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

[DESIGN PRECAUTIONS]

WARNING

 For details on the operating status of each station when a communication problem occurs in the

data link, refer to Section 6.5 of this manual.

 If a cable dedicated to the CC-Link is disconnected, this may destabilize the line, and a data link

communication error may occur in multiple stations. Make sure to create an interlock circuit in the sequence program so that the system will operate safely even if the above error occurs. Failure to do so may result in a serous accident due to faulty output or malfunctions.

 When performing the control of the personal computer in operation (changing data), configure

an interlock circuit in a user program so the safety of the overall system is always maintained. When performing other controls of the personal computer in operation (changing program and operation status (status control)), read this manual carefully and confirm if the overall safety is maintained. Especially, when this control is performed to a remote personal computer from an external device, problems that have occurred on the personal computer side may not be able to immediately be handled if there is a data communication error. Define a troubleshooting agreement between external devices and the personal computer for data communication error occurrences, as well as construct an interlock circuit in the user program.

 Do not write any data from the user program into the "system area" of the board buffer memory.

Writing data into the "system area" may cause a CC-Link system malfunction.

 A failure in the board may cause remote I/O not to turn on or off correctly.

For critical I/O signals that may cause a serious accident, establish a circuit to externally monitor them.

[DESIGN PRECAUTIONS]

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 100mm (3.94 in.) or more from each other. Not doing so could result in noise that may cause malfunction.

[INSTALLATION PRECAUTIONS]

CAUTION

 Use the board in an environment that meets the general specifications contained in this user's

manual. Using this board in an environment outside the range of the general specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the product.

 Do not directly touch the conductive area or electronic components of the board.

Doing so may cause malfunction or failure in the board.

 Fix the board by tighten the board-fixing screws within the specified torque range.

Under tightening may cause drop of the component or wire, short circuit, or malfunction. Over tightening may damage the screw and/or module, resulting in drop, short circuit, or malfunction. For the tightening torque of the board fixing screws, refer to the manual supplied with the personal computer.

 Always make sure to touch the grounded metal to discharge the electricity charged in the body,

etc., before touching the board. Failure to do so may cause a failure or malfunctions of the board.

 Be sure to shut off all phases of the external power supply used by the system before installing

or removing the board. If all power is not turned off, not doing so may cause damage to the product.

 Install the board to a personal computer which is compliant with PCI standard or PCI Express

standard (Section 2.3). Failure to do so may cause a failure or malfunction.

 Securely mount the board to the PCI slot of the mounting device.

(5) System down prevention (Slave station disconnect function)

Even if a module system fails because of power failure or power off, it will not affect the communication with other normal modules since the system employs the bus connection method. Also, for a module using a 2-piece terminal block, the module can be replaced during data link. (Replace the module after turning its power off. Also check that the switch setting on the replaced module is same as the one set on the module before replacement.) However, if the cable is disconnected, the data link to all stations is disabled.

(15) Backward compatibility

By setting the Remote net ver.1 mode, the user program of the CC-Link Ver.1 board can be used on the CC-Link Ver.2 board. Select the remote net ver.1 mode when the cyclic points increasing is not required or when the CC-Link Ver.2 board is used as substitute for the CC-Link Ver.1 board.

(16) Cyclic points increase function

When the Remote net ver.2 mode or Remote net additional mode is selected, the number of cyclic points can be increased up to 8192 points for RX/RY and up to 2048 words for RWr/RWw per network by the expanded cyclic setting (single, double, quadruple or octuple). Also, it can be increased up to 224 points for RX/RY and up to 32 words for RWr/RWw per station. (Refer to Section 4.4.7)

(17) Remote I/O station points setting

I/O points are set for remote I/O stations. Since only the points used in remote input RX and remote output RY need to be set for remote I/O stations, the reserved points for the remote I/O stations can be reduced. This enables the minimum remote device allocation in the CC-Link system. (Refer to Section 4.4.6)

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

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

[Cause for erroneous inputs due to a momentary power failure]

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

MELSEC

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 situation occurs: (Time for the 5 V DC power in the remote I/O module to turn off)

> (Response time for input module on

off) Thus, an erroneous input occurs when a refresh is performed within the time indicated by 1) in the figure below.

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 changes from on to off.

REMARK

When supplying power from a single power source to multiple remote I/O modules, select the proper type of cable and perform wiring by considering the 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.

(4) Access to slave station No.64

When the CC-Link Ver.2 board is used, transient transmission to slave station No.64 is not allowed.

REMARK

(1) Access to slave station No.64 is not possible even from GX Developer, GX

Works2 or GOT on any other station.

(2) Cyclic transmission can be normally performed with slave station No.64.

Item Description Reference section

By assigning modules that will be connected in the future as reserved stations, these will not be treated as data link faulty stations. The reserved stations can also be set as 0 points. If any of the connected modules is designated as a reserved station, it cannot perform data link.

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

Checks for duplicate modules having the same station number in the system.

Allows access to any CPU of a multiple CPU system via a CC-Link Ver.2 board.

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.

Allows the number of cyclic points per module to be increased from 128 points for RX/RY and 16 points for RWr/RWw in the ver.1 mode to up to 896 points for RX/RY and 128 points for RWr/RWw in the ver.2 mode.

(3) Notes on using the standby master function

(a) Only one standby master station is allowed in a single data link system.

(b) The total number of stations can be no more than 64, including the standby

master station. The number of stations that can be occupied by the standby master station is one or four.

station exists. If it is specified, station number 64 cannot communicate normally.

(d) If any abnormality is detected at the master station in the initial status (before

parameter communication starts), the switch to the standby master station will not be executed.

(e) When the master station becomes faulty, the data link control will

automatically be transferred to the standby master station, but the cyclic transmission data will not be transferred. Instructs to perform the switching direction (SB0001 is ON) with a user program. After switching the data link startup (SB0043) from the standby master station to the master station is completed, the information before the detection of abnormality at the master station will be output to each station. Note that, a transient transmission to the master station cannot be performed until switching the data link startup (SB0043) from the standby master station to the master station is completed. (If the transient transmission is performed before the switching is completed, a timeout error will occur in the request source.) Perform transient transmission to the master station after instructing to perform the switching direction of the cyclic transmission data with a user program.

(f) The master station duplex function is not available.

The control is switched from the standby master station to the master station only once. Therefore, if the standby master station goes down after the control has been switched to the standby master station due to master station failure, the CC-Link system will stop the data link. (The control will not be switched even if the master station functions properly.)

(g) When the master station goes down and the data link control right is

switched to the standby master station, the standby master station number is identified an error number (Corresponding bits in SB0080 or SW0080 to SW0083 turn ON.) The station number of the standby master station is changed to 0 from the station number set by the parameter because there is no standby master station. The data linking is successfully performed. Specifying a standby master station as an error invalid station prevents this kind of error detection.

(h) When the standby master station is controlling the data link, parameters

cannot be updated.

4.3.5 Monitoring the operation of the software (operating system, driver) inside the hardware (Driver WDT function)

Driver WDT function monitors the operation of the software (operating system, driver) inside the hardware by the timer function on CC-Link Ver.2 board. When the driver cannot reset the timer of the board within the specified driver WDT monitoring time, CC-Link Ver.2 board detects driver WDT error. Driver WDT function detects driver operation delay due to the access error from the driver to CC-Link Ver.2 board or system high load.

(1) Driver WDT settings

For the setting method, refer to section 8.2.5.

REMARK

The driver WDT function is set to invalid as a default.

(2) When the driver WDT error has occurred

The following shows the operation when driver WDT error has occurred.

1) CC-Link Ver.2 board and the driver stop link refresh and communication and are disconnected from the network in order to avoid an erroneous output. A CPU stop error occurs when checking the CC-Link Ver.2 board from other station on which the driver WDT error has occurred.

2) RUN LED flicks and SD LED turns ON on the CC-Link Ver.2 board.

3) "-28158 (9202H) Driver WDT error" occurs when accessing CC-Link Ver.2

board from the application program in which the CC-Link Ver.2 utility and MELSEC data link library function are used.

POINT

(1) When the multiple applications in which MELSEC data link library is used are

executed, driver WDT error is returned to all the programs. However, only the CC-Link Ver.2 board in which the driver WDT error has occurred is recognized as an error station on the network.

4.3.6 Station-based block data assurance function

The block data assurance per station setting refers to a prevention of separating cyclic data to new data and old data. Cyclic data may be separated between new and old data depending on the timing of the link refresh. This function prevents read/write data per slave station from being separated between new and old data. Only by setting parameters in the CC-Link Ver.2 utility, it can be prevent separation of the data.

POINT

When using block data assurance per station setting, SW1DNC-CCBD2-B Version

1.17T or later and CC-Link Ver.2 board ROM version 2B or later are required.

(1) The target device of the block data assurance per station setting

The target device of the block data assurance per station setting is link device (RX/RY/RWr/RWw). When the block data assurance per station is enabled, the link refresh is executed between the CC-Link Ver.2 board driver buffer (RX buffer/RY buffer/RWr buffer/RWw buffer) and the area assigned to each station in the link device. The area of the link device assigned to each station is the respective slave station and data will be assured.

(2) Access method for link devices

The access method varies from the user program to the link device depending on the setting of block data assurance per station.

(a) In the case of block data assurance per station is disabled

Accessing (reading/writing) the data from the user program is directly carried out with respect to the link device of CC-Link Ver.2 board. To prevent separation of the data, it is necessary to implement the data separation prevention function in the user program. This explains the case where personal computer transmits the data (RY0) to programmable controller (X0) cyclically.

1) The link device RY0 of the CC-Link Ver.2 board on the sending side (personal computer) becomes ON when the user program turns ON the RY0.

2) By a link scan, the link device data (RY0) is stored in a link device (RX0) of CC-Link system master/local module on the receiving side.

3) By a link refresh, the data (RX0) is stored in a device (X0) of the CPU module.

(b) In the case of block data assurance per station is enabled

The data is accessed (read/write) from the user program with respect to the CC-Link Ver.2 board driver buffer, and the data of CC-Link Ver.2 board driver buffer and CC-Link Ver.2 board link device will be updated by a link refresh. When block data assurance per station setting is enabled, usually the link refresh will be enabled. It is possible to prevent the cyclic data separation only by setting the parameter without implementing the data separation prevention function in the user program. This explains the case where personal computer transmits the data (RY0) to programmable controller (X0) cyclically.

1) The RY buffer 0 of the CC-Link Ver.2 board driver buffer on the sending side (personal computer) becomes ON when the user program turns ON the RY0.

2) By a link refresh, the RY buffer 0 of the CC-Link Ver.2 board driver buffer is stored in a link device (RY0) of the CC-Link Ver.2 board.

3) By a link scan, the link device data (RY0) is stored in a link device (RX0) of CC-Link system master/local module on the receiving side.

4) By a link refresh, the data (RX0) is stored in a device (X0) of the CPU module.

(3) Link refresh

The link refresh is executed between the link device and the CC-Link Ver.2 board driver buffer. In order to execute the link refresh, set the block data assurance per station setting and the link refresh cycle at <<Parameter settings>> ("Other settings" screen) in the CC-Link Ver.2 utility. Refer to Section 8.2.5 (2). Link refresh time is shown on "Board information" screen ("Board detail information" screen) in the CC-Link Ver.2 utility. Refer to Section 8.2.2 (2). However, link refresh is not executed when the board WDT error, or hardware failure occurred, or data link has stopped.

POINT

(1) If the link refresh cycle is shortened, CPU utilization of the personal computer

may increase and load may become high.

(2) If the link refresh cycle is prolonged, the transmission delay time of the cyclic

data may increase.

(3) Depending on the following causes, the link refresh may not be executed as per

link refresh cycle set in the <<Parameter settings>> ("Other settings" screen).

Performance of a personal computer CPU is low

Too many link refresh points

Too many CC-Link Ver.2 boards has been installed

Overloading due to the other running applications

Overloading due to the other running boards

(4) When the link refresh time checked on the "Board information" screen ("Board

detail information" screen) is longer than the set link refresh cycle, take any of the following actions.

Extend the link refresh cycle

Decrease the remote station points of the whole network

4.4 Useful Functions

This section explains some useful functions for the CC-Link Ver.2 board.

4.4.1 Creating a program that contains modules to be added in the future (reserved station function)

This function prevents any of the remote stations, local stations, intelligent device stations and standby master station that is not actually connected (but that will be connected in the future) from being treated as a "data link faulty station" by the master and local stations. When the master station is in the Remote net ver.2 mode, the number of points for a reserved station can be set to 0.
