1. Outline

1.1 Product Outline

The CC-Link/LT master block FX2N-64CL-M can be connected to the FX Series PLC. The CC-Link/LT system can be constructed with an FX Series PLC as the master station.

1.2 Features

The FX2N-64CL-M has the following features:

1) Reduced wiring time The adoption of flat cabling for CC-Link/LT and special connector allow for reduced wiring

times.

2) Simplified programs Link devices within CC-Link/LT are assigned to X/Y devices in the PLC, therefore, programs

can be prepared without recognizing the network.

3) High speed refresh High speed refresh (128 points/0.3 ms) is realized (as and when the transmission speed is

2.5 Mbps, 16-point mode is selected and eight stations are connected to the network).

4) Slave station disconnection function Even if some units are down due to an abnormality, communication with the remaining

functional units is not affected. However, if the trunk line cable is broken, data link is disabled for all stations.

5) Automatic return function When a unit that was disconnected due to an abnormality is restored to it’s normal status,

the unit will return to the data link automatically and continue data transfer.

6) Data link stop/re-start While data link is being executed, the user can stop and start the link again.

7) Remote station type information storage In the CONFIG mode, the number of points occupied by remote stations, I/O types, etc. is

detected, and stored within the EEPROM.

8) Mode selection The ONLINE, CONFIG and TEST modes are available. ONLINE mode : Executes the data link for the CC-Link/LT system.

Select the ONLINE mode usually.

CONFIG mode: Allows automatic assignment of the I/O No.

When remote stations are planned to be added in the future, reserved stations can be specified and detailed remote station information can be edited. After constructing the CC-Link/LT system, make sure to execute the CONFIG mode once to assign the I/O No.

TEST mode : Executes self-diagnosis to judge whether the FX

-64CL-M itself is in the master station. If the data link cannot be executed normally, the self-diagnosis function analyses the FX

-64CL-M itself.

4. System Configuration

This section explains the CC-Link/LT system configuration.

DESIGN PRECAUTIONS

When a remote I/O unit fails, outputs may randomly turn ON or OFF, therefore, build an external monitoring circuit that will protect from any input signals that could cause a serious accident.

DESIGN PRECAUTIONS

• Do not bind control cables and flat cables dedicated to CC-Link/LT together with power cables. Keep control cables and flat cables dedicated to CC-Link/LT away from major circuits and power cables by 100 mm (3.93") or more. It may cause a malfunction due to noise interference.

• Use the FX

-64CL-M in anenvironment status that any force is not directly applied on connectors for CC-Link/LT interface and flat cables dedicated to CC-Link/LT. If any force is applied, wire breakage and failure may occur.

4.1 Total configuration

This paragraph describes the system configuration and cautions for CC-Link/LT.

• Connect the master station, power adapter and remote stations using the flat cables dedicated to CC-Link/LT and the connectors for dedicated flat cables.

• The connection order of remote stations has no relevance to the station No. Even if the station No. of remote stations is not consecutive, no error will occur in the data link.

• In the CC-Link/LT system, terminating resistors should be connected to both ends of the trunk line. Connect the terminating resistor on the FX

-64CL-M side to a position within 200 mm

(7.87") from the FX

-64CL-M.

• Make sure to lay out the master block on one side of the trunk line.

• Up to 64 remote stations can be connected to one FX

-64CL-M as far as the condition

shown in the table below are satisfied.

• Equipment for CC-Link cannot be connected to the CC-Link/LT system. On the contrary, equipment for CC-Link/LT cannot be connected to the CC-Link system.

• Refer to the respective instruction manuals when installing the power adapter or remote I/O units.

• Refer to the homepage of the CC-Link Partner Association (CLPA) "http://www.cc-link.org/" for details concerning flat cabling, terminating resistors and connector for CC-Link/LT.

4.2 PLC connection

This paragraph explains which PLC series are connectable with the FX2N-64CL-M and cautions on the number of connectable FX

-64CL-M.

4.2.1 Applicable PLC and number of connectable FX

-64CL-M

• Connect the FX

-64CL-M to the right side of the PLC using an extension cable.

• The number of occupied I/O points is "8 (either input or output) points + Number of connected remote I/O points". The total number of I/O points including extended points must not exceed 128 points for the FX

Series or 256 points for the FX2N or FX

2NC

Series.

• The FX

-64CL-M consumes 190 mA at 5V DC. The total current consumption at 5V for special blocks connected to the PLC must not exceed the 5 V power capacity of the main and extension units. When connecting to the FX

Series PLC, a maximum of two FX2N-64CL-M can be

connected to each of the main and extension units.

4.3 Power adapters installation concept

At least one power adapter is required per CC-Link/LT system. When constructing a system using only one power adapter, the following three conditions should be satisfied:

1) Total current consumption of remote I/O units, I/O equipment and master unit receiving power from power adapter ≤ 5 A

2) To operate the system in a stable environment, the voltage drop should be equivalent to or less than 3.6V.

3) Because the minimum operating voltage of each remote I/O unit connected to the power adapter is 20.4 V, therefore, Supply voltage to power adapter - Voltage drop ≥ 20.4 V

If the total current consumption or voltage drop is large, the power adapter position should be changed or additional power adapters should be installed. For further details, refer to the "CL1PAD1 (Power Adapter) USER'S MANUAL (Detailed Volume)" offered separately.

4.4 Power adapter installation condition

For further details on power adapter installation conditions, refer to the "CL1PAD1 (Power Adapter) USER'S MANUAL (Detailed Volume)" offered separately. The conditions for installing power adapters to the CC-Link/LT system depend on connected equipment and wiring length.

6.2.2 Wiring check

Confirm the wiring between remote I/O units and external equipment.

Example of wiring check

The figure below shows an example in which the head I/O No. in the FX

-64CL-M is X020/

Y020 and 4-point mode is selected.

Operating procedure

1) Connect the FX

-64CL-M, power adapter and remote I/O units using the dedicated cables. Set the transmission speed, point mode, station No., etc. using the DIP switches in the FX

-64CL-M and remote I/O units.

At this time, select the CONFIG mode in the FX

-64CL-M (by setting bit 6 ON and setting

bit 7 OFF).

2) Supply power to the power adapter before the PLC unit.

3) When the acquisition of remote I/O unit information is completed in the CONFIG mode (that is, when b4 of the BFM #28 (1Ch) turns ON), turn the power OFF.

4) Set the FX

-64CL-M to ONLINE mode (by setting bit 6 OFF and bit 7 OFF). Supply power

to the power adapter before the FX

-64CL-M. Then, execute step a) or b) below.

a) Checking the wiring between the input unit and external equipment

- Turn ON the switch corresponding to "X020" of the external equipment connected to the input unit with station No. is 1.

- Monitor X020 from peripheral equipment.

- If X020 is ON, connection between the input unit and external equipment is normal.

b) Check the wiring between the output unit and external equipment

- Turn Y020 ON/OFF from peripheral equipment using the forced ON/OFF operation.

- If the connection between the output unit and external equipment is normal, a lamp corresponding to "Y020" in the external equipment will light.

Various Modes 7

7-1

7. Various Modes

The FX2N-64CL-M has ONLINE, CONFIG and TEST modes. Each mode can be selected using the appropriate DIP switch. (Turn OFF the power to the PLC before setting the DIP switches.)

7.1 ONLINE mode (DIP switch bit 6 = OFF, bit 7 = OFF)

In ONLINE mode, the FX2N-64CL-M will execute the data link in the CC-Link/LT system. Select this mode for normal use.

7.2 CONFIG mode (DIP switch bit 6 = ON, bit 7 = OFF)

In CONFIG mode, the FX2N-64CL-M assigns the station No. and I/O Nos. for remote stations. The FX

-64CL-M acquires the information (I/O type and number of points) on the connected remote stations, then stores it to the buffer memory [BFM #32 (20h) to #95 (5Fh)] and built-in memory (EEPROM). After constructing the CC-Link/LT system, execute the CONFIG mode to automatically assign the I/O Nos. (After constructing the CC-Link/LT system, assign the I/O Nos. by executing the CONFIG mode.) If remote stations are to be extended in the future, the I/O Nos. can be assigned while skipping some I/O Nos. For the details of assignment of the I/O Nos., refer to "8. Assignment of I/O Nos."

7.3 TEST mode (self-loop-back test) (DIP switch bit 6 = OFF, bit 7 = ON)

In TEST mode (for the self-loop-back test), the FX2N-64CL-M checks whether it is fully functional by receiving data sent by itself. In this test, it is not necessary to connect remote stations. (Connect the FX

-64CL-M to the power adapter, then turn ON the communication power.)

For details on the self-loop-back test, refer to "12.4 Self-loop-back test".

• When the FX

-64CL-M is set to the TEST mode while it is connected to a FX1N Series PLC, the PLC is stopped. (The self-loop-back test will be executed normally, and the test result will be indicated by the status indicator LEDs.)

Assignment of I/O Nos. 8

8-1

8. Assignment of I/O Nos.

The FX2N-64CL-M assigns I/O information for remote I/O units to devices X (input) and Y (output) in the PLC. The I/O Nos. are assigned in CONFIG mode. At this time, the I/O Nos. are assigned in octal serial Nos. following the I/O No. occupied by the PLC while eight points are handled as one block. (For further details, refer to "8.2 Example of I/O No. assignment") For a station No. to which a remote I/O unit will be connected to in the future, the I/O No. can be secured by "specifying it as a reserved station" and "editing the detailed remote station information on it".

8.1 Relationship between I/O No. and point mode

The I/O No. is equivalent between the 4-point mode and 16-point mode, but the station No. of each remote station is different between 4-point mode and 16-point mode. When using remote I/O units of more than 4 I/O points, more I/O points can be used if the 16point mode is selected due to the restriction in the number of connected stations (64 stations maximum).

Example:When sixty-three CL1XY2-DT1D5S units (cable type remote unit having 1 input point

and 1 output point) (station No.: 1 to 63) and one CL2X8-D1B2 unit (terminal block type remote I/O unit having 8 input points) are to be connected to the FX

-16MR, a system can be constructed in the 16-point mode, but cannot be constructed in the 4point mode due to the CL2X8-D1B2 unit occupying two stations and the number of remote stations exceeds 64.

However, if the number of stations is equivalent, the link scan time is longer in the 16-point mode than in the 4-point mode. (For further details of the link scan, refer to "9. Data Link Processing Time".)

1) When connecting all remote I/O units and assigning their I/O Nos., refer to "8.3 Automatic I/O No. assignment".

2) When assigning the I/O Nos. without connecting remote I/O units and preparing a sequence program or connecting additional remote I/O units in the future, refer to "8.3 Automatic I/O No. assignment" and "8.4 Specification of reserved station" and "8.5 Edition of detailed remote station information".

• In CONFIG mode, the FX

-64CL-M does not occupy I/O points for remote stations. (It occupies only 8 points as a special block.) I/O extension blocks/units of the PLC connected after the FX

-64CL-M do not operate.

FX2N-64CL-M CC-Link/LT Master Block Assignment of I/O Nos. 8

8-2

8.2 Example of I/O No. assignment

This paragraph describes I/O No. assignment in the configuration example shown below.

When the FX

-64CL-M is set to the CONFIG mode and the PLC is powered ON, the FX2N64CL-M checks for connected remote stations, and assigns the I/O No. to each remote station. Though the I/O No. is equivalent between the 4-point mode and 16-point mode, the station No. of each remote station is different between the 4-point mode and 16-point mode. In the configuration example above, the link scan time is longer in the 16-point mode than in the 4-point mode. (For the details of the link scan, refer to "9. Data Link Processing Time".)

*1 With regard to X and Y, 8 points are occupied as 1 block. As a result, if the number of I/O

points occupied by a station is a number which cannot be divided by "8", unused Nos. are generated. In the configuration example above, the I/O Nos. are assigned as shown below.

Station No.

Station No.1 Station No.1 4 input points X040 to X043 --

8.3 Automatic I/O No. assignment

The I/O Nos. can be assigned automatically in the CONFIG mode. Parameter settings and sequence programs are not necessary for this assignment.

8.3.1 Automatic I/O No. assignment procedure

Execute the steps 1) to 3) below to automatically assign the I/O Nos.

1) Connect each remote I/O unit to the FX

-64CL-M. In the FX2N-64CL-M, set bit 6 of the DIP switch to ON, and set bit 7 (to select the CONFIG mode) to OFF. Power up, first, the power adapter, then, the PLC. The FX

-64CL-M acquires the information (I/O type and number of points) on connected remote stations, and stores it to the buffer memory [BFM #32 (20h) to #95 (5Fh)] and builtin memory (EEPROM).

2) Confirm that the contents of the buffer memory [BFM #32 (20h) to #95 (5Fh)] are consistent with the actual system configuration.

3) Set bit 6 of the DIP switch in the FX

-64CL-M to OFF. Reset the power to the PLC.

The FX

-64CL-M reads the information on connected remote stations from the built-in

memory (EEPROM), and assigns the I/O No.

8.4 Specification of reserved station

The FX2N-64CL-M assigns the I/O No. in the CONFIG mode. If remote stations will be added in the future, temporary I/O Nos. can be assigned (specification of reserved stations). By this function, even if remote stations are added, it is not necessary to change the I/O Nos. assigned to other remote stations and extension blocks/units connected to the PLC. If remote stations are connected in places for reserved station, the connected remote stations can operate with the existing setting, but errors such as wire breakage cannot be detected. After connecting remote additional stations, execute automatic I/O No. assignment in the CONFIG mode again. The system will update the detailed remote station information, and the new remote stations will be able to be used normally (errors will be detected).

8-4

8.4.1 Reserved station setting method

Set reserved stations using the steps 1) to 4) below.

1) Set the FX

-64CL-M to the CONFIG Mode (by setting bit 6 of the DIP switch to ON and

setting bit 7 to OFF). Power up the FX

-64CL-M.

(The FX

8.5 Editing the detailed remote station information

After assigning the I/O Nos. in the CONFIG mode, the I/O No. assignment in each station No. can be edited. With this function, the number of I/O points can be changed, and the I/O Nos. can be assigned to unconnected station Nos. for future use. If remote stations are added in the future, it is not necessary to change the I/O Nos. in other remote stations and extension blocks/units connected to the PLC. If a remote station is not connected to an edited station No., errors such as wire breakage error will occur. If a remote station is connected to an edited station No. the remote station will operate with the existing setting.

8.5.1 How to edit detailed remote station information

Edit the detailed remote station information using the steps 1) to 4) below.

1) Set the FX

-64CL-M to the CONFIG Mode (by setting bit 6 of the DIP switch to ON and

setting bit 7 to OFF). Set the power of the FX

-64CL-M to ON.

(The FX

-64CL-M will assign the I/O Nos.)

2) Write the information (station type and number of I/O points) for the station to be added in the detailed remote station information buffers [BFM #32 (20h) to #95 (5Fh)]. Set the reserved station flag (bit 15) to OFF in the appropriate BFM. (If the bit for reserved station is set to ON, the station is regarded as a reserved one, and errors such as wire breakage error cannot be detected.)

3) To the detailed remote station information on every remote station to be edited, write the information on the remote station. Then, give the instruction for write to the EEPROM [by setting b4 of the BFM #27 (1Bh) from OFF to ON].

4) After editing the remote station information, confirm that write to the EEPROM is completed by checking b4 of the BFM #28 (1Ch). Then, set the power of the FX

-64CL-M to ON using the normal procedure (by setting bit 6 of the DIP switch to OFF), and confirm that the detailed remote station information [BFM #32 (20h) to BFM #95 (5Fh)] is updated.

9. Data Link Processing Time

This section explains the link scan time and transmission delay time.

9.1 Link scan time

This paragraph explains the link scan time for the CC-Link/LT network.

9.1.1 Link scan time calculation formula

Link scan time = a + ( b × N ) × c [µs]

a: Constant (depends on the transmission speed)

b: Constant (depends on the transmission speed and point mode)

c: Constant (depends on the transmission speed)

N: Final station No.

As shown in the formula above, if the number of stations is held constant, the link scan time is shorter in the 4-point mode than in the 16-point mode.

9.1.2 Transmission delay time

The transmission delay time (the time until data is received) (including the time for communication between the main unit and FX

-64CL-M) can be calculated by the following

formula.

1) Master station ← Remote station (input) Time until a device (X) in the main unit turns ON or OFF after a signal is input to the remote

station

Calculation formula

2 + (2 - n)*1 × LS + Remote station input response time [ms] SM: Scan time of master station PLC LS: Link scan time n: SM/LS (whose decimals are omitted) *1: 0 if the value "2-n" is 0 or less

Example:

The scan time of the master station PLC is 5 ms, the link scan time is 1.2 ms, and the input response time of the remote I/O station is 1.5 ms

2 + (2 - n)*1 × LS + Remote station input response time [ms]

= 5

2 + (2 - 4)

1.2 + 1.5 [n = 4 (5/1.2 = 4.16..., then decimals are omitted)]

= 11.5 [ms]

2) Master station → Remote station (output) Time until an output in the remote station turns ON or OFF after a device (Y) in the main

unit is set to ON or OFF

Calculation formula

SM + LS × 2 + Remote station output response time [ms]

SM: Scan time of master station PLC LS: Link scan time

Example:

The scan time of the master station PLC is 5 ms, the link scan time is 1.2 ms, and the output response time of the remote I/O station is 0.5 ms

SM + LS × 2 + Remote station output response time [ms] = 5 + 1.2 × 2 + 0.5 = 7.9 [ms]

Assignment of Buffer Memory 10

10-1

10. Assignment of Buffer Memory

Data transfer between the PLC main unit and FX2N-64CL-M is executed by a program in the PLC. Use the FROM instruction to read data saved in the FX

-64CL-M to the main unit.

The FROM instruction reads the data saved in the buffer memory (BFM) in the FX

-64CL-M to devices (such as D and M) in the main unit. Use the TO instruction to write data from the main unit to the FX

-64CL-M. The TO instruction writes data from devices (such as D and M) in the main unit to the buffer memory (BFM) in the FX

-64CL-M.

10.2 Details of buffer memory

10.2.1 Remote station connection information [BFM #0 (0h) to #3 (3h)]

The connection status of remote stations connected in the system are stored in BFM #0 to BFM #3 (bits for connected stations are ON). Once a bit for a remote station turns ON, it remains ON even if communication error occurs in the remote station due to wire breakage, etc (this information cannot be used to confirm the communication).

The station No. of each remote station is assigned to each bit of the buffer memory [BFM #0 (0h) to #3 (3h)]. Connection/disconnection is indicated by the 0 (OFF)/1 (ON) status of each bit.

0 (OFF): Corresponding remote station is not connected. 1 (ON): Corresponding remote station is connected.

10.2.2 Link error station information [BFM #4 (4h) to #7 (7h)]

The data link status of remote stations is stored here (bits for stations having link error are ON). Among remote stations whose I/O Nos. are written in the EEPROM (e.g. remote stations connected in the CONFIG mode or remote stations whose information is written by editing of the detailed remote station information), remote stations with which communication is disabled are regarded as data link error stations, and corresponding bits are set to ON. When communication with a remote station is restored, the ON status is cleared. However, unused stations and reserved stations are not regarded as data link error stations. If a remote station whose parameters are not written in the EEPROM gives a response, it is regarded as control disability (due to I/O non-assignment), and regarded as a data link error. Inconsistency of the station type is not checked (even if the station type is inconsistent, it is not regarded as data link error).

The station No. of each remote station is assigned to each bit of the buffer memory [BFM #4 (4h) to #7 (7h)]. Normal status/data link error is indicated by the 0 (OFF)/1 (ON) status of each bit.

0 (OFF): The station is normal. 1 (ON): Data link error has occurred in the station.

Handling in the CONFIG mode

In the CONFIG mode, if the detailed remote station information [BFM #32 (20h) to #95 (5Fh)] is edited, and if the detailed remote station information is inconsistent with remote stations actually connected at the time of power ON as a result of the editing, there will be a data link error. While the detailed remote station information is being edited, the consistency with actually connected stations is checked. If the power is set to ON while all remote stations are unconnected or if remote stations are disconnected after the power was set to ON, data link error is not detected, as far as the detailed remote station information is not edited. (For the details on editing the detailed remote station information, refer to "8.5 Editing the detailed remote station information".)

11. Program Example

This section describes a program in the PLC for the configuration shown in "11.2 System configuration". In this example, the I/O Nos. are assigned automatically in the CONFIG mode. The specification as reserved station and the detailed remote station information are not changed. Parameter settings and programs for assigning the I/O Nos. are not necessary.

DESIGN PRECAUTIONS

• When a remote I/O unit fails, outputs may randomly become ON or OFF, therefore an

external monitoring circuit that will monitor any input signals that could cause a serious accident is necessary.

DESIGN PRECAUTIONS

• Do not bind control cables and flat cables dedicated to CC-Link/LT together with power

cables. Keep control cables and flat cables dedicated to CC-Link/LT away from major circuits and power cables by 100 mm (3.93") or more. There may be malfunction due to noise interference.

• Install the FX

-64CL-M in such away that no force is applied to connectors on the CC-Link/LT interface and the flat cables dedicated to CC-Link/LT. If any force is applied, wire breakage and failure may occur.

INSTALLATION PRECAUTIONS

• Use the FX2N-64CL-M in an environment with the general specifications described in this manual. If the FX

-64CL-M is used in any other environment, electrical shock, fire, malfunction,

product damage or product deterioration may occur.

• Do not touch the conductive area of the FX

-64CL-M.

If the conductive area is touched directly, the FX

-64CL-M may malfunction or fail.

• Shut down all power supplies before attaching/removing the FX

-64CL-M to/from the panel. If the power is not disconnected from all sources, the FX

-64CL-M may fail or

malfunction.

• Securely fix the FX

• Install the FX

-64CL-M on a flat surface. If the installation surface is not flat, an excessive force may be applied on the PCBs, leading to nonconformity.

11-2

WIRING PRECAUTIONS

• Make sure to shut down all power supplies before starting the installation or wiring work. If the power is not disconnected from all sources an electric shock or serious product damage may occur.

WIRING PRECAUTIONS

• Correctly wire the master block while confirming the rated voltage and terminal arrangement of the FX

-64CL-M. If a power supply different from the rating is connected or wiring is performed incorrectly, fire or failure may be caused.

• Correctly wire the master block while confirming the rated voltage and terminal arrangement of the FX

-64CL-M. If a power supply different from the rating is connected or wiring is performed incorrectly, fire or failure may be caused.

• Pay attention that foreign objects such as cuttings or wiring chips do not enter the FX

64CL-M. It may cause fire, product failure or malfunction.

STARTING AND MAINTENANCE PRECAUTIONS

• Do not touch the terminals when the power is ON. It may cause an electric shock or malfunction.

STARTING AND MAINTENANCE PRECAUTIONS

• Do not disassemble or modify the FX2N-64CL-M. Doing so may cause failure, malfunction, injury, or fire.

• The case of the FX

12.5 Prevention of erroneous inputs to and outputs from remote I/O unit

In order to prevent erroneous inputs to and outputs from remote I/O units, design the system under consideration of the contents described below.

1) When setting the power to ON or OFF Set the power of remote I/O units to ON (the power of the power adapter) first, then start the

data link. Stop the data link first, then set the power of remote I/O units to OFF (the power of the power adapter).

2) When the power is interrupted instantaneously in a remote I/O unit When the power (24V DC) supplied to a remote I/O unit is interrupted instantaneously,

erroneous inputs may occur.

a) Cause of erroneous inputs due to instantaneous power interruption

The hardware of a remote I/O unit converts the unit power (24 VDC) into 5V DC inside, then uses it. If instantaneous power interruption occurs in a remote I/O unit,

(Time until 5V DC inside remote I/O unit turns OFF)

> (Response time for "ON → OFF" of input unit)

As a result, if refresh is executed in the period shown in (A) below, erroneous inputs occur. (Erroneous inputs may occur especially while the input response time is set to highspeed input type.)
