Safety Precautions

: Incorrect handling of the device may result in minor injury or physical damage.

Be sure to read the "Safety Precautions" thoroughly before using the module.

Here, the safety precautions items are classied into "Warning" and "Caution".

Warning

: Incorrect handling of the device may result in death or serious injury.

Caution

Even some items indicated by "Caution" may result in a serious accident. Both safety instruction categories provide important information. Be sure to strictly observe these instructions.

Warning

 Neve touch any part of charged circuits as terminals and exposed metal portion while the power is turned ON. It may result in an electric shock to the operator.  Turn OFF the power before mounting, dismounting, wiring, maintaining or checking, otherwise, electric shock, erratic

operation or troubles might occur.

 Place the emergency stop circuit, interlock circuit or the like for safety outside the PLC. A failure of the PLC might break or cause problems to the machine.  When using an expansion right side unit, be sure to mount a healthy unit to stop the SPF system with a fatal fault if the

expansion right side unit is dropped. Unless a healthy unit is mounted, a dropout of the expansion right side unit is not detected and the SPF system continues operation in the state where the expansion right side unit is dropped.

Safety Precautions

Caution

 Do not use one found damaged or deformed when unpacked, otherwise, fire, failure or erratic operation might be caused.  Do not shock the product by dropping or tipping it over, otherwise, it might be damaged or troubled.  Follow the directions of the instruction manual and user’s manual when mounting the product.

If mounting is improper, the product might drop or develop problems or erratic operations.  Use the rated voltage and current mentioned in the instruction manual and user’s manual. Use beyond the rated values

might cause fire, erratic operation or failure.

 Operate (keep) in the environment specified in the instruction manual and user’s manual. High temperature, high humidity,

condensation, dust, corrosive gases, oil, organic solvents, excessive vibration or shock, might cause electric shock, fire, erratic operation or failure.

 Select a wire size to suit the applied voltage and carrying current. Tighten the wire terminals to the specified torque.

Inappropriate wiring or tightening might cause fire, malfunction, failure or might cause the product to drop from its mounting.

 Contaminants, wiring chips, iron powder or other foreign matter must not enter the device when installing it, otherwise, fire,

accident, erratic operation or failure might occur.

 Remove the dust-cover seals of modules after wiring, otherwise, fire, accident, erratic operation or failure might occur.  Connect the ground terminal to the ground, otherwise, electric shock or erratic operation might occur.  Periodically make sure the terminal screws and mounting screws are securely tightened.

Operation at a loosened status might cause fire or erratic operation.

 Put the furnished connector covers on unused connectors, otherwise, erratic operation or failure might occur.  Sufficiently make sure of safety before program change, forced output, starting, stopping or anything else during a run.

Wrong operation might break or cause problems to the machine

 Engage the loader connector in a correct orientation, otherwise, an erratic operation might occur.  Before touching the PLC, discharge any static electricity that may have been collected on your body. To discharge it, touch

a grounded metallic object. Static electricity might cause erratic operation or failure.

 Be sure to install the electrical wiring correctly and securely, observing the directions of the instruction manual and user’s

manual. Wrong or loose wiring might cause fire, accident or failure.

 When disengaging the plug from the outlet, do not pull the cord, otherwiase, break of cable might cause fire or failure.  Do not attempt to change system configurations (such as installing or removing expansion block) while the power is ON,

otherwise, failure or erratic operation might occur.

 Do not attempt to repair the module by yourself, but contact your Fuji Electric agent, otherwise, fire, accident or failure

might occur.

 To clean the module, turn power off and wipe the module with a cloth moistened with warm water. Do not use thinner or

other organic solvents, as the module surface might become deformed or discolored.

 Do not remodel or disassemble the product, otherwise, failure might occur.  Follow the regulations of industrial wastes when the device is to be discarded.  The products covered in this user’s manual have not been designed or manufactured for use in equipment or systems

which, in the event of failure, can lead to loss of human life.

 Do not use the products covered in this user’s manual for special applications, such as power plant, radiation facilities,

railroad, space/flight equipments, lifeline facilities, or medical equipments, where a great effect on human life, body, society, major property or rights may be anticipated and high degree of safety is required.

 Be sure to provide protective measures when using the products covered in this manual in equipment which, in the event

of failure, can lead to loss of human life or other grade results.

 External power supply (such as 24 V DC power supply) which is connected to DC I/O should be strongly isolated from AC

power supply, otherwise, accident or failure might occur. (Use of EN60950 conforming power supply is recommended.)

4) Notes on rewriting programs

When rewriting the program in the main unit from the loader while the PLC is running, the built-in RAM is changed, however, the built-in ash memory is unchanged. As a result, the contents of the RAM does not match those of the ash memory, and the RUN/MEM LED blinks to prompt the user to transfer the contents of the RAM to the ash memory. After rewriting the program, be sure to transfer the contents of the RAM to the ash memory. When the transfer is completed

normally, the RUN/MEM LED turns OFF.

By using the loader, transfer the contents of the RAM to the ash memory.

After rewriting the program, turn OFF the main unit and then ON again. When the power supply is turned ON, the contents of the RAM is automatically transferred to the ash memory.

1-3-2 Input/output memory area

The input/output memory area is a window through which data are exchanged between the main unit (user application) and external devices. This area is used by input devices such as pushbuttons, switches, and sensors which send data to the main unit and by output devices such as relays, solenoids, and indicators which show the results of program executions.

Key points:

1) Input is represented by %I (prex), and output by %Q (prex). When actually assigning an I/O address, these prexes

are followed by a size and address in the variable declaration. For details, see “1-4 I/O Address Assignment.”

2) Both input and output cannot exist in the same word.

1-3-3 Standard memory area

The standard memory area is used for auxiliary relays that are used internally in the PLC.

Key points:

1) In the direct addressing mode, this memory area is specied in he format of %Mo1. ... (replace o with any of X, W, or D).

Usually, since a variable declaration is used to assign memory to an application program, you may neglect addresses in programming. See “1-5 variables” for details.

2) The specied memory area is reset to (0) zero when self-PLC is started.

3) 4K words from the top of the standard memory is the area where data access in the CPU is processed at high speed.

4) The sizes of the standard memory areas can be changed taking those of other areas into account. Note that the size of

the high-speed access memory area is xed to 4K words and cannot be changed. For the details of memory size change, see “3-3-2 CPU memory size denition.”

5) No continuous access is allowed to the high-speed access memory area and the boundaries between other areas. For example, an array or structure cannot lie across the boundary

1-3-6 System FB instance memory area

The user FB memory area is a real memory area dedicated to the system FBs such as timers, counters, and differential instructions that are used internally in the PLC.

Key points:

1) At PLC startup, predened initialization is performed. (the old values are retained or reset to 0s (zeros).

Example) The current values for the counters and additional timers and the old value for the edge detect instruction counter are retained, while the current values for the timers (excluding additional) are reset to 0s (zeros).

2) Eight words/timer, four words/counter, and two words/edge detect instruction counter are used.

3) The size of the system FB instance memory area can be changed taking those of other areas into account.

For the details of memory size change, see “3-3-2 CPU memory size denition.”

4) By default, the numbers of timers, additional timers, counters, and edge detect instruction counters have been preset per main unit. If necessary, you can change these numbers.

Timer

Main unit with 14/24 points 256 points 0 point 256 points 1024 points 512 words

Main unit with 32/40/60 points 512 points 0 point 512 points 2048 points 1024 words

To set the timer, additional timer, counter, edge detect, and other system FB areas, the following conditions must be met.

(No. of timers) × 8 words + (No. of counters) × 4 words + (No. of edge detect counters) × 2 words + Others <= Preset size of system FB instance memory area

1-4 I/O Address Assignment

1-4-1 Rules for assigning I/O addresses

In MICREX-SX series SPF, follow the rules below to assign I/O addresses.

Prefix

Input : %IX (bit), %IW (word), %ID (double word)

Unit No.

Word No.

Bit address

(0 to 15)

(1) Unit No.

A number (1 to 6) is assigned to SPF expansion right side units, in their connected order. The number assigned to the main unit

is always “0” (zero). The front board is assigned “100” (xed) as an independent unit and the expansion left side unit with “200” (xed).

Expansion left side unit

Unit No. 200

Main unit

Unit No. 0

Front board

Unit No. 100

Expansion right side unit

Unit No. 1

Expansion right side unit

Unit No. 2

Expansion right side unit

Unit No. 3

(2) Word No. and bit address

To each SPF unit, words starting from the word 0 (zero) are assigned for the number of words that the unit occupies. No same word is assigned to both input and output. Therefore, for main units and expansion units with both inputs and outputs, words are

assigned rst to inputs and then to outputs. The main unit occupies eight words of the I/O area (input: four words, output: four

words).

1-5 Variables

1-5-1 Overview of variables

MICREX-SX series is a PLC that conforms to IEC61131 (programming language standards of programmable controllers). Its application program realizes control through “program code worksheet” in which the logic operation of a program is described and “variables worksheet” in which the allocation of hardware and memories to use is described. Because hardware and control logic can be separated by coding a program with variables, it is possible to make highly reusable application programs.

1-5-2 Variable declaration

Variables are declared in tabular format as shown below.

Specify the initial value of the variable.

Enter the variable name.

Specify the data type.

* Each column can be hidden if necessary. For details, refer to the user’s manual “SX-Programmer Expert (D300win) <Reference> (FEH257).”

Enter the variable comment. Assign an address to the variable.

Specify the type of the variable.

To specify the variable as “retain,” check this box.

(1) Usage of variables

Usage Description

VAR Declarative statement for local variable

VAR_INPUT Declarative statement for function / function block input variable

VAR_OUTPUT Declarative statement for function block output variable

VAR_IN_OUT Declarative statement for function block input/output variable

VAR_EXTERNAL Declarative statement for global variable to be used in POU

VAR_GLOBAL Declarative statement for variables that can be used in whole project (global variable)

MICREX-SX series allow the user to split an application program into blocks for individual processing function of a system. However, considering the modularization of application program, the variables that can be used only in a certain program (POU) are necessary. On the other hand, in order to Maintain the relationship between programs (POUs), the variables that can be used in any POU are also necessary. For MICREX-SX series, the variable that can be used only in one POU is referred to as “local variable”; the variable that can be used in any POU, as “global variable”. Global variables are declared on the global variable worksheet, and local variables are

declared on the local variable worksheet. To use a global variable in a POU, “VAR_EXTERNAL” is set for variable type to call

the global variable in the local variable worksheet.

(2) Assigning variables to memory

When variables are declared and complied on the variables worksheet, they are assigned to the CPU internal memory. There are two methods for assigning variables: the method that user species arbitrary address of the CPU internal memory (AT specication) and the method that D300win allocates CPU internal memory during compilation.

User species address to I/O memory.

User species address to

CPU internal memory.

D300win automatically allocates CPU internal memory.

For the variables to which no address is specied on the variables worksheet, D300win assigns addresses during compilation

according to the following rules:

• When user assigns variables to standard memory (high-speed), standard memory and retain memory, it is necessary to

specify addresses in the AT range.

• When no address is set in the “Address” column on the variables worksheet, D300win assigns addresses, from the top one in

order, that are out of the AT range of standard memory or retain memory.

AT range

Out of AT range

AT range

Out of AT range

AT range

Out of AT range

Standard memory

Retain memory

1) When user assigns a variable, such as variable “ERROR”, to standard memory, an address out of the AT range of standard memory is specied.

2) When user species no address, like variables “Condition 1” and “Condition 2”, variables are assigned to the top one in order

of the addresses out of the AT range in the high-speed area of standard memory. If there is no longer an area to allocate in the out-of-AT range of high-speed area, variables are assigned to the out-of-AT range of standard memory.

3) When user assigns a variable to retain memory (power-failure data retentive memory), like variable “Set_value_0”, an address in the AT range of retain memory is specied.

4) If user species no address, like variables “Condition 3” and “RUN”, when the “RETAIN” box is checked, variables are

assigned to the top one in order of the addresses that are out of the AT range of retain memory.

Notes:

AT range is determined by default but can be changed by resource setting.

For details, see “3-3-2 CPU memory size denition.”

addresses

(AT specication), assign them to even addresses.

Retain memory

(3) Retaining variables during power failure

The variables that are so set as to be retained during power failure (the variables assigned to reMain memory) are reset at cold start (when started up initially from D300win) and retained at warm start (when started up from D300win or when the unit is powered up). There are two methods for retaining variables during power failure:

• Check the [Retain Type] box on the variable worksheet.

a The variable is assigned to an address out of AT range in the retain memory during compilation.

• Assign the variable to an address within AT range.

AT range

Out of AT range

Notes:

1) When assigning a variable to a memory, address specication is given priority. Therefore, even when the [Retain Type] box is checked for a variable for which AT is specied in the standard memory area, the variable won’t not be retained during

power failure (the variable is not assigned to the retain memory.)

2) In the following cases, the data of retain memory is cleared and the unit comes in cold start operation mode.

• When started up for the rst time after user ROM with different memory allocation was installed

• When started up for the rst time after memory backup error occurred

• When started up for the rst time after the resources were initialized

• When started up for the rst time after the data memory in this area was cleared

• During battery-less operation

(4) Setting initial value for variable

When initial value is set for a variable, the set initial value is assigned to the variable when PLC application program is started (during the rst scan). Initial value is set in the [Initial Value] column on the variable worksheet.

Notes:

When initial values are set, 2.5 steps are consumed for one value from the end of program memory area in order. If there is no

free area in the program area, no initial value can be set for variable.

(5) Restrictions on variable names

• Only a symbol “_” may be used for a variable name. Note that no “_” can follow the variable name.

• No digit can be used at the top of a variable name.

• Up to 30 characters can be used for a variable name.

• No space can be used for a variable name.

• The words reserved for the system (data type names, instruction names, etc.) cannot be used.

1-6-3 Derived data types

Derives data types are dened by user or PLC manufacturer. They are dened on the worksheet in the “Data Type” folder of the

project tree. The MICREX-SX series supports the following derived data types:

• Array data types 1-dimensional array 2-dimensional array (array of array)

• Structured data types Structure Array of structures Structure of arrays, structure of structures

(1) Array data types

An array is made up of two or more elements of the same data type. Arrays may be either 1- or 2-dimensional arrays.

Data type “INT_1_10” is made up of 10 integers that are indexed from 1 to 10.

Notes:

Signed integers are legitimate values. Consequently, negative integers such as “-10” are allowed.

The data type of variable “SET_DATA” is INT_1_10.

Notes:

Derived data types such as array variable must be assigned to the address of even number.

Section 1 Specications

Data type “x_data” is made up of 10 integers that are indexed from 1 to 10 and data type “y_data” is made up of 3 instances of “x_data,” indexed from 1 to 3.

The data type of variable “FILE_01” is y_data.

Page 61

Section 1 Specications

(2) Structured data types

A structured data type is made up of two or more similar or different data types. Structured data type is used in situations where data items of different data types are necessary for a single operation. Structured data type may be contained in an array (array of structures) or contain arrays (structures of arrays).

The structured data type “machine” consists of ve data types, namely, X_POS (UDINT), Y_POS (DINT), DEPTH (UINT),

RPM (UINT), and FLAG (BOOL).

The data type of variable "hole_pro" is machine.

Variables of a structured data type are accessed in the form of <variable name>.<member name>. Examples of

<member name> in the above example are X_POS, Y_POS, DEPTH, RPM, and FLAG. To access the rotational speed (RPM) in hole_pro, you specify hole_pro. RPM.

1-52

Page 62

Section 1 Specications

Structures may be contained in an array.

The example shown below denes an array of 10 machines, indexed from 1 to 10, which are dened in the above example.

The data type of variable “num_hole_pro” is machine_1_10.

Structures in an array are accessed in the form of <variable name>[<array index>].<member name>. Examples of <member

name> in the above example are X_POS, Y_POS, DEPTH, RPM, and FLAG. For example, in order to access the 5th row (RPM) of num_hole_pro, “num_hole_pro[5].RPM” is specied.

Array is dened as an element of a structure.

The example shown below denes a structure “machine2” of which the “DEPTH” member is an array of depths. of depths.

The data type of variable “hole_pro_02” is machine2.

An array in a structure is accessed in the form of <variable name>.<member name>[<array index>]. To access the 5th depth

in the member “DEPTH” of “hole_pro_02,” you specify hole_pro_02.DEPTH[5].

Page 63

Section 1 Specications

For derived data type variable, such as array variable and structure variable, no initial value can be set on the variable worksheet. The assignment of initial value to derived data type variable is made by application program.

(3) Restrictions on derived data types

• Derived data types can be assigned no initial values in their declarations. Initialize array/structure data type variables by an

application program.

• Derived data type variable cannot be overwritten online.

• Neither array data type variables nor structure data type variables can be monitored on the program. Therefore, when

debugging a program that references array data type or structure data type variables, it is necessary to register them with the watch list and debug the program using the watch list.

• If the value for a variable is out of the range of array elements specied in the data-type denition when array numbers are

specied using variables, data at the highest or lowest array element number are accessed.

1-7 Tasks

A task is a time schedule for program execution. Tasks determine the sequence (time schedule) of program execution. For the MICREX-SX SPF series, the following three types

of tasks are provided: default task for cyclic processing, xed cycle tasks, and event tasks.

Programs that will always be executed need be assigned to tasks so that their execution sequence can be determined.

* After a startup request is issued, xed cycle tasks and event tasks are executed according to priority during execution of a user

program of the default task.

1-7-2 Types and operations of tasks

1) Default task

• Always repeat execution. Assign programs requiring no responsibility and periodicity in arithmetical operations.

• Maximum 64 programs can be assigned.

• With the constant scan function, it becomes possible to make default task synchronous.

Notes:

A user WDT is the timer which monitors the execution time of the default task. It checks the time when execution has be done. When no default task is used, the CPU processes the tasks equivalent to the default ones to execute internal processes such as the user WDT check.

Fixed cycle task Event task

2) Fixed cycle task

• Executed once in specied cycle (setting range: from 1ms to 32s, in 1-ms steps). The programs that require high-speed

response in order to follow up control object or the programs that require being executed at constant intervals are assigned to this task.

• A xed cycle task is given a priority of 0 to 19 (0 has the highest priority).

• Maximum 8 programs can be assigned to one task.

3) Event task

• Executed once when event address (specied bit device) is set ON. In addition to ordinary bit devices, the “interrupt input”

and “high-speed counter match interrupt” that are assigned to system memory can be assigned. (Special event address)

• An event task is given a priority of 0 to 19 (0 has the highest priority).

• Maximum 8 programs can be assigned to one event task.

Notes:

For event task, the timing of its start depends on the number of specied event addresses. Above example shows the

operation when special event addresses that use “interrupt input” and “high-speed counter match interrupt” as event addresses

are specied. When input address or the like that is not special event address is specied as event address, the event task is started when the next “xed cycle interrupt by system” occurs after the event occurred.

Checking task execution time and execution cycle

You can check the task execution time and cyclr on the resource information screen that can be displayed from the control dialog of D300win.

Task execution time: The time after input to the task starts until output from the task has been nished.

Task execution cycle: The time after input to the task starts until input to the next task starts.

The task execution cycle is displayed after the resource information screen is opened and then the task is executed twice.

Section 1 Specications

Function name: AAA

The variables in FCT are initialized

1) Function

A function is a program organization unit that, when executed, generates a single data item, including multiple elements such as an array or structure). A function has no internal state, that is, executions of a function with the same input parameters always generate the same

output. Predened functions can be used in other programs, functions, and function blocks.

The value of variables that are used only within a function are unpredictable when the function is called.

VAR A:INT; B:INT; C:INT; D:INT; END_VAR

A:=AAA(B,C);

D:=AAA(B,C);

FCT

VAR_INPUT IN1:INT; IN2:INT; END_VAR VAR TEMP:INT; END_VAR

TEMP:=IN1; TEMP:=TEMP+IN2; AAA:=TEMP; RET

The value is unpredictable when the function is called.

when FCT is called. The output value is assigned to the FCT name.

2) Function block

A function block is a program organization unit that, when executed, generates one or more data items. A function block can

have two or more copies of data which are called instances. Each instance is given an identier called the instance name. An

instance has output, internal, and input variables. Some of the output and internal variables must retain their contents until the function block is called next time. Consequently, a function block does not always generate the same output even when it is called multiple times with the same input parameters. The program that calls a function block can access only the input and output variables of the function block; it can access none of the internal variables of the function block.

Predened function blocks can be used within a program or function block.

The instances of a function block can be referenced only within the program organization unit in which they are declared unless the instances are declared globally.

3) Program

A program is the basic program organization unit for a user application. Only programs can be assigned to tasks (neither functions nor function blocks can be assigned to a task). A program has neither input variables nor output variables.

1-9 Calendar Function

The values of the calendar built in a main unit of the MICREX-SX series SPF can be monitored and set from D300win. They can also be monitored and set from an application program.

1-9-1 Calendar value range

The calendar can measure calendar values from 1970-01-01 00:00:00 through 2069-12-31 23:59:59. Notes: One second after 2069-12-31 23:59:59, the date and time will turn back to 1970-01-01 00:00:00.

1-9-2 Calendar accuracy

The accuracy of the calendar (clock) in a main unit is ±20 seconds per day (at an ambient temperature of 25°C, when active).

Notes:

The accuracy of the calendar varies depending on the environmental conditions such as an ambient temperature.

When a main unit is to be used in a system where a high calendar accuracy is required, measure the actual calendar accuracy

and determine the inspection (clock calibration) period.

1-9-3 How to monitor and set the calendar from D300win

1) Click the [Project Control] button in the menu bar. The “Control” dialog box opens.

Click here.

2) Click the [Calendar/Watch] button to display the current value.

Current values for date and time

Click this button.

Click here.

3) Click the [Change ...] button. The “PLC time setting” dialog box opens. On this dialog box, you can set any desired value.

1-9-4 How to monitor and set the calendar from an application program

1) HW_RTC (Hardware RTC) - Original FB

Use the hardware RTC function block (HW_RTC) to monitor and set the calendar from an application program. For details, see the description of HW_RTC.

Notes:

DT type (date and time type) data should be specied for HW_RTC. The range of DT data is from 1970-01-01 00:00:00 to 2106-02-07 06:28:15. However, the setting range of HW_RTC is from 1970-01-01 00:00:01 to 2069-12-31 23:59:59. (If any date and time after 2070 is specied, an unexpected value will be set.)

To set the calendar using data input from an external device, convert it to DT type. DT type data are equivalent to a 32-bit unsigned integer in seconds that starts at January 1st, 00:00:00, 1970.

Examples:

(1) 1970-01-01 12:34:56 g DINT#45296 WORD#16#0000B0F0 (2) 1998-01-01 00:00:00 g DINT#883612800 WORD#16#34AADC80

2) RTC (real-time clock) - IEC standard FB

The IEC standard function block RTC cannot be used to set the calendar value. If RTC is used to make calendar settings, a relative value to the calendar is set in the instance area and the calendar will run with the set value.

3) Accessing the calendar from SPF original special relay

The “year,” “month,” “day,” “hour,” “minute,” “second,” and “day of the week” data of the built-in calendar are automatically set in the SPF original special register. You can directly access them from an application program. In addition, calendar values can be written to the built-in calendar from the SPF original special register.

Address Name Description

%MW1.61442 Year data

%MW1.61443 Month data Sets the month data of the built-in calendar. (BCD: 01 to 12)

%MW1.61444 Day data Sets the day data of the built-in calendar. (BCD: 01 to 31)

%MW1.61445 Hour data Sets the hour data of the built-in calendar. (BCD: 00 to 23)

%MW1.61446 Minute data Sets the minute data of the built-in calendar. (BCD: 00 to 59)

%MW1.61447 Second data Sets the second data of the built-in calendar. (BCD: 00 to 59)

%MW1.61448 Day of the week data

Address Name Description

%MX1.61449.0 Calendar write request

The set data are written to the calendar at the end of the default task. Set the calendar data and set ON “Calendar write “request” within the same scan.

(BCD: 00 to 99) Example: 17 for 2017

Sets the day of the week data of the built-in calendar.

0: Sun, 1: Mon, 2: Tue, 3: Wed, 4: Thu, 5: Fri, 6: Sat

When this ag is set ON, “year, month, day, time, minute, and second data” set in the “built-in calendar data (%MW1.61442 to %MW1.61447)” are written to the

built-in calendar. This bit is automatically set OFF.

(2) Describing a function in the IL language

To describe a function call in the IL language, specify, as the rst input, the current operation result and, as the operator, the function call instruction (function name) that species the second and subsequent inputs as operands.

1) 1-input function

LD “Input” SQRT ST “Area for storing operation result”

2) 2-input function

LD “First input”

SHL_WORD “Second input”

ST “Area for storing operation result”

3) 3-input function

LD “First input” SEL “Second input,” “Third input” ST “Area for storing operation result”

Notes:

You cannot specify, in the IL language, any function that has the same mnemonic as an IL instruction (e.g. ADD).

Instructions such as “ADD” must always have two xed inputs when they are to be used in the IL language.

Associate a BOOL type operation condition variable with the EN terminal. When the variable associated with the EN terminal is

TRUE (“1”), arithmetical operations are executed, while when FALSE (“0”), they are not performed. (In the above example, an

OUT value remains unchanged.) A TRUE or FALSE value for the operation is output to the ENO terminal. When ENO is TRUE

(“1”), the operation has been normally done and when FALSE (“0”), an error has occurred in the operation.

Notes:

See the descriptions of functions, for EN/ENO behavior.

In D300win, click “Options” in the “Extras” menu to display the “Options” dialog box. Click the “Graphic Editor” tab.

Check “Functions with EN/ENO,” and then click the [OK] button. After this, any function added is shown with EN/ENO enabled
