[Design Precautions]

WARNING

● Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting

operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.

(2) When the programmable controller detects an abnormal condition, it stops the operation and all

outputs are:

• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.

• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU module detects an error such as a watchdog timer error.

(3) All outputs may be turned on if an error occurs in a part, such as an I/O control part, where the

CPU module cannot detect any error. To ensure safety operation in such a case, provide a safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit example, refer to "General Safety Requirements" in the MELSEC iQ-R Module Configuration Manual.

(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an

output circuit. Configure an external circuit for monitoring output signals that could cause a serious accident.

● In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

● Configure a circuit so that the programmable controller is turned on first and then the external power supply. If the external power supply is turned on first, an accident may occur due to an incorrect output or malfunction.

● For the operating status of each station after a communication failure, refer to manuals relevant to the network. Incorrect output or malfunction due to a communication failure may result in an accident.

[Design Precautions]

WARNING

● When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper operation may damage machines or cause accidents.

● Especially, when a remote programmable controller is controlled by an external device, immediate action cannot be taken if a problem occurs in 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.

● Do not write any data to the "system area" and "write-protect area" of the buffer memory in the module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to each module. Doing so may cause malfunction of the programmable controller system. For the "system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the module used.

● If a communication cable is disconnected, the network may be unstable, resulting in a communication failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire system will always operate safely even if communications fail. Failure to do so may result in an accident due to an incorrect output or malfunction.

● To maintain the safety of the programmable controller system against unauthorized access from external devices via the network, take appropriate measures. To maintain the safety against unauthorized access via the Internet, take measures such as installing a firewall.

● Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) Machine home position return is controlled by two kinds of data: a home position return direction

and a home position return speed. Deceleration starts when the proximity dog signal turns on. If an incorrect home position return direction is set, motion control may continue without deceleration. To prevent machine damage caused by this, configure an interlock circuit external to the programmable controller.

(2) When the module detects an error, the motion slows down and stops or the motion rapidly stops,

depending on the stop group setting in parameter. Set the parameter to meet the specifications of a positioning control system. In addition, set the home position return parameter and positioning data within the specified setting range.

(3) Outputs may remain on or off, or become undefined due to a failure of a component such as an

insulation element and transistor in an output circuit, where the module cannot detect any error. In a system that the incorrect output could cause a serious accident, configure an external circuit for monitoring output signals.

● If safety standards (ex., robot safety rules, etc.,) apply to the system using the module, servo amplifier and servomotor, make sure that the safety standards are satisfied.

● Construct a safety circuit externally of the module or servo amplifier if the abnormal operation of the module or servo amplifier differs from the safety directive operation in the system.

[Design Precautions]

CAUTION

● Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100 mm or more between them. Failure to do so may result in malfunction due to noise.

● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current (approximately ten times greater than normal) may flow when the output is turned from off to on. Therefore, use a module that has a sufficient current rating.

● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies depending on the system configuration, parameter settings, and/or program size. Design circuits so that the entire system will always operate safely, regardless of the time.

● Do not power off the programmable controller or reset the CPU module while the settings are being written. Doing so will make the data in the flash ROM and SD memory card undefined. The values need to be set in the buffer memory and written to the flash ROM and SD memory card again. Doing so also may cause malfunction or failure of the module.

● When changing the operating status of the CPU module from external devices (such as the remote RUN/STOP functions), select "Do Not Open by Program" for "Opening Method" of "Module Parameter". If "Open by Program" is selected, an execution of the remote STOP function causes the communication line to close. Consequently, the CPU module cannot reopen the line, and external devices cannot execute the remote RUN function.

[Installation Precautions]

WARNING

● Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

1.1 Fixed Cycle Communication

The communication cycle of the Simple Motion module is fixed cycle. The communication is performed with slave modules in

a cycle set in the inter-module synchronization cycle setting.

Refer to the following for details. MELSEC iQ-R Inter-Module Synchronization Function Reference Manual

1.2 CC-Link IE Field Network Synchronous

Communication Function

A slave module which supports the CC-Link IE Field Network synchronous communication function operates synchronously

with the inter-module synchronization cycle of the Simple Motion module (the communication cycle of CC-Link IE Field

Network). Therefore, the operation timing between the Simple Motion module and each slave module can be synchronized.

A slave module which does not support the CC-Link IE Field Network synchronous communication function is also

connectable. However, the operation is not synchronized with the inter-module synchronization cycle of the Simple Motion

module. Therefore, the operation timing of the slave module is not synchronized with the Simple Motion module.

The link refresh is performed to the area set in "Refresh Settings" under "Basic Settings" and also specified in "Network

Configuration Settings" under "Basic Settings".

(1) Range set in "Refresh Settings" under "Basic

Settings" (2) Actual link refresh range (3) Range set in "Network Configuration Settings"

under "Basic Settings"

Shortening the link refresh time and transmission delay time

The link refresh time and transmission delay time can be shortened by reducing the number of link refresh points to the CPU

module. The following methods can be used to reduce the number of the link refresh points.

• In "Refresh Settings" under "Basic Settings", set only the link devices used in the CPU module as the link refresh range.

(Page 70 Refresh Settings)

• Directly access infrequently used link devices from the program, and remove the corresponding settings from the link

refresh range. (Page 23 Direct access to link devices)

Setting method

The link refresh is assigned in "Refresh Settings" under "Basic Settings". (Page 70 Refresh Settings)

Precautions

■Latched devices of the CPU module

If data in latched devices of the CPU module are cleared to zero on a program when the CPU module is powered off and on

or reset, the data may be output without being cleared to zero, depending on the timing of the link scan and link refresh. Take

the following actions not to output the data in the latched devices of the CPU module.

CPU module device How to disable the device data

Latch relay (L), file register (R, ZR) Use the initial device value of the CPU module to clear the device to zero.

CPU module device within the latch range Delete all the latch range settings specified in "Latch Interval Operation

Setting" under "Device Latch Interval Setting" in "Memory/Device Setting" of "CPU Parameter".

*1 For the initial device value setting of the CPU module, refer to the following.

GX Works3 Operating Manual

When the inter-module synchronization setting is set to "Not Use", the link device (RX/RY/RWr/RWw) of the

Shortening the link refresh time and transmission delay time

■Shortening the link refresh time

Remove infrequently used link devices from the link refresh range, and directly read or write the corresponding data using link

direct devices. This reduces the number of the link refresh points to the CPU module, resulting in a shorter link refresh time. (Page 21 Link refresh)

■Shortening the transmission delay time

Because the link direct device allows direct reading or writing of data to the link devices of the Simple Motion module at the

time of the instruction execution, the transmission delay time can be shortened.

Link refresh is executed in END processing of the sequence scan of the CPU module.

Precautions

■Cyclic data integrity assurance

Direct access to link devices does not provide station-based block data assurance. Use 32-bit data assurance, or if cyclic data of more than 32 bits needs to be assured, use interlock programs. (Page 26 Cyclic data integrity assurance)

■Mounting multiple modules of the same network No.

When multiple Simple Motion modules of the same network No. are mounted, the target of direct access is the module which

has the smallest slot No. in the base unit.

■Link direct device in a multiple CPU system

In a multiple CPU system, link direct devices cannot be used for the CC-Link IE Controller Network-equipped module

controlled by another CPU module.

Output status setting for CPU STOP

When the CPU module mounted with the Simple Motion module is set to STOP, whether cyclic data output is held or cleared

can be selected.

Setting method

Under "Supplementary Cyclic Settings" in "Application Settings", set the output status for the case where the CPU module switch is set to STOP. (Page 74 Application Settings)

Precautions

■When the setting is disabled

When the link refresh source of RY is set to Y, the cyclic data output is cleared even if the output status setting for CPU STOP

is set to be held. For RWw, the cyclic data output is held regardless of the device of the link refresh source, even if the output

status setting for CPU STOP is set to be cleared.

■When the output status setting for CPU STOP is set to clear

When the CPU module is in the STOP state, the forced output to slave stations cannot be executed using the engineering

tool.

■When data is refreshed by a link direct device

The output status for CPU STOP depends on the parameter specified in "Output Hold/Clear Setting during CPU STOP" under

"I/O Maintenance Settings" under "Supplementary Cyclic Settings" in "Application Settings".

■When the Safety CPU is used

When the Safety CPU is in the safety mode, output of safety communications will be cleared even if "Hold" is set in "Output

Hold/Clear Setting during CPU STOP" of "I/O Maintenance Settings" under "Supplementary Cyclic Settings" in "Application

Settings".

• When the Ethernet device is a personal computer (only Ethernet devices having the route command, such

as Microsoft Windows), it is recommended to set the gateway address using the route command. If the

gateway address is set in the default gateway, packets not related to the IP packet transfer are also

transmitted through the CPU module. Consequently, the service processing of the CPU module drops under

heavy load, causing other service processings to be slow or other problems. For the gateway address

setting of when an Ethernet device is connected to a module other than an Ethernet-equipped module, refer

to the manual for the module connected to the Ethernet device.

• After the setting is completed, execute the IP communication test to check for an error in the communication

path. (Page 47 IP communication test)

• When an Ethernet device (request destination device) is connected to an Ethernet-equipped module, the

communication path to a master/local module, remote head module, or the Ethernet-equipped module

connected to the Ethernet device (request destination device) can be checked using the IP communication

test. Setting the IP address of the Ethernet device in "Communication Target" on the "IP Communication

To check whether other modules support the IP packet transfer function, refer to the following. User's manual for the module used

Using different networks

Communications cannot be performed via modules that do not support the IP packet transfer function such as MELSECNET/

Communications before a baton pass is established (D LINK LED off)

The IP packet transfer function can be used after a baton pass was established. If communications are performed before that,

a timeout error occurs in an Ethernet device (request source device). Whether the baton pass is established in the own station

can be checked on the D LINK LED.

Precautions when using the UDP communication

Using UDP may reduce the reliability of data communications compared to TCP, causing a problem, such as data missing and

changed order of data receiving. If any problem occurs, change the protocol to TCP.

Communications of Broadcast and Multicast

Communications of Broadcast and Multicast cannot be transferred using the IP packet transfer function. Use Unicast

Precautions

• This function may detect an error and stop safety communications if the data link is reconfigured during safety

communications.

• If an error occurs in safety communications, safety data from the station with an error is cleared.

• A safety connection between the master station (safety station) and local station (safety station) or between local stations

(safety stations) can be established only while baton bass is performed after configuring "Safety Communication Setting"

under "Application Settings" of both stations (sending side and receiving side). The baton pass status can be checked in

"Baton pass status of own station" (SB0047).

• A safety connection with the remote device station (safety station) can be established only while data link is performed after

configuring the "Safety Communication Setting" under "Application Settings" of the master station. The data link status can

be checked in "Data link status of each station" (SW00B0 to SW00B7).

• Note that stations not set in "Network Configuration Settings" under "Basic Settings" of the master station (safety station)

and reserved stations cannot establish a safety connection.

• Safety communications cannot be performed among the Simple Motion modules set in the same control CPU.

• This function may detect an error and stop safety communications if a parameter is written to the control CPU of the Simple

Motion module during safety communications.

Safety station interlock function

When a communication error has occurred between safety stations, communication is automatically cut to prevent incorrect

input or output from the faulty station. Safety communications between the stations becomes safety station interlock state,

and it does not resume until the safety interlock is released.

Create a program which releases the interlock by using Interlock release request for each safety connection to release the

safety station interlock state.

Note that standard communication automatically resumes even in the safety station interlock state if the communication error

cause is eliminated.

The safety station interlock function prevents equipment stopped by a communication error from suddenly resuming its

operation after it recovers from the error.

Checking method

Precautions

■Device set to "CPU Side"

Set a device range not to overlap the one used for the following:

• "Refresh Settings" in "Basic Settings" of other network modules

• "Link Refresh Settings" in "Basic Settings" of a CC-Link master/local module

• I/O Nos. used for I/O modules and intelligent function modules

• "Refresh settings" of intelligent function modules

• "Refresh Setting between Multiple CPUs" of "CPU Parameter" for a multiple CPU system

■Link refresh range

• Set only link devices used in the CPU module for link refresh range. Doing so will reduce link refresh points, resulting in a

shorter link refresh time.

• Do not include RWw of the servo amplifier (motion mode) in the link refresh range. The error "Network refresh setting error"

(error code: 3065H) occurs and the READY signal [X0] is not turned ON.

• When the inter-module synchronization setting is set to "Not Use", the link device (RX/RY/RWr/RWw) of the station whose

network synchronous communication is set to "Synchronous" is not refreshed.

When the software version of the Simple Motion module is "Ver.05":

When the control CPU is a safety CPU, the refresh setting of RWw of the servo amplifier (motion mode) is not

checked.

Do not include RWw of the servo amplifier (motion mode) in the refresh range. If it is included, the operation

will be failure such as that the servo ON is not executed.

■Changing link device assignment in "Network Configuration Settings" of "Basic Settings"

Correct the set range in "Refresh Settings" of "Basic Settings".
