!

WARNING

• For the operating status of each station after a communication failure, refer to Section 8.2.6 in this manual. Failure to do so may result in an accident due to an incorrect output or malfunction.

• When changing data of a running programmable controller from a peripheral connected to the CPU module or from an external device such as a personal computer connected to an intelligent function module, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other controls to a running programmable controller (such as program modification or operating status change), read relevant manuals carefully and ensure the safety before the operation. Especially, in the case of a control from an external device to a remote programmable controller, immediate action cannot be taken for a problem on the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

[Design Precautions]

!

WARNING

• Do not write any data to the "system area" of the buffer memory in each intelligent function

module. Also, do not turn on any "use prohibited" signal that is output from the CPU module to the intelligent function module. Writing data to the "system area" or outputting a "use prohibited" signal may cause malfunction of the programmable controller system.

• When setting auto refresh parameters, specify "Y" for the remote output RY refresh devices.

Specifying any other than "Y" (for example, M or L) will hold the previous device status in the case of a CPU stop. For how to stop a data link, refer to Section 8.3.8.

• Disconnection of a CC-Link dedicated cable may make the line condition unstable, causing

communication errors on multiple stations on the network. Configure an interlock circuit in the program so that the system will operate safely even if these communication errors occur on multiple stations. Failure to do so may result in an accident due to an incorrect output or malfunction.

[Design Precautions]

1 CC-Link SYSTEM

1.1 About CC-Link System

The CC-Link system is a system that connects distributed modules such as I/O modules, intelligent function modules, and special function modules using dedicated cables so that these modules can be controlled by a programmable controller CPU.

(1) By connecting each module separately to equipment such as a conveyor line or a

machine, the number of wires can be reduced in the entire system.

(2) Each module’s on/off information of input/output and numeric data can easily be

sent and received at high-speed.

(3) By connecting multiple programmable controller CPUs, a simple distributed

system can be configured.

(4) Since various devices from Mitsubishi's partner manufacturers can be connected,

the system can provide flexible solutions depending on the user’s requirements.

Performs on/off data and numeric data communication with local

stations.

Performs communication with intelligent device station, by cyclic

transmission, and transient transmissions.

(2) List of the "functions for improving system reliability"

Disconnects a slave station that cannot continue the data link

due to a reason such as power off, so that data link can continue

among normal slave stations only.

When a slave station, which has been disconnected from the

network due to a reason such as power off, returns to the normal

status, it automatically joins the data link.

Sets whether to stop or continue the data link when an error that

stops the operation occurs at the master station programmable

controller CPU in the system that has no standby master station.

When "Continue" is set, the diagnostics of the master station can

be performed from local stations.

Sets whether to clear or hold the input data (remote input RX)

from a station that detected a data link error due to a reason

such as power off.

Sets whether to refresh or forcibly clear output data (remote

output RY) to the slave stations when the programmable

controller CPU comes to STOP.

When "Clears Compulsorily" is set, the remote output RY turns

off when the operation stops due to STOP of programmable

controller CPU or due to an error occurrence.

Continues the data link by switching the control to the standby

master station when a problem occurs in the master station.

Starts data link when either of the master or standby master

station is turned on.

Guarantees the consistency of the cyclic data for each slave

station.

Guarantees the 32-bit data of the remote register (RWr/RWw)

(3) List of the "handy functions"

Programs for the initial setting become unnecessary, since the initial settings in the remote device station are set at the network parameter. The initial settings in the remote device station can be configured easily.

Since the interrupt program of the programmable controller CPU is executed according to the established event issuance conditions, high speed data receive processing can be made without being influenced by the sequence scan.

The CC-Link starts automatically, only by turning the power on, and the operation at the system construction can be checked.

By setting slave stations that will be connected in the future as reserved stations, they will not be treated as data link faulty stations.

Prevents slave stations that may be powered off in the system configuration from being treated as data link faulty stations by setting the network parameters.

Changes slave stations without detecting errors during online operation. Also, prevents slave stations, which are turned off in the system configuration, from being treated as data link faulty stations temporarily.

Selects whether to synchronize or not the link scan with sequence scan. In the synchronous mode, the link scan is performed synchronously with the sequence scan. Therefore, the output data can be sent in high speed. In the asynchronous mode, the link scan is performed not synchronized to the sequence scan. Therefore, a high speed link scan can be performed independent of the sequence scan.

Stops or restarts the data link that is being executed. By stopping the data link, the program debug can be performed efficiently, since data from other stations are not received, and data are not sent from the host station.

Allows the I/O points of the remote I/O stations to be selected from among 8 points, 16 points and 32 points, reducing the number of reserved points. The refresh device points of the programmable controller CPU and the link refresh time can be saved.

Master station duplication errors can be canceled without turning the power supply off to on, or without resetting the programmable controller CPU.

When the host station is a local station or a standby master station, an auto following occurs according to the transmission speed of the master station, what eliminates setting errors of the transmission speed.

Logs the data link status of all stations. When multiple stations repeat normal/faulty, or when determined stations and later repeat normal/faulty, this function enables easy identification of the causes, such as contact failure of the cable, or the noise occurrence location.

(2) When the ver.2 compatible slave station is added or deleted, the refresh devices

of the programmable controller CPU will vary by the number of points set to the added or deleted slave station in the slave stations of the station numbers after the added or deleted slave station. Confirm the varying number of points in Section 3.2 (1).

(3) In the remote net additional mode, the ver.2 compatible slave station must be

placed in the latter half as described in (1). When there is a possibility that ver.1 compatible slave stations will be added in the future in the remote net additional mode, set multiple reserved stations after the ver.1 compatible slave station to ensure ease of expanding the system.

(4) For the system that includes a standby master station, it is recommended to

change for the remote net ver.2 mode. When the remote net additional mode is used, the program for the standby master station must be corrected.

5.2.3 Precautions on the system configuration

The system should be designed with the following considerations to prevent mis-input from the remote I/O modules:

(1) When powering on or off

Start the data link after turning on the power to remote I/O modules. Turn off the power to remote I/O modules after stopping the data link.

(2) During momentary power failure of remote I/O modules

When a momentary power failure occurs in the power (24 V DC) supplied to remote I/O modules, mis-input may occur.

(a) Cause for mis-input due to a momentary power failure

The remote I/O module hardware uses the power by internally converting the module power (24 V DC) to 5 V DC. When a momentary power failure occurs in a remote I/O module, the following condition occurs: (Time for the 5 V DC power in the remote I/O module to turn off) > (Response time for input module on

off) Therefore, mis-input occurs when a refresh is performed within the time indicated by 1) in the figure below.

1)

Remote I/O module (module power supply and input external supply power)

Remote I/O module (internal 5 V DC)

Input (Xn)

When the input external power supply turns OFF, the input (Xn) turns OFF after the response time for the input module to change from ON to OFF.

5 - 4 5 - 4

(b) Countermeasure for mis-input

To the power supply module, the stabilized power supply and the external supply power of AC input, connect power cables from the same power

source.

5 SYSTEM CONFIGURATION

For AC input

REMARK

When supplying power from a single power source to multiple remote I/O modules, select the proper type of cable and perform the wiring, taking into account a voltage drop. Connections can be established if the receiving port voltage at the remote I/O module is within the specified range of the remote I/O module to be used.

5 SYSTEM CONFIGURATION

(3) Access to station No.64

(a) To a local station of No. 64, other station access from GX Works2 or GOT

is not allowed. If the station No. is changed to any of 0 to 63, other station access is executable.

(b) From the CC-Link board, other station access is not allowed to access a

local station or intelligent device station whose station No. is 64. If the station No. is changed to any of 0 to 63, other station access is executable.

(4) Precautions on the retry count setting for use of dedicated

instructions

Note that some dedicated instructions are not applicable to the retry count setting. For details, refer to Section 9.1.1 (3). For the retry count setting for use of dedicated instructions, there are no restrictions on CPU module models.

7 PARAMETER SETTINGS

POINT

(1) The network parameters other than operation setting, station No., mode and

transmission speed are also valid when the programmable controller CPU is switched from STOP to RUN.

(2) When changing the parameters and settings of master station or slave station,

stop the data link at the master station and then make the changes.

(3) When changing the parameters and settings of slave station, change the

parameters of the master station along with the slave station change.

(4) For the automatic refresh parameter setting, set the start device only. Devices

are automatically assigned up to the last station number including reserved stations and occupied stations. In the following system configuration example, the last station number is "12". Therefore, total of remote I/O points is 384 (32 register points is 48 (4

12 = 48). If refresh device of remote input (RX) is set

12 = 384) and total of remote

to "X1000" and that of remote register (RWr) is set to "W0", the end devices will be "X117F" and "W2F" respectively.

they do not overlap with the device numbers used on the other networks, etc.

(6) When setting X and Y as refresh devices, set I/O numbers higher than the I/O

numbers used for I/O modules and intelligent function modules.

7 - 7 7 - 7

7 PARAMETER SETTINGS

(1) Station number setting

The following explains how to set the station numbers for the master station and slave stations.

Specify the station numbers according to the following conditions.

(a) Specify sequential station numbers

Station numbers can be specified regardless of the order in which the stations are connected. For a module occupying two or more stations, specify the first station number.

(b) Specify unique station numbers

If duplicate station numbers are specified, an installation error occurs. (Error codes are stored in SW0069)

[Setting example] When station numbers are specified with one station number

skipped

POINT

Specify unassigned station numbers as reserved stations. An unassigned station number will be treated as a "data link faulty station" (can be verified with link special registers SW0080 to SW0083).

7 - 8 7 - 8

7 PARAMETER SETTINGS

(2) Transmission speed

Set the transmission speed of the master station, the local station and the standby master station.

For using the module as a local station or standby master station, the transmission speed can be set to "Auto following". In that case, since the local station or standby master station follows the transmission speed of the master station automatically, no transmission speed setting error will occur.

The transmission speed can be confirmed with the "B RATE" LED, on the front of the module. (Refer to Chapter 2)

POINT

(1) When the transmission speed is set to "Auto Following", it takes about five

seconds for the transmission speed to be determined after powered on. So does when a station is reconnected to the network after disconnection.

(2) The transmission speed that can be set varies depending on the total cable

length. For details, refer to Section 3.2.2

(3) Use the same transmission speed for all of the master station and slave

stations. If the setting for even one of the stations is different, data link cannot function properly.

(4) To check whether the same transmission speed is set for all of the master

station and slave stations, obtain the transmission speed settings in the loop test by GX Works2. (Refer to Section 15.4.2)

7 PARAMETER SETTINGS

POINT

(1) The network parameters other than operation setting, station No., mode and

transmission speed are also valid when the programmable controller CPU is switched from STOP to RUN.

(2) When changing the parameters and settings of the master station or slave

station, stop the data link at the master station and then make the changes.

(3) When changing the parameters and settings of slave stations, change the

parameters of the master station according to the slave station change.

(4) For the automatic refresh parameter setting, set the start device only.

Devices are automatically assigned up to the last station number including reserved stations and occupied stations. In the following system configuration example, total of remote I/O points is 96, the total of remote register points is 12, the total of Ver.2 compatible remote I/O points is 1184, and the total of Ver.2 compatible remote register points is 176. Therefore, if refresh device of remote input (RX) is set to "X1000", that of remote register (RWr) is set to "W0", that of Ver.2 compatible remote input (RX) is set to "X1500", and that of Ver.2 compatible remote register (RWr) is set to "W1000", the end devices will be "X105F", "WB", "X199F" and "W10AF" respectively. For link points of each station, refer to Section 3.2 (1).

(5) When setting X, Y, B, W, SB and SW as refresh devices, make setting so that

they do not overlap with the device numbers used on the other networks, etc.

(6) When setting X and Y as refresh devices, set I/O numbers higher than the I/O

numbers used for I/O modules and intelligent function modules.
