1.1.1 Outline of structured programs

You can construct two or more programs (program blocks) into one program. Because you can divide the entire machine processing into small sub processes and create a program for each sub process, you can efficiently create a program for a large system.

1. Structured program

Program structuring is a technique to divide the contents of control executed by the PLC CPU into hierarchical small units (blocks) of processing, and then construct a program. By using this technique, you can design a program while recognizing structuring of a sequence program.

1 Outline

Advantages of hierarchical program

• You can examine the outline of a program at first, and then design its details gradually.

• Program blocks located at the lowest level in the hierarchy are extremely simple and highly independent.

Advantages of program consisting of program blocks

• Because the processing of each block is clear, the entire program is easy to understand.

• The entire program can be divided into several blocks that are created by several people.

• The program reusability is improved, and the development efficiency is improved accordingly.

2. Improved reusability of programs

You can save program blocks in a library. Program resources in the library can be shared, and often used again.

FXCPU Structured Programming Manual (Application Functions)

1.1.2 Programming languages

The following programming languages can be used in each program block.

Graphic languages

1. Structured ladder language

This graphic language is created based on the relay circuit design technology. Any circuit always starts from the bus line located on the leftmost. The structured ladder language consists of contacts, coils, functions and function blocks. These components are connected with vertical lines and horizontal lines.

The ST language can describe control achieved by syntax using selective branches with conditional statements and repetition by repetitive statements in the same way as high-level languages such as C language. By using the ST language, you can create simple programs easy to understand.

Y000:=(X000 OR Y000) AND NOT X001; IF X001 THEN D2:=D0; (When X001 is ON, the contents of D0 are transferred to D2.) END_IF; IF X002 THEN D4:=D4+1; (When X002 is ON, the contents of D4 are added by "1".) ELSE D6:=D6+1; (When X002 is OFF, the contents of D6 are added by "1".) END_IF;

1.3 Cautions on Creation of Fundamental Programs

This section explains cautions on programming. Refer to the following manual for cautions on structured programs and programming languages:

→ Q/FX Structured Programming Manual (Fundamentals)

Refer to the following programming manual for detailed operations of and cautions on devices and parameters:

→ FX Structured Programming Manual (Device & Common)

1.3.1 I/O processing and response delay

1. Operation timing of I/O relays and response delay

FX PLCs execute the I/O processing by repeating the processing (1) to processing (3). Accordingly, the control executed by PLCs contains not only the drive time of input filters and output devices but also the response delay caused by the operation cycle.

Acquiring the latest I/O information

For acquiring the latest input information or immediately outputting the operation result in the middle of the operation cycle shown above, the I/O refresh instruction (REF) is available.

(1)

Scan

[Input processing]

Input image memory is read.

(2)

[Program processing]

Image memory of each device is updated.

Batch I/O method (Refresh method)

The ON/OFF status of input terminals is received at one time.

Input image is read, and operation is executed according to program.

(3)

[Output processing]

Result is transferred to output latch memory.

Output devices are driven.

1 Outline

2. Short pulses cannot be received.

The ON duration and OFF duration of inputs in PLCs require longer time than "PLC cycle time + Input filter response delay". When the response delay "10 ms" of the input filter is considered and the cycle time is supposed as "10 ms", the ON duration and OFF duration should be at least 20 ms respectively. Accordingly, PLCs cannot handle input pulses at 25 Hz (= 1000 /(20 + 20)) or more. However, the situation can be improved by PLC special functions and applied instructions.

Convenient functions for improvement

By using the following functions, PLCs can receive pulses shorter than the operation cycle:

• High speed counter function

• Input interrupt function

• Pulse catch function

• Input filter value adjustment function

"Input ON" cannot be received.

1.3.2 Double output (double coil) operation and countermeasures

This subsection explains the double output (double coil) operation and countermeasures.

1. Operation of double outputs

When a coil (output variable) is used twice (double coils) in another program block to be executed or in the same program block, the PLC gives priority to the latter coil.

Suppose that the same coil Y003 is used in two positions as shown in the right figure. For example, suppose that X001 is ON and X002 is OFF.

Input processing X001=ON X002=OFF

1 Outline

Outline

Function List

In the first coil Y003, the image memory is set to ON and the output Y004 is also set to ON because the input X001 is ON.

In the second coil Y003, however, the image memory is set to OFF because the input X002 is OFF.

As a result, the actual output to the outside is "Y003: OFF, Y004: ON".

The SET and RST instructions or jump instruction can be used instead, or a same output coil can be programmed at each state using step ladder instructions STL and RET. When you use the step ladder instructions STL and RET, note that the PLC regards it as double coils if you program, inside the state, an output coil located outside the RET instruction from another program block or the STL instruction.

1.3.4 Handling of general flags

The following flags are valid in general sequence instructions: (Examples) M8020:Zero flag M8021:Borrow flag M8022:Carry flag

M8029:Instruction execution complete flag M8090:Block comparison signal

M8328:Instruction non-execution flag

M8304:Zero flag

*1. Supported only in FX3U/FX3UC PLCs.

*2. Supported only in FX

Each of these flags turns ON or OFF every time the PLC executes a corresponding instruction. These flags do not turn ON or OFF when the PLC does not execute a corresponding instruction or when an error occurs. Because these flags are related to many sequence instructions, their ON/OFF status changes every time the PLC executes each corresponding instruction. Refer to examples in the next page, and program a flag contact just under the target sequence instruction.

M8306:Carry flag

3U/FX3UC/FX3G PLCs.

M8329:Instruction execution abnormal complete flag

FXCPU Structured Programming Manual (Application Functions)

1. Program containing many flags (Example of instruction execution complete flag M8029)

If you program the instruction execution complete flag M8029 twice or more together for two or more sequence instructions which actuate the flag M8029, you cannot judge easily by which sequence instruction the flag M8029 is controlled. In addition, the flag M8029 does not turn ON or OFF correctly for each corresponding sequence instruction. Refer to the next page when you would like to use the flag M8029 in any position other than the position just under the corresponding sequence instruction.

2. Introduction of a method to use flags in any positions other than positions just under sequence instructions

If two or more sequence instructions are programmed, general flags turn ON or OFF when each corresponding instruction is executed. Accordingly, when using a general flag in any position other than a position just under a sequence instruction, set to ON or OFF another device (variable) just under the sequence instruction, and then use the contact of such device (variable) as the command contact.

specified device (shown in the table above) stores the error occurrence step.

• When another error occurs in another step, the stored data is updated in turn to the error code and step

number of the new error. (These devices are set to OFF when errors are cleared.)

• When the PLC mode changes from STOP to RUN, these devices are cleared instantaneously, and then

turn ON again if errors have not been cleared.

3.1 Applied Function Expression and Execution Type

3. Function Construction

This chapter explains the construction of applied functions.

3.1 Applied Function Expression and Execution Type

Applied function and argument

• The name expressing the contents is given to each function.

For example, the function name "SHL (bit shift left)" is given.

• Each function consists of arguments which indicate I/O data used in the function.

SHL_E

EN ENO

D10D0 _IN

_NK1

3 Function Construction

_IN ( ) : An argument whose contents do not change even if the function is executed is called

*1 ( ) : An argument whose contents change when the function is executed is called "destination",

K1 ( ) : Arguments not regarded as source or destination are expressed in "m", "n", etc.

"source", and expressed in this symbol.

and expressed in this symbol.

Argument target devices

• The input variable (label or device) specifies the target.

• Bit device themselves such as X, Y, M and S may be handled.

• Bit devices may be combined in a way "KnX", "KnY", "KnM" and "KnS" to express numeric data.

→ FX Structured Programming Manual (Device & Common)

• Current value registers of data registers (D), timers (T) and counters (C) may be handled.

• When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different from

simple projects. Use labels when handling 32-bit data. You can specify 32-bit counters directly, however, because they have 32-bit length. Use global labels when specifying devices. When 32-bit data is handled, two consecutive 16-bit data registers D are combined. For example, when data register D0 is defined as an argument of a 32-bit instruction by a label, 32-bit data stored in D1 and D0 is handled. (D1 offers high-order 16 bits, and D0 offers low-order 16-bits.) When the current value register of a timer or counter is used as a general data register, it is handled in the same way.

FXCPU Structured Programming Manual (Application Functions)

3.2 Labels

Label types

Labels are classified into two types, global and local.

• Global labels can be used in program components and function blocks.

• Local labels can be used only in declared program blocks.

Label class

The label class indicates how each label can be used from which program component. The table below shows label classes.

Class Description

VAR_GLOBAL Common label available in all program components 33

VAR_GLOBAL_CONSTANT Common constant available in all program components 33

VAR

VAR_CONSTANT

VAR_INPUT

VAR_OUTPUT Label output from a function block 3

VAR_IN_OUT

Label available within declared program components, and not available in any other program component

Constant available within declared program components, and not available in any other program component

Label which receives a value, and cannot be changed in program components

Local label which receives a value, outputs it from a program component, and can be changed in program components

Label definition

It is necessary to define a label to use the label. An error will occur when a program in which labels are not defined is converted (compiled).

• When defining a global label, set the label name, class and data type, and assigns a device.

• When defining a local label, set the label name, class and data type.

You do not have to specify devices for local labels. Assignment of devices is automatically executed during compiling.

In the example below, the label "VAR_D10" is set for the function "BOOL_TO_STR_E".

X000

• When using "VAR_D10" as a global label

Set the class, label name, data type and device (or address).

• When using "VAR_D10" as a local label

Set the class, label name and data type.

QOutput X Bit

M Internal W Word (16 bits)

Size Classification Numbe

2nd character: Size

D Double word (32 bits)

• Memory area position

The memory area position in which data is assigned is classified into "input", "output" or "internal". X(X Device method) : I(Input) Y(Y Device method) : Q(Output) Any other device : M(Internal)

•Size

The principle of the description method corresponding to the device method (MELSEC description method) is as follows: Bit device : X(Bit) Word device : W(Word (16 bits)), D(Double word (32 bits))

• Classification

The 3rd and later characters indicate the device type which cannot be specified only by the position and size explained above. The classification is not required for devices "X" and "Y".

Refer to the following for the device description method:

Cautions

1) Use the function having "_E" in its name to connect a bus.

2) When handling character string data and 32-bit data in structured programs, you cannot specify 16-bit devices directly, different from simple projects. Use labels when handling string data and 32-bit data. You can specify 32-bit counters directly, however, because they are 32-bit devices. Use global labels when specifying labels.
