communication Performance

3.5.1 Scan time

The scan time represents the time to wait for responses from all nodes after the QJ71DN91 starts sending requests in the polling or bit strobe communication. The scan time can be calculated using the following expression:

MELSEC-Q

Scan time LS = Σ (TIn + TOn + 0.097) + 0.222

TIn: Transmission time of the reception data from the nth slave. (See the following

expression for details.)

TOn: Transmission time of the transmission data from the nth slave. (See the following

expression for details.) Σ : Indicates adding values in ( ) of all slave nodes (except for the reserved nodes). BR: Coeffici en t co rr e spo nding to the baud rat e

500kbaud = 1, 250kbaud = 2, 125kbaud = 4

BR + 0.1 (module: ms)

(1) How to calculate TIn

1) When the length of reception data from the nth slave is 8 bytes or less : TIn=BT + BTa

2) When the length of reception data from the nth slave is 9 bytes or more : TIn= (BT + BTa

whereas, a = reception data length divided by 7 (round down below

reception data length (bytes)

8 + 0.190) a + {BT + BTa (b+1) + 0.450}

3.5.2 Communication cycle

The communication cycle is the time interval between the moment a polling or a bit strobe request is sent to a slave node and the moment another request is sent to the same node. A different communication cycle can be set for each node by setting the production inhibit time parameter. The communication cycle for each slave node can be calculated using the following expression:

Communication cycle LC = LS + production inhibit time (module: ms)

3.5.3 Transmission delays (1) Input transmission delay

The input transmission delay can be calculated using the following expressions:

4.2 Loading and Installation

The following section explains the precautions when handling the QJ71DN91 from the time they are unpacked until they are installed. For more details on the loading and installation of the module, refer to the User's Manual for the PLC CPU used.

4.2.1 Handling precautions

(1) Do not drop the module casing or connector, or do not subject it to strong impact.

(2) Do not remove the printed-circuit board of each module from its case. This may

cause a failure in the module.

(3) Be careful no t t o le t fo re ig n ob je ct s su ch as wi re c hi p s get in si de the module.

These may cause fire, breakdown or malfunction.

MELSEC-Q

(4) The top surface of the module is covered with a protective film to prevent foreign

objects such as wire chips from entering the module during wiring. Do not remove this film until the wiring is complete. Before operating the system, be sure to remove the film to provide adequate heat ventilation.

(5) Tighten the mounting screws using the torque within the range listed below. If the

screws are not tightened securely, it may cause short-circuit, breakdown or malfunction.

Module mounting screws (M3 screws) 36 to 48 N•cm DeviceNet connector mounting screws 35.3 to 48.0 N•cm DeviceNet connector wiring mounting screws 60.8 to 82.3 N•cm

(6) To mount the module on the base unit, securely insert the module mounting

latches into the mounting holes on the base unit. Improper installation may result in a malfunction or breakdown of the module, or may cause the module to fall off.

4.3.2 Node number setting switch

The following explains the node number setting switch of the QJ71DN91.

Table 4.2 Description of the node number setti ng sw i tch

Name Description

Node number setting switch

Sets the node number of the module. (Setting at the time of shipment from the factory:

0) Since the node number is recognized when the module is powered on or reset, do not change the node number during module operation. If changed, the "ERR" LED will flash. Setting range: 0 to 63 (if a number other than 0 to 63 is set, the "ERR" LED will be lit.)

Exercise caution so that the node number does not duplicate with that of other

node.

POINT

If the module is used as both the master and slave nodes, the same node number is used for the master and slave nodes. Although the node number can be set between 0 and 63, smaller node numbers have higher communication priority as a communication characteristic of a DeviceNet network. Thus, set the smallest node number for the master node as much as possible.

)

MELSEC-Q

The following two auto configuration types are available:

• All configuration: Searches all the slave nodes in the network having node

numbers 0 to the maximum detection node number, except the local node number, and saves them in the "parameters for the master function" area. The areas after the detected slave nodes will be cl ea re d.

• Additional configuration: Searches all the slave nodes in the network having

node numbers 0 to the maximum detection node number, except the local node number and the slave nodes currently being set, and saves them in the "parameters for the master function" area. The areas

after the det ect ed save nod e s will no t be cle a red. The auto configuration is performed in the following sequence: (a) Set the auto configuration type in the "auto configuration operation settings"

area. (b) Set the auto configuration request (Y15) to ON. (c) The auto configuration result is stored in the "parameters for the master

function" area.

The GX Configurator-DN is an add-in package for GX Developer Version 4 or later. Therefore, install GX Configurator-DN into the personal computer where the GX Developer Version 4 or later product has already been installed.

MELSEC-Q

(3) About display-screen errors whil e using the i ntel lig ent function

module utility

There may be cases in which the screen will not properly display while the intelligent function module utility is being used, due to a lack of system resources. If this occurs, close the intelligent function module utility first and then GX Developer (program, comments, etc.) and other applications. Next, restart GX Developer and the intelligent function module utility.

(4) To start the intelligent function module utility

(a) In GX Developer, select "QCPU (Q mode)" for the PLC series and specify

the project. If something other than "QCPU (Q mode) " is selected for the PLC series, or if the project is not specified, the intelligent function module utility will not start.

(b) Multiple intelligent function module utilities can be started.

However, the [Open file]/[Save file] intelligent function module's parameter operations can only be performed by a single intelligent function module utility. Other intelligent function module utilities can perform the [Monitor/test] operation only.

(5) How to switch screens when two or more intel l igent function

module utilities are started

When two or more intelligent function module utility screens cannot be displayed side by side, use the task bar to change the intelligent function module utility screen so that it is displayed on top of other screens.

(6) About the number of parameters that ca n be set i n GX

Configurator-DN

The number of parameters that can be set by the GX Configurator for an intelligent function module installed in the CPU module and in a remote I/O station of the MELSECNET/H network system is limited.

Intelligent function module installation object

Q00J/Q00/Q01CPU 512 256 Q02/Q02H/Q06H/Q12H/Q25HCPU 512 256 Q12PH/Q25PHCPU 512 256 MELSECNET/H remote I/O station 512 256

Maximum number of parameter settings

Initial setting Automatic refresh setting

For example, if multiple intelligent function modules are installed in a remote I/O station, set the GX Configurator so that the number of parameter settings of all the intelligent function modules does not exceed the maximum number of parameter settings.The total number of parameter settings is calculated separately for the initial setting and for the automatic refresh setting. The number of parameter settings that can be set for one module in the GX Configurator-DN is as shown below.

Object Module Initial setting Automatic refresh setting

QJ71DN91 0 (Not used) 18 (Maximum number of settings)

Example) Counting the number of parameter settings in the automatic refresh

setting

The number of settings in this one line is counted as one setting. The number of settings is not counted by columns. Add up all the setting items in this setting screen, then add them to the total for the other intelligent function modules to get a grand total.
