(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.

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

● 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) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and

protective interlock circuit for forward/reverse operation or upper/lower limit positioning.

(2) The programmable controller stops its operation upon detection of the following status, and the

output status of the system will be as shown below.

All outputs may turn on when an error occurs in the part, such as I/O control part, where the programmable controller CPU 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 the QCPU User's Manual (Hardware Design, Maintenance and Inspection).

(3) Outputs may remain on or off due to a failure of an output module relay or transistor. Configure an

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

[Design Precautions]

WARNING

● In an output module, 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.

● When connecting a peripheral with the CPU module or connecting an external device, such as a personal computer, with an 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 or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. 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 sequence program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

[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 100mm (3.94 inches) or more between them. Failure to do so may result in malfunction due to noise.

● When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a large current (approximately ten times greater than normal) may flow when the output is turned from off to on. Take measures such as replacing the module with one having 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.

[Installation Precautions]

CAUTION

● Use the programmable controller in an environment that meets the general specifications in the QCPU User's Manual (Hardware Design, Maintenance and Inspection). Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

Incorrect mounting may cause malfunction, failure or drop of the module. When using the programmable controller in an environment of frequent vibrations, fix the module with a screw. Tighten the screw within the specified torque range. Undertightening can cause drop of the screw, short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

When using an extension cable, connect it to the extension cable connector of the base unit securely.

●

Check the connection for looseness. Poor contact may cause incorrect input or output.

● When using a memory card, fully insert it into the memory card slot. Check that it is inserted completely. Poor contact may cause malfunction.

● When using an SD memory card, fully insert it into the SD memory card slot. Check that it is inserted completely. Poor contact may cause malfunction.

● Securely insert an extended SRAM cassette into the cassette connector of a CPU module. After insertion, close the cassette cover to prevent the cassette from coming off. Poor contact may cause malfunction.

● 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 damage to the product. A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module supporting the online module change function is used. Note that there are restrictions on the modules that can be replaced online, and each module has its predetermined replacement procedure. For details, refer to the relevant sections in the QCPU User's Manual (Hardware Design, Maintenance and Inspection) and in the manual for the corresponding module.

● Do not directly touch any conductive parts and electronic components of the module, memory card, SD memory card, or extended SRAM cassette. Doing so can cause malfunction or failure of the module.

● When using a Motion CPU module and modules designed for motion control, check that the combinations of these modules are correct before applying power. The modules may be damaged if the combination is incorrect. For details, refer to the user's manual for the Motion CPU module.

[Wiring Precautions]

WARNING

● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may result in electric shock or damage to the product.

● After installation and wiring, attach the included terminal cover to the module before turning it on for operation. Failure to do so may result in electric shock.

[Wiring Precautions]

CAUTION

● Individually ground the FG and LG terminals of the programmable controller with a ground resistance of 100 or less. Failure to do so may result in electric shock or malfunction.

● Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.

● Check the rated voltage and terminal layout before wiring to the module, and connect the cables correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or failure.

PC CPU module

1 1 1 1

In a multiple CPU system, more than one CPU module is mounted on the main base unit and each CPU module

controls I/O modules and intelligent function modules separately.

QCPUs, Motion CPUs, C Controller modules, and PC CPU modules can be used in multiple CPU systems.

( Page 31, CHAPTER 3)

This manual describes the combinations of CPU modules and communications among CPU modules in a multiple CPU system. For the uses, functions, and instruction availabilities of each CPU module, refer to the following.

Memory capacity can be expanded by using more than one CPU module.

An additional CPU module can expand the following: Program memory Device memory

(a) Distribution of processing

The overall system scan time can be reduced by distributing the high-load processing performed in a single

CPU module over multiple CPU modules.

(b) Distribution of memory

The memory capacity used for the entire system can be increased by distributing the memory areas over

multiple CPU modules.

Programs can be developed easily by distributing the functions, for example, having different CPU modules

control production line A and production line B.

unit

In a multiple CPU system consisting of a QCPU and Motion CPU, sequence control and motion control can be

implemented together to achieve a high-level motion system.

Interaction with Motion CPUs for motion control is enhanced in Universal model QCPUs.

(a) High-speed data transfer between CPU modules

In a multiple CPU system, up to 14K-word data are transferred in parallel with programs between CPU

modules. This enables high-speed data transfer independent of scan time, and shortens the takt time of the

entire system. ( Page 150, Section 6.1.3)

(b) Synchronous processing with a motion control

An interrupt program which is synchronized with the operation cycle of a Motion CPU (multiple CPU

synchronous interrupt program) can be executed. Command input or output from a Motion CPU can be

synchronized with the operation cycle of the Motion CPU, which enables high-speed data transfer independent

of scan time. ( Page 166, Section 6.4)

With the sampling trace function of Universal model QCPUs, the data communications timing with a Motion

CPU can be checked. Timing can also be checked between Universal model QCPUs.

The sampling trace function facilitates the processing for checking the data send/receive timing between CPU

modules, and reduces the time for debugging the multiple CPU system.

Sampling trace result display using a programming tool

The sampling trace of other CPU modules in the multiple CPU system can be executed, by specifying the following CPU modules.

• Universal model QCPU (except the Q00UCPU, Q01UCPU, and Q02UCPU)

• Motion CPU (Q172DCPU(-S1), Q173DCPU(-S1), Q172DSCPU, or Q173DSCPU)

CHAPTER 1 OVERVIEW

(3) Data communications among CPU modules

The following data communications can be performed among CPU modules in a multiple CPU system.

(a) Transferring data among CPU modules

Data can be transferred among CPU modules by setting auto refresh using a programming tool.

( Page 122, Section 6.1.1 to Page 135, Section 6.1.2)

(b) Reading data from other CPU modules

Each CPU module can read data from other CPU modules whenever required using the following instructions.

( Page 150, Section 6.1.3)

• Read instruction from the CPU shared memory in another CPU module

• Cyclic transmission area device (U3En\G)

The QCPU can direct control to the Motion CPU using the following instruction. ( Page 160, Section 6.2)

• Motion dedicated instruction

(d) Reading/writing device data to/from the Motion CPU

The QCPU can read/write device data to/from the Motion CPU using the following instructions.

( Page 162, Section 6.3.1)

• Multiple CPU transmission dedicated instruction

• Multiple CPU high-speed transmission dedicated instruction

(e) Issuing events to the C Controller module or PC CPU module

The QCPU can issue events to the C Controller module or PC CPU module using the following instruction.

( Page 164, Section 6.3.2)

• Multiple CPU transmission dedicated instruction

The Universal model QCPU (except the Q00UCPU, Q01UCPU, and Q02UCPU) can execute the motion

dedicated instruction multiple times in one scan. Since the motion dedicated instruction can be executed

consecutively to different axis numbers, delay time of servo startup intervals can be shortened.

(f) Logging communication data among CPU modules

Communication data among CPU modules can be saved to an SD memory card in CSV format by logging the

cyclic transmission area device (U3EnG) using the data logging function of the CPU module.

The high-speed Universal model QCPU supports the data logging function.

SYSTEM

2.1 CPU Numbers

CPU numbers are assigned to identify CPU modules contained in a multiple CPU system.

A CPU module mounted in the CPU slot of a main base unit will be CPU No.1. CPU No.2, No.3, and No.4 will be

assigned sequentially to the right of CPU No.1.

CPU slot: CPU No.1 Slot 0: CPU No.2 Slot 1: CPU No.3 Slot 2: CPU No.4

(1) Available CPU numbers

Available CPU numbers differ depending on the QCPU used as CPU No.1 and the main base unit used.

( Page 31, CHAPTER 3)

When a Basic model QCPU is used as CPU No.1, the total number of mountable CPU modules is three

(CPU No.1 to No.3). However, when a slim type main base unit (Q3SB) or multiple CPU high-speed

main base unit (Q3

No.1 and No.2).

(3) Checking the host CPU number

The host CPU number of a QCPU is stored in SD395 (Multiple CPU system information). A host CPU number

check program (refer to an example below) should be created. If created, the following status can be checked

easily.

• Incorrect mounting status of the QCPU

• Program writing status to other CPU modules using the programming tool

In the following program, if the QCPU to which the program is written is other than CPU No.1 (if the value in

SD395 is other than "1"), the annunciator (F1) turns on. Accordingly, the USER LED of the QCPU turns on.

The corresponding annunciator number is stored in SD62 (Annunciator number).

CHAPTER 2 CONCEPT OF MULTIPLE CPU SYSTEM

Ex.

2.2 I/O Number Assignment

A multiple CPU system uses the following two I/O numbers.

• I/O numbers used by CPU modules to communicate with I/O modules and intelligent function modules

( Page 27, Section 2.2.1)

• I/O numbers used by CPU modules to communicate with other CPU modules ( Page 30, Section 2.2.2)

2.2.1 I/O numbers of I/O modules and intelligent function modules

In the same way as in single CPU systems, I/O number "00H" is assigned to the I/O module or intelligent function

module mounted to the right of the CPU module. The subsequent I/O numbers are assigned sequentially to the right.

In multiple CPU systems, however, CPU modules may be mounted in slots 0 to 2 as well, and accordingly the start slot

of "00

" varies.

When two CPU modules are mounted

CPU01234567

I/O number: 00

Slot number

2.2 I/O Number Assignment

2.2.1 I/O numbers of I/O modules and intelligent function modules

● Some CPU modules occupy two or more slots. When this type of CPU module is used, the second slot and after are treated as empty slots. In the case of a PC CPU module, for example, the right slot of the occupied two slots is treated as an empty slot having 16 points. (An empty slot occupies 16 points by default.) For this reason, the start I/O number of the module mounted on the right of the PC CPU module will be "10

CPU 0 1 2

Number of

CPU modules: 3

Note that the start I/O number can be changed to "00

Slot number

Empty slot: 00

H to 0FH occupied

" by setting "0 Point" to the number of points for the right slot of the

PC CPU module in PLC parameter ("I/O Assignment").

● The I/O numbers of the multiple CPU system can be checked on the System monitor window using a programming tool.

● In the same way as in single CPU systems, the position of I/O number "00

" can be changed to any slot in PLC

parameter ("I/O Assignment"). ( User's Manual (Function Explanation, Program Fundamentals) for the CPU module used)

2.2 I/O Number Assignment

2.2.1 I/O numbers of I/O modules and intelligent function modules

2.2.2 I/O numbers of CPU modules

In multiple CPU systems, I/O numbers are assigned to each CPU module to specify mounted CPU modules. The I/O

number for each CPU module is fixed at the corresponding slot, and cannot be changed in PLC parameter ("I/O

Assignment").

The following is the list of I/O numbers that can be assigned to CPU modules.

Either a C Controller module or PC CPU module can be mounted on the extreme right of the other CPU

module(s). No CPU module can be mounted on the right of the C Controller module or PC CPU module.

(d) Empty slot setting

Empty slots can be reserved for future addition of CPU modules. Set the number of CPU modules including

empty slots in "No. of PLC" of PLC parameter ("Multiple CPU Setting"). Then, set "PLC (Empty)" to the type of

a target slot in PLC parameter ("I/O Assignment").

Adding a Motion CPU in slot 0 in the future

Adding a PC CPU module in slot 1 in the future

Setting "PLC (Empty)" between CPU modules

CHAPTER 3 SYSTEM CONFIGURATION

● When a Basic model QCPU is used, "PLC (Empty)" can be set between CPU modules. This is useful when adding a Motion CPU to the system where a Basic model QCPU and a C Controller module or PC CPU module are used. No program modification is required because the CPU number of the C Controller module or PC CPU module does not need to be changed even after the new module is added.

● For a CPU module that occupies two slots or more, secure as many empty slots as needed for the module.
