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

Depending on the circumstances, procedures indicated by CAUTION may also cause severe injury.

It is important to follow all precautions for personal safety.

Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.

[DESIGN PRECAUTIONS]

WARNING

● Make sure to set up the following safety circuits outside the PLC to ensure safe system operation even during external power supply problems or PLC failure. Otherwise, malfunctions may cause serious accidents.

Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the equipment at the upper and lower positioning limits).

Note that when the CPU module detects an error, such as a watchdog timer error, during selfdiagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU module occurs in an input/output control block, output control may be disabled. External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

Note that the output current of the 24 V DC service power supply varies depending on the model and the absence/presence of extension modules. If an overload occurs, the voltage automatically drops, inputs in the PLC are disabled, and all outputs are turned off. External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

Note that when an error occurs in a relay, triac or transistor of an output circuit, the output might stay on or off. For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

● Construct an interlock circuit in the program so that the whole system always operates on the safe side before executing the control (for data change) of the PLC in operation.

Read the manual thoroughly and ensure complete safety before executing other controls (for program change, parameter change, forcible output and operation status change) of the PLC in operation.

Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.

● In an output circuit, when a load current exceeding the current rating 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.

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

● 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.

[DESIGN PRECAUTIONS]

CAUTION

● When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current

(approximately ten times greater than normal) may flow when the output is turned from off to on. Take proper measures so that the flowing current dose not exceed the value corresponding to the maximum load specification of the resistance load.

● 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 this variation in time.

● Simultaneously turn on and off the power supplies of the CPU module and extension modules.

● If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned off. When the power supply is restored, it will automatically restart (when the RUN/STOP/RESET switch is on the RUN side).

Outline

1.1

Outline of the MELSEC iQ-F Series

Designed on the concepts of outstanding performance, superior drive control and user centric programming, Mitsubishi’s

MELSEC-F Series has been reborn as the MELSEC iQ-F Series.

From stand alone use to networked system applications, MELSEC iQ-F Series brings your business to the next level of industry.

Outstanding Performance

CPU Performance

A new sequence execution engine is at the core of MELSEC iQ-F, capable of running structured programs and multiple programs, and supports structured text and function blocks, etc.

High-speed System Bus Communication

MELSEC iQ-F realizes high-speed system bus communication at speeds of 1.5 k words/ms (approx. 150-times faster than

FX3U). Achieve maximum performance even when using intelligent function module with large amounts of data.

Security

MELSEC iQ-F has advanced security functions (file password, remote password, security key) to prevent data theft and illegal operations by unauthorized persons.

Superior Drive Control

Built-in Positioning

MELSEC iQ-F features powerful positioning functionality with 8 ch high-speed pulse input and 4-axis pulse output. Positioning operations including interrupt, variable speed, and simple interpolation can easily be set up in tables and executed.

Simple Motion Module (FX5-40SSC-S)

By connecting the Simple Motion module (FX5-40SSC-S) equipped with a 4-axis positioning function compatible with

SSCNET/H, and combining linear interpolation, 2-axis circular interpolation and continuous trajectory control in the program set with a table, a smooth trajectory can be easily drawn.

By starting with parameter settings and the PLC program, the Simple Motion modules can realize a variety of motion control including positioning control, advanced synchronous control, cam control and speed-torque control.

Improved Programming Environment

User-friendly Programming Software (GX Works3)

■System design with a convenient parts library

With GX Works3, designing a system is as easy as preparing the module configuration diagram by dragging and dropping selected parts.

■Auto-generation of module parameters

When preparing the module configuration diagram, simply double-click the module to automatically generate the module parameters. A window with an easy-to-use parameter settings screen opens, enabling module parameters to be modified as needed.

Replacement from FX3U to FX5U

2.1

Outline

FX5U, which is the successor model of the FX3U, is equipped with analog functions, communication and high-speed input/ output etc., and can easily be expanded with expansion boards and expansion adapters. The high-speed system bus communication brings out the maximum performance of extension modules equipped with intelligent functions.

The procedures and points for replacing to the successor model FX5U are shown below. Please consider replacement with the information.

Points to Consider

• The “recommended substitute models” are described for individual FX3U and extension modules that can be replaced by iQ-F Series models. According to usage and system configuration (connection status of the extension modules), and cases when the I/O numbers actually used are small, other models than the described “recommended substitute models” may be suitable for replacement.

• The recommended substitute models for extension modules, function expansion boards and built-in batteries are described with those that can be connected to the FX5U CPU module.

• Contents that require special caution when replacing each model are described in “Special notes”. Most recommended substitute models have various differences in specifications other than those in “Special notes” such as the dimension becoming smaller than the current models. Therefore, when considering usage, please check not only the “Special notes” but also the details of each specification for the dimension and power specifications etc., in the manual.

• Based on the above conditions, “No recommended substitute models” is described for those without a recommended substitute model, but there are cases that can be replaced with an FX5U system configuration according to usage and system configuration. Check the necessary functions and features when considering the replacement with FX5U system configuration.

The procedures and points for replacing to the successor model FX5UC are shown below. Please consider replacement with the information.

Points to Consider

• The “recommended substitute models” are described for individual FX3UC and extension modules that can be replaced by iQ-F Series models. According to usage and system configuration (connection status of the extension modules), and cases when the I/O numbers actually used are small, other models than the described “recommended substitute models” may be suitable for replacement.

• The recommended substitute models for extension modules and built-in batteries are described with those that can be connected to the FX5UC CPU module.

• Contents that require special caution when replacing each models are described in “Special notes”. Most recommended substitute models have various differences in the specifications other than those in “Special notes” such as the dimension becoming smaller than the current models. Therefore, when considering usage, please check not only the “Special notes” but also the details of each specification for the dimension and power specifications etc., in the manual.

• Based on the above conditions, “No recommended substitute models” is described for those without a recommended substitute model, but there are cases that can be replaced with an FX5UC system configuration according to usage and system configuration. Check the necessary functions and features when considering the replacement with FX5UC system configuration.

GX Works3 only supports the GX Works2 format projects of FX3U/FX3UC.

When converting project data other than FX3U/FX3UC, change the PLC type to FX3U/FX3UC using GX

Works2. After changing the PLC type, check that there is no error using GX Works2, and then convert to

MELSEC iQ-F using GX Works3.

Precautions

• The projects cannot be read out from the CPU module of FX3 Series using GX Works3. To read out the projects, use GX

Works2 to read out. (GX Works2 is supplied with GX Works3.)

• To read out projects of GX Works2 using GX Works3, convert beforehand using GX Works2, and then read out the projects.

Even for projects converted using GX Works2, conversion may not be performed according to the state of the project. If there is an error in the program, read out will be canceled.

Precautions when Converting the Projects

When converting projects of the FX3 Series using GX Works3, be careful because the program (instructions and devices) may be changed.

Instruction Replacement List

When converting the projects of the FX3 Series to MELSEC iQ-F projects, the instructions may be changed. They are described below also with the precautions.

Precautions of Instruction Replacement

■Function with "_E"

For functions with “_E”, the positions of the parameters are different between GX Works2 and GX Works3. Therefore the projects must be modified after conversion.

• GX Works2: EN is specified for the first parameter and "ENO" is the return value.

• GX Works3: EN is specified for the first parameter, ENO is specified for the second parameter, and the result is the return value. (The value is the same as function without "_E".)

■Data types of parameters

The parameter data type of some instructions, functions, function blocks of GX Works2, and the parameter data type of the instructions, functions, function blocks of GX Works3 are different. Therefore, an error may occur because of data type mismatch when reusing the program of GX Works2. In that case, modify the instruction name and parameter.

Ex.

INC instruction

• When handling a value exceeding 32767 (maximum value of word [signed]), replace to “INC_U”.

• When word [unsigned]/bit array [16-bit] type label is specified for the parameter, replace to “INC_U”.

■Instructions/FB/FUN that are not supported by the MELSEC iQ-F Series

For the instructions/FB/FUN that are not supported by the MELSEC iQ-F Series, refer to the following manual to correct the program so that the instructions/FB/FUN will be equivalent to the one in the manual.

Action content

The connecting position of the parameter is different from GX

Works2.

After replacing to FX5, select the appropriate instruction and perform

“Edit”

 ”FB/FUN update” in the right-click menu, and then adjust the connecting position.

When an out of range “I” device is specified as parameter “i”, parameter

“i” will be replaced with P4095.

■Correction of structured ladder/FBD program

• The method of thinking for execution order is different for the GX Works2 structured ladder/FBD and GX Works3 FBD/LD language. Display the execution order and check the contents.

• The operation of the return element is different for the GX Works2 structured ladder/FBD and GX Works3 FBD/LD language. For details of the return element of GX Works3, refer to the following.

GX Works3 Operating Manual

• For the GX Works2 structured ladder/FBD and GX Works3 FBD/LD language, there are different cases in the input/output parameter numbers of the function parts/function block parts. In this case, it will be displayed as an undefined FB/FUN.

Select [Edit]

[FB/FUN update] to update the definition information, and correct the program.

41

• When the program is made to refer to a standard FB member in the GX Works2 structured ladder/FBD, a conversion error may occur after opening with GX Works3. In this case, check the member name and class of the standard FB, and correct the program.

• For the GX Works3 FBD/LD language, the input/output parameter of the function parts/function block elements can only be inverted. When elements other than the above are inverted for GX Works2 structured ladder/FBD, the connecting line of that element will be deleted. Correct the program so that the operation will be equal to GX Works2 structured ladder/FBD.

• For the GX Works3 FBD/LD language, the wired OR of the FBD elements are not supported. Correct the program so that the operation will be equal to GX Works2 structured ladder/FBD, or a conversion error will occur.

• When using the pointer branch instructions (CJ), jump, and sub routine program, a conversion error may occur. For details, refer to the following.

MELSEC iQ-F FX5 Programming Manual (Program Design)

• According to the difference of the GX Works2 structured ladder/FBD editor and GX Works3 FBD/LD editor, the layout of the program may change. Correct the layout appropriately.

• Ladder block label used in the GX Works2 structured ladder/FBD will be defined as a pointer type in local label.

Precautions

Index modification of the S device (state) cannot be made on the MELSEC iQ-F. Replace as follows.

• When the S device without state management has its index modified, replace to M device to use.

• When the S device used for state management has its index modified and used for the ZRST instructions, program the

ZRST instructions for each batch-clear pattern.

The assigned device of the global label cannot be read out.

• Information of the assigned device in GX Works2 is input in the comment field. Refer to the comment field to assign the device again.

• When special M and special D have been assigned, they will be replaced and assigned to SM and SD.

If S device is set to the device memory data or device initial data created using GX Works2, it will be deleted.

If there is a device that is not supported by the MELSEC iQ-F Series in the program created using GX Works2, the device will be changed to SM4095/SD4095.

The default value is set to the parameter setting of device points.

4.3

Precautions when Replacing the Parameters

When converting projects of the FX3 Series to MELSEC iQ-F projects, the setting data of the parameters (PLC parameter and network parameter) and special module (intelligent function module) will be deleted. Therefore, it is necessary to reset the data with GX Works3.

Also, GX Works3 does not support the following parameters of the FX3 Series, so it is necessary to set with the PLC program.

• Network parameter (CC-Link)

• Intelligent function module parameter (AnyWireASLINK)
