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 safety programmable controller detects an error in an external power supply or a failure in programmable controller main module, it turns off all the outputs. Create an external circuit to securely stop the power of hazard by turning off the outputs. Incorrect configuration may result in an accident.

● To inhibit restart without manual operation after safety functions was performed and outputs were turned off, create an interlock program which uses a reset button for restart.

● If CC-Link IE Field Network error has been detected, create a sequence program that turns off the outputs in the program. If the CC-Link IE Field Network is restored with the outputs on, it may suddenly operate and result in an accident.

[Design Precautions]

CAUTION

● Do not bunch the wires of external devices or communication cables together with the main circuit or power lines, or install them close to each other. They should be installed 100 mm (3.94 inch) or more from each other. Not doing so could result in noise that would cause malfunctions.

[Installation Precautions]

CAUTION

● Use a safety programmable controller in the environment that meets the general specifications described in the QSCPU User's Manual (Hardware Design, Maintenance and Inspection). Using this programmable controller in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.

● While pressing the installation lever located at the bottom of module, insert the module fixing tab into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing hole as a supporting point. Incorrect loading of the module can cause a failure or drop. Secure the module to the base unit with screws. Tighten the screw in the specified torque range. If the screws are too loose, it may cause a drop of the screw or module. Overtightening may cause a drop due to the damage of the screw or module.

● Completely turn off the external supply power used in the system before mounting or removing the module. Not doing so could result in damage to the product.

● Do not directly touch the module's conductive parts or electronic components. Doing so may cause malfunctions or a failure.

[Wiring Precautions]

WARNING

● Be sure to shut off all phases of the external supply power used by the system before wiring. Not completely turning off all power could result in electric shock or damage to the product.

● When energizing or operating the module after installation or wiring, be sure to close the attached terminal cover. Not doing so may result in electric shock.

Page 5

[Wiring Precautions]

CAUTION

● Tighten a module fixing screw within the specified torque range. If the module fixing screw is too loose, it may cause a drop of the screw or module. Overtightening the screw may cause a drop due to the damage of the screw or module.

● Be sure there are no foreign substances such as sawdust or wiring debris inside the module. Such debris could cause a fire, failure, or malfunctions.

● The module has an ingress prevention label on its top to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not peel this label during wiring. Before starting system operation, be sure to peel this label because of heat dissipation.

● Be sure to fix the communication cables or power cables by ducts or clamps when connecting them to the module. Failure to do so may cause damage of the module or cables due to a wobble, unintentional shifting, or accidental pull of the cables, or malfunctions due to poor contact of the cable.

● When removing the connected communication cables or power cables, do not pull the cable with grasping the cable part. Pulling the cable connected to a module may result in malfunctions or damage of the module or cable.

● For the cables to be used in CC-Link IE Field Network, use the ones specified by the manufacturer. Otherwise, the performance of CC-Link IE Field Network is not guaranteed. As to the maximum overall cable length and station - to station cable length, follow the specifications described in the MELSEC-QS CC-Link IE Field Network Master/Local Module User's Manual. If not following the specification, the normal data transmission is not guaranteed.

[Startup and Maintenance Precautions]

WARNING

● Turn off all phases of the external supply power used in the system when cleaning the module or retightening the module fixing screws. Not doing so could result in electric shock. Tighten a fixing screw within the specified torque range. If the module fixing screw is too loose, it may cause a drop of the screw or module. Overtightening the screw may cause a drop due to the damage of the screw or module.

[Startup and Maintenance Precautions]

CAUTION

● Do not disassemble or modify the modules. Doing so could cause a failure, malfunctions, injury, or fire. If the product is repaired or remodeled by other than the specified FA centers or us, the warranty is not covered.

● Completely turn off the external supply power used in the system before mounting or removing the module. Not doing so may result in a failure or malfunctions of the module.

● Restrict the mounting/removal of a module, base unit, and terminal block up to 50 times (IEC61131-2 compliant), after the first use of the product. Failure to do so may cause the module to malfunction due to poor contact of connector.

● Before touching the module, always touch grounded metal, etc. to discharge static electricity from human body, etc. Not doing so may result in a failure or malfunctions of the module.

(2) 1Gbps communication speed

1Gbps communication speed allows high-speed communication. Also, the takt time can be reduced due to the

improved performance of communication response.

(3) Use of Ethernet cable

A 1000BASE-T-compliant Ethernet is used for the connection interface. The wiring cost can be reduced because

1000BASE-T-compliant Ethernet cables are commercially available. ( Page 56, Section 5.2)

1000BASE-T

(4) Flexible wiring for system arrangements

The network can be wired into star topology, line topology, and ring topology. ( Page 47, Section 5.1.1)

For star topology, a 1000BASE-T compliant switching hub can be used. ( Page 57, Section 5.2.2)

Wiring is highly flexible because a network can consist of a combination of star and line topologies. For example,

the control panels can be connected through a star topology and the production lines through a line topology.

Safety communication

A master/local module is used to connect a safety programmable controller to CC-Link IE Field Network.

The module is used being mounted on a safety base unit.

The module can be used as the following stations on CC-Link IE Field Network.

• Master station (safety station)

• Local station (safety station)

• Local station (standard station)

Data communication ensuring high safety (safety communication) can be performed.

Data is communicated after a safety connection is established between safety stations on the same network.

( Page 96, Section 8.1)

(a) Safety stations added on CC-Link IE Field Network

Safety programmable controllers and standard programmable controllers can co-exist on the same network. A

network system with high safety can be easily established by adding safety stations on an existing CC-Link IE

Field Network. ( Page 47, Section 5.1.1)

The master/local module has acquired certification of the highest safety level (SIL3 of IEC 61508, Category 4 of EN 654-1, and Category 4 performance level

"e" of EN ISO 13849-1) applicable to programmable controllers.

Page 25

CHAPTER 1 CC-Link IE FIELD NETWORK

(2) High-speed periodic communication (cyclic transmission)

Since transmission delay time is short, delay caused by the network does not need to be considered (if the link

scan time of each master/local module is shorter than the scan time of the safety CPU module).

Command

High speed

Master/local modules can perform cyclic transmissions in combination with the following functions:

( Page 35, Section 3.3)

• Auto transfer of data between the link devices in the master/local module and the devices in the safety CPU module

station)

(1) Safety communication function

Function Description Reference

Communication with safety stations

Error log registration function

Safety station interlock function

Communication starts among safety stations on the same network

after safety connections are established.

Information on errors occurred in safety stations and errors

occurred in communications among safety stations are transferred

to the safety CPU module and registered as error logs.

If an error occurs in safety communication, this function cuts off the

safety communication and prevents automatic resumption of the

communication.

(2) Cyclic transmission

Function Description Reference

Communication

Communication by

RWr and RWw

Link refresh

The master station (safety station) communicates I/O data in units

of bits with other stations.

The master station (safety station) communicates I/O data in units

of words with other stations.

Transfer between the link device of the master/local module and the

device of the safety CPU module is performed automatically.

This mode is selected for optimizing the performance of cyclic

transmission based on the cyclic transmission and transient

transmission frequency.

The mode can be selected from "Online (Normal mode)" and

"Online (High-speed mode)".

The cyclic data integrity is assured in units of 32 bits or station-

based units.

Link scan is set to asynchronous or synchronous with the sequence

scan of the safety CPU module.

Select whether the input data from another station where the data

link error occurred is cleared or held.

When the safety CPU module mounted with a master/local module

is set to STOP, whether cyclic data output is held or cleared can be

selected.

During debugging and other operations, cyclic transmission is

stopped. (Data reception from the slave station and data

transmission from own stations are stopped.) Also, the stopped

cyclic transmission is restarted.

Transient transmission is not stopped.

By setting the routing parameters (communication path) using GX

Developer in advance, transient transmission can be performed to

stations on different networks through dedicated instructions or GX

Developer. Seamless communication is available with the following

networks.

• Ethernet

• CC-Link IE Controller Network

• MELSECNET/H

• MELSECNET/10

• CC-Link (when using GX Developer)

Only the slave station where an error occurs is disconnected, and

data link continues with the stations that are operating normally.

In a line topology, all stations connected after the faulty station are

disconnected.

When the station disconnected from the network due to a data link

failure recovers, it automatically returns to the network and restarts

data link (for standard communication only).

Only the station where an error occurs is disconnected, and data

link continues with the stations that are operating normally.

All stations after the faulty station are disconnected in line topology.

By using the loopback function with ring topology, data link

continues with the stations that are operating normally.

(a) Network topology

The network can be wired into star topology, line topology, and ring topology.

A network can consist of a combination of star and line topologies, but the ring topology cannot be combined

with star or line topology.

Item Description

The network is configured into a star using a switching hub and Ethernet cables.

Slave stations can be easily added to the network using this topology. (Add slave stations

reconnected. Therefore, an error may momentarily occur in all the stations.)

Data link continues with the stations that are operating normally.

The network is configured into a line by connecting the modules with Ethernet cables, but

without a switching hub. If an error occurs, stations after the faulty station will be

disconnected.

(3) Precautions

(a) Connecting devices to the same network

Do not connect Ethernet devices (e.g. personal computer) other than CC-Link IE Field Network devices to the

switching hub used by CC-Link IE Field Network. Doing so will cause timeout in the master station, resulting in

disconnection of all the stations.

(b) Configuration in which data link cannot be performed (incorrectly configured ring

topology)

Do not wire devices as shown below. Doing so will cause an error in all stations and data link cannot be performed.

• Connecting both PORT1 and PORT2 to the switching hub

(d) Using a switching hub to configure a ring topology

If ring topology is configured by connecting two stations through two of the switching hub's ports, the following

problems may arise:

• If an Ethernet cable is disconnected, loopback cannot be detected.

• If a station is disconnected due to failure or power-off, data link will stop.

Therefore, do not use a switching hub to configure the ring topology.

Switching hub

(e) Offline mode station in ring topology

In the following cases, the master station or the station connected to the offline mode station cannot detect

loopback.

• One of the Ethernet cables connected to the offline mode station is disconnected.

• A station connected to the offline mode station is disconnected.

To detect loopback, set the offline mode station as a reserved station.

When the offline mode station is disconnected, loopback can be detected.

A station during the RESET status and a station with no station number setting operate as an offline mode station does.

(2) Precautions

This section describes wiring precautions.

(a) Handling

• Place the Ethernet cable 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.

• Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from

your hand, dirt or dust is attached to the core, it can increase transmission loss, arising a problem in data

link.

• Check the following:

• Is any Ethernet cable disconnected?

• Is any of the Ethernet cables shorted?

• Are the connectors securely connected?

(b) Broken cable latch

Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.

Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling a cable connected to

the module may damage the module or cable, or result in malfunction due to poor contact.

(d) Connectors without Ethernet cable

Attached connector cover should be placed to prevent foreign matter such as dirt or dust.

(e) Maximum station-to-station distance (maximum cable length)

The maximum station-to-station distance is 100m. However, the distance may be shorter depending on the

operating environment of the cable. For details, contact your cable manufacturer.

(f) Bend radius

The bend radius of the Ethernet cable is limited. For details, see the specifications of the Ethernet cable to be

used.

(g) Network configuration

For wiring, check Page 49, Section 5.1.1 (2) and Page 51, Section 5.1.1 (3) to prevent incorrect wiring

Identify the error stations on baton pass status (each station) (SW00A0 to

SW00A7). The following actions are taken on error stations.

• Replace the Ethernet cable.

• Adjust the total number of slave stations set to the master station (safety

station) to the number of connected slave stations.

• Check if the station set in the network configuration setting of GX Developer

matches with the connected station.

• Set the station number for the station where a station number is not set.

• Replace the master/local modules.

The network is not configured in ring topology or is incorrectly configured.

( Page 49, Section 5.1.1 (2))

Check connection status of stations between the stations specified at Loopback

station number 1 (SW0070) and Loopback station number 2 (SW0071), and

connected Ethernet cables.

To use a network configuration other than the ring topology, clear the "Use"

checkbox under "Loopback Function Setting" in the network parameter window

for the master station (safety station).

CHAPTER 7 PARAMETER SETTING

(1) Link Scan Mode Setting

Item Description

Asynchronous

Link scan is performed asynchronously with the sequence scan of the safety CPU module. Select this item to shorten input transmission delay time when sequence scan takes much time than link scan. Note that output transmission delay time will become longer.

Constant Scan

Cyclic transmission is performed punctually. Link scan time will be the constant link scan time set in this setting. However, when the actual link scan time is longer than the specified link scan time, cyclic transmission is performed by actual link scan time.

While constant link scan is used to keep link scan time constant, the transmission delay time is not kept constant by this function. To keep transmission delay time constant, select "Synchronous".

Synchronous

Link scan is performed synchronously with the sequence scan of the safety CPU module. Select this item in the following cases:

• To shorten output transmission delay time (Note that when sequence scan takes much time than link scan, input transmission delay time will become longer.)

• To keep transmission delay time constant

(2) Precautions

When "Synchronous" is set under "Link Scan Mode Setting" of "Supplementary Setting", observe the following.

• Change the program or the system configuration so that the sequence scan time of the safety CPU module

may be within 200ms. Failure to do so may cause disconnection of slave stations.

• Set the sequence scan time of safety CPU modules on local stations (safety stations) so that it may be

longer than or equal to the link scan time.

If the sequence scan time is shorter than the link scan time, an error occurs in safety communication. To

avoid this, set the constant scan time of the safety CPU modules on the local stations (safety stations).

For how to calculate link scan time, refer to Page 303, Appendix 5.2.

For how to set the constant scan time of a safety CPU module, refer to the following.

*1 Routing parameters need not to be set for stations for which routing parameters are not available (e.g. station including

a head module). The station communicates with other networks according to routing parameters set to the master station.

● Transient transmission range Communications can be made with stations up to eight networks apart (number of relay stations: 7).

● Setting for stations that do not perform transient transmission to other networks Routing parameters are not required for stations that do not perform transient transmission to other networks; however, setting the same routing parameters to all stations is recommended.

It is recommended to set the same routing parameters as for .

and can communicate by the same routing parameters, since they pass through the same relay station.

Note that routing parameters need not to be set for stations for which routing parameters are not available (e.g. station including a head module). The station communicates with other networks according to routing parameters set to the master station.

(2) Checking method

To check whether routing parameters have been correctly set and transient transmission can be performed,

perform a communication test from CC-Link IE Field Network diagnostics. ( Page 75, Section 6.4.3)

(3) Precautions

(a) Different control CPUs are set to the network modules on a relay station in a

multiple CPU system

Set the same routing parameters to all the control CPUs.

7.7 Routing Parameters

Set the same routing parameters.

Safety data transfer

(1) Safety communication flow

After a safety connection is established, safety data is sent periodically from safety stations on both stations.

The device status in the safety CPU module on a station (sending side) is stored into a device in the safety CPU

module on the other station (receiving side). The figure below is an example of safety communication between a

master station (safety station) and a local station (safety station). Safety communication between local stations

(safety station) is also the same.

• Output from a master station (safety station)

The device in the safety CPU module on a master station (safety station) turns on.

The device status in the safety CPU module on the master station (safety station) is stored into the

device in the safety CPU module on the local station (safety station) by safety data transfer.

• Output from a local station (safety station)

The device in the safety CPU module on a local station (safety station) turns on.

The device status in the safety CPU module on the local station (safety station) is stored into the

device in the safety CPU module on the master station (safety station) by safety data transfer.

(2) Setting method

Assign devices to be used for safety communication in the safety communication setting.

( Page 90, Section 7.6)

Devices used for safety communication are highlighted in yellow or green in ladder programs on GX Developer.

( GX Developer Version 8 Operating Manual (Safety Programmable Controller))

The following figure is an example of a ladder program with a device highlighted in yellow.

Highlighted in yellow

● If an error occurs in safety communication, safety data from a station with an error is cleared.

● A safety connection can be established only while baton bass is performed after configuring the safety communication

setting of both stations (sending side and receiving side).Note that stations not set to the network configuration setting of the master station and reserved stations cannot establish a safety connection. Check whether a safety connection is established or not at special registers (SD1420 to SD1427) (Safety refresh communication status of each safety station) and a special relay (SM1421) (Safety refresh communication status of safety master station).

( QSCPU User’s Manual (Function Explanation, Program Fundamentals))

● The following data can be held only when the safety CPU mode is set to the test mode: output data of safety

communication when the safety CPU module is on the STOP status. ( Page 115, Section 8.2.6)
