Introduction
These specifications are the programming manual used when creating the sequence
program with the PLC development software, or Mitsubishi Electric Co.'s integrated FA
software MELSOFT series (GX Developer).
The PLC (Programmable Logic Controller) instructions are largely categorized into the
basic instructions, function instructions and exclusive instructions. There are many types of
instructions. The instructions can be used according to the purpose and application such as
the PLC support function used when supporting the user PLCs.
In addition to the explanation of instructions and functions, the environment to develop the
user PLC using GX Developer, especially the usage unique to MITSUBISHI CNC, is
described. Explanations on the built-in PLC edit function (onboard PLC edit function)
operations are also given.

3. Items related to program development
Always observe the cautions before development to develop a program.
If the data transferred does not follow the file name rule, the CNC will mistake it for another
data, resulting in unexpected operation, e.g. PLC program erasure.
Do not read a sequence program on which a conversion error occurred into the GX
Developer. The file may include unexpected contents to result an illegal operation.
When an error occurred at GX Developer On-line function, the error message may not
explain exactly the state in the CNC side.
Always refer to the error list.

1. Outline
This programming manual is used when creating a sequence program for this CNC using the MELSEC PLC
development software package (GX Developer).
The PLC (Programmable Logic Controller) instructions are largely categorized into the basic instructions,
function instructions and exclusive instructions. There are many types of instructions. The in structions can be
used according to the purpose and application such as the PLC support function used when supporting the
user PLCs.

This program starts periodically at each standard interrupt signal.
This program has the highest level as a program that starts periodically.
It is used in signal processing where high-speed processing is required.
The steps for high-speed processing program should be up to 1000 steps
with basic instructions.
(Application example) Position count control of turret and ATC magazine
(Note) The standard interrupt signal cycle differs according to each model,
and must be confirmed separately.
When the user PLC one-scan process is completed, the next scan process
starts at the next reference interrupt signal cycle.

2.2 Outline of PLC Processing Program
2.2 Outline of PLC Processing Program (Two Program Method)
The MITSUBISHI CNC 700 series program execution control methods include the conventional method
which controls with one program, and the method that splits the program into multiple sections for each
control unit.
When splitting into multiple programs, the order for executing the split programs can be designated on the
setting screen. This is called the multi-programming function.

2.3 Independent Program Method
This method lays importance on compatibility with the conventional models.
One sequence program can be stored. The execution type and head of processing are designated with
reserved labels.
The execution type and execution order cannot be designated on the setting screen.
• Initialization process (reserved label P4003) : This starts up only once when the power is turned ON.
• High-speed process (reserved label P4001) : This starts up at the standard interrupt cycle.
• Main process (reserved label P4002) : This starts up constantly except during the high-speed
process.
2.4 Multi-program Method
Several sequence programs can be registered in the CNC and sequentially executed.
By using this function, the sequence program can be split into each process and developed.
With the multi-program method, the execution type and execution order are designated on the GX Developer
setting screen, and the parameter files are sent to the NC.
The execution type and the head of the process cannot be designated with reserved label s.

2.4 Multi-program Method
2.4.1 Number and Types of Registerable Programs
Up to 20 sequence programs can be registered. Only one execution type can be set in one program. The
following five types of execution types can be used.
• "Initial" (Initialization process) : This starts up only once when the power is turned ON.
• "Scan" (High-speed process) : This starts up at the standard interrupt cycle.
• "Scan" (Main process) : This starts up constantly except during the high-speed process.
• "Standby" (Standby process) : This is called from the high-speed process or main process.
• "Low speed" : This execution type is not used.
2.4.2 Program Execution Order
Several programs are executed in a predetermined order. They are not executed simultaneously. The order
is determined with the development tool (GX Developer or onboard) setting screen. The programs are
executed from the smallest number in the same execution type. An example of the setting screen for GX
Developer is shown below.
The execution order when seven sequence programs are registered in the CNC, as shown in the above
setting screen, is indicated below.

2.6 Storing PLC Processing Program and Execution Mode
2.6 Storing PLC Processing Program and Execution Mode
The user memory area storage method and the PLC processing program execution method are explained.
User memory area is stored in the internal flash ROM (internal F-ROM) and a sequence program is execut ed
according to the following path.
2.6.1 Path from Storage to Execution
(1) During PLC development
Sequence program data transferred from development environment such as GX Developer or PLC
onboard is stored in the volatile RAM (hereinafter, D-RAM) for the temporary memory. The sequence
program is transferred to the PLC processor execution area before PLC executio n, and is then executed.
The D-RAM in the temporary memory is not held when the power is turned OFF. If the data needs to be
held even after the power is turned OFF, it must be stored in the internal F-ROM.
(2) At power ON
The data is transferred from the internal F-ROM to the PLC processor execution area via the temporary
memory D-RAM, and is then executed.
Right after the PLC RUN
instruction, converts into the
MELSEC instruction

2.6.2 Conversion of Instruction Code at Execution
In the internal F-ROM/temporary memory area shown on the left in the figure above, a sequence program is
stored in the instruction code format that is compatible with the MELSEC sequencer. During execution,
however, a sequence program is analyzed to optimize the references and/or converted into the PLC
processing processor instruction code for the CNC. Thus, the length (number of steps) of an instruction for
each instruction changes before and after the conversion. Refer to "6.2 Instruction List" for details on the
number of steps during storage and execution for each instruction.
2.6.3 How to Confirm the Number of Steps at Storage/Execution
The number of steps under the PLC development environment (GX Developer, PLC onboard edit function) is
usually all displayed as the number of steps at "storage".
The number of steps at execution can be checked with some dedicated methods. Refer to "III PERIPHERAL
DEVELOPMENT ENVIRONMENT 5.2.4 (2) How to confirm the size of execution area" or "IV EXPLANATION
OF BUILT-IN EDITING FUNCTION 13.2 (9) EXECUTE STEP" for details.

3.1 Input/Output Signal Types and Processing
The input/output signals handled in user PLC are as follows:
(1) Input/output from/to controller
(2) Input/output from/to operation board (Note 1)
(3) Input/output from/to machine
The user PLC does not directly input or output these signals from or to hardware or controller; it inputs or
outputs the signals from or to input/output image memory. For the reading and writing with the hardware or
controller, the controller will perform the input/output according to the level of the main process or high-speed
process.

3.2 Handling of Input Signals Designated for High-speed Input
The input/output signals used in user PLC are input/output for each program level as shown in the figure
below. In high-speed processing, input/output signal for which high-speed input or output designation
(parameter) is made is input or output each time the high-speed processing program runs. In main
processing, signals other than the high-speed input/output designation are input/output.
When high-speed input designation signal is used in main processing, the input signal may change within one
scan because high-speed processing whose level is higher than main processing interrupts. Input signal
which must not change within one scan should be saved in temporary memory (M), etc., at the head of main
processing and the temporary memory should be used in the main program, for example.

The hatched area is high-speed input designation part. Whenever the high-speed processing program runs,
data is reset in the hatched area. Thus, the signal in the hatched area may change in main processing (A)
and (B) because the high-speed process interrupts between (A) and (B) and re-reads the input signal in the
hatched area.

(2) Extended area
Up to 750 PLC constants can be secured by using the user backup area (R8300 to R9799) as the
extended area. The extended area start register and n umber can be set with the parameters. A total of
900 PLC constants can be set with 150 (#18001 to # 18150) in the basic area and up to 750 (#18151 to
#18900) in the extended area.
Set up data is stored in a file register and is backed up. In contrast, if data is stored in the file register
corresponding to PLC constant by using sequence program MOV instruction, etc., it is backed up.
However, display remains unchanged. Display another screen once and then select the screen again.
750 PLC constants are set (the setting range is ±8 digits). (Signed 4-byte binary data)

5. Explanation of Devices
(3) Setting the timer setting value from the setting and display unit
The timer T setting value can be set with the following two methods.
• Method to validate the setting value (Kn) programmed with the sequence program (Fixed timer)
• Method to validate the setting value set from the setting and display unit (Variable timer)
(Note that even when this method is used, the setting value (Kn) must be programmed in the
sequence program. In this case, the Kn value will be ignored during the operation. When a data
register D is used for the setting value, the contents of the data register D will be the setting value
regardless of the parameter.)
(a) Methods for setting the number of fixed timer and variable timer points
The ratio of the fixed timer and variable timer in all of the timer T points can be set with the bit
selection parameter.
The boundary of the two setting methods is set using 100 points of the timer as one unit. This setting
is validated when the PLC is restarted.

All points (0 to 703) 0 1 1 1 Use all points as variable timer
(b) Variable timer validity setting bit on program side
A bit selection parameter is provided as a switch for the variable timer to invalidate all of the setting
values set from the setting and display unit and validate the setting values in the sequence program.
This setting is valid when the PLC is restarted. (This bit is valid also for the integrated timer.)

(c) Methods for setting the setting value from the setting and display unit
The timer and counter setting value can be set from the parameter setting screen. Steps 1 to 4 also
apply for the counter.
1) The set value is validated when the PLC is restarted.
2) On the setting screen, only the number of variable timer points set with (a) are valid. The (a)
setting is immediately reflected on the display of the settable range.
3) The setting screen values are not affected even if the (b) "variable timer validity setting bit on
program side" setting is changed.
4) It is possible to judge whether the setting value is valid within the current storage ladder
(whether that timer is used with the setting value (Kn) in the ladder).
5) The timer type (10ms, 100ms) can be judged on the setting screen.

5.3.9 Counter C
(1) The counter counts up and detects the rising edge of the input conditions. Thus, the count will not take
place when the input conditions are ON.
Counter C
(a) The value is set with a decimal, and can be designated from 1 to 32767. The data register D or
file register R data can be used as the setting value.
(b) The counter count value will not be cleared even if the input conditions turn OFF. The counter
count value must be cleared with the RST instruction.
(c) When the bit selection parameter is set, the counter current value (count value) will be held even
when the power is turned OFF. Note that some cannot be held depending on the version of
CNC.
(2) With the device C, the contact/coil is handled as bit device, and the current value (counter value) is
handled as word device. In the function instructions described after, the word device C indicates the
current value (counter value) even if there is no description about it.
(3) The counter C setting value can be set with the following two methods.
(a) Method to validate the setting value (Kn) programmed with the sequence program (Fixed counter)
(b) Method to validate the setting value set from the setting and display unit (Variable counter)
(Note that even when this method is used, the setting value (Kn) must be programmed in the
sequence program. In this case, the Kn value will be ignored during the operation. When a data
register D is used for the setting value, the contents of the data register D will be the setting value
regardless of the parameter.)
The ratio of the fixed counter and variable counter in all of the counter C points can be set with the bit
selection parameter.
Number of points Range Bit 7 Bit 6 Bit 5 Bit 4
The bit selection parameter is set using 40 counter poi nts as one unit.
A bit selection parameter is provided as a switch for the variable counter to invalidate all of the setting
values set from the setting and display unit and validate the setting values in the sequence program.
(Refer to the explanation on the timer.)

5.3.14 Pointer P
(1) What is a pointer?
A pointer is a device u se d with branch instructions. A total of 2048 points is used in all executed
programs.
The reserved pointers use the 4000 addresses separately.

(3) Types of pointers
The details of the pointers differ according to the program method.
(a) Independent program method
The following two types of pointers are used.
• General pointer : Pointer which can jump or call with a jump instruction or subroutine call
• Reserved pointer : Pointer with fixed application, such as a start label
X10
instruction
CALL P33
Pointer
RET
Execute sub-routine
program designated with
label P33 when X10 turns
(b) Multi-program method
The following three types of pointers are used.
• Local pointer : Pointer used independently in each program
• Common pointer : Pointer which can be called with subroutine call instruction from all programs
being executed
• Reserved pointer : Pointer with fixed application, such as an END label
II - 28
Page 48
5. Explanation of Devices
5.3 Detailed Explanation of Devices
5.3.14.1 General Pointers
General pointers are pointer which can be used only with the independent program method, which lays
importance on compatibility with conventional models.
The general pointer can be used with the jump instructions and subroutin e call instruction s. The same poin ter
No. cannot be used.
5.3.14.2 Local Pointers
Local pointers are pointers that can be used only with the multi-program method.
(1) What is a local pointer?
(a) A local pointer is a pointer that can be used independently with each program stored in the CNC
controller. The local pointer can be used with the jump instructions and subroutine call instructions.
(b) The same pointer No. can be used in each program.
The pointers from P0 to the common pointer usage range setting value (explained later) can be
used.
Program A
CALL P0
Program B
CALL P0
The same pointer
can be used.
FEND
P0
RET
END
(2) Concept of number of local pointer points
The local pointers split and use the local pointer area (arbitrarily settable with user settings) in all
programs. Up to the maximum No. of local pointers in use can be used in each program. When using the
local pointers in multiple programs, start use from P0.
An error will occur if the total of local pointers used in each program exceeds the setting number.
Program A
Use P0 to P99
in the program
100 points from P0 to
P99 are occupied
Program B
Use P100 to P199
in the program
200 points from P0 to
P199 are occupied
P0
Program C
Use only P249
in the program
250 points from P0 to
P249 are occupied
FEND
RET
END
Total of 550 points
are used
When P0 to P99 are
used, only 100
points are occupied.
When P0 is
used, only one
point is occupied.

5.3.14.3 Common Pointers
Common pointers are pointers that can be used only with the multi-program method.
(1) What is a common pointer?
(a) A common pointer is a pointer that calls the subroutine program from all programs executed with the
CNC controller.
The common pointer can be used only with the subroutine call instruction, and cannot be used with
the jump instruction.
(b) The same pointer No. cannot be used as a label.
Program A
Program C
Program B
(2) Common pointer usage range
The common pointer usage range can be set with the GX Developer parameter settings. The range
following the set No. is the common pointers. The range that can be set as the head No. of the common
pointer is P0 to P2047. The default value is set to 1800, and P1800 to P2047 can be used as common
pointers.

Reserved pointers are pointers with fixed applications.
(1) Independent program method
P4001 (high-speed) : Start label for PLC high-speed processing program.
P4002 (medium-speed) : Start label for PLC main (ladder) processing program.
P4005 (END) : Label indicating END.
P4005 (END) can be used as a device for the CJ instruction, etc., but cannot be used as a label.
In addition, it cannot be used for a CALL instruction device.

[CAUTION]
1. Do not omit the P4002 (medium-speed) label even when using only the PLC main processing
program.
2. Do not use P4001 (high-speed) or P4002 (medium-speed) as a CJ instruction or CALL instruction
device.
3. Do not program to jump to P** in the PLC high-speed processing program from the PLC main
processing program.
4. P** used as a CJ instruction or CALL instruction device must be programmed so that it is in the same
program file as the label instruction.
The PLC will not run properly if even one of Cautions 1 to 4 is not observed.

5. Explanation of Devices
(2) Multi-program method
(a) Label indicating END (P4005)
P4005 is used as the CJ instruction jump destination, and cannot be used as a normal label. It also
cannot be used as the CALL instruction call destination.
If CJ P4005 is executed when multiple PLC programs are registered with the multi-programming
function, the process will jump to the end of all PLC programs (in other words, the scan process is
canceled).
To jump to end of all processes

The following two methods of jumping to the end of each program are available.
• Sets the local pointer right before the END instruction and jumps to that position.
• Executes GOEND instruction. (Usable only with the extended instruction mode)

[Cautions for pointers in multi-program method]
1. Each process (initialization, high-speed, main) is executed from the head of the program executed at
the start of each process.
Thus, the reserved labels for starting, used with the conventional models, cannot be used.
2. The common pointers can be used only with subroutine call instructions, and cannot be used with
jump instructions.
3. The labels using the CJ instruction, JMP instruction or CALL instruction as a device must be
programmed so that one of the following exists.
• If the pointer is a local pointer, it must exist in the same program file as the used instruction.
• If the pointer is a common pointer, it must exist in one of the registered program files.
The PLC will not run properly if even one of Cautions 1 to 3 is not observed.

6.1 Compatible Instructions and Extended Instructions
The following two PLC instruction modes are available with this CNC. Characte ristics and setting method s for
these instructions are explained here.
• Compatible PLC instruction mode (Usable model: 700 Series, 70 Series type A/type B)
• Extended PLC instruction mode (Usable model: 700 Series, 70 Series type A)
(1) Outline and differences of each mode
"Compatible PLC instruction mode" is set when instructions must be compatible with those of the
conventional machine type. In this mode, only the PLC instruction specification which is conventionally
compatible with can be used. If the extended PLC instruction is used, an execution error occurs at the
time of input or edit.
"Extended PLC instruction mode" is set when the extended instruction specification is used. "Extended
PLC instruction mode" includes the specification of "Compatible PLC instruction mode". (Note that
operations may differ for some instructions. Details are explained later.)

6.3 Data Designation Method
6.3.3 Using Double Word Data (32 bits)
Double word data is 32-bit numerical data used by basic instructions and application instructions.
Word devices and bit devices designated by digit designation can be used as double word data.
(1) When using bit devices
Digit designation can be used to enable a bit device to deal with double word data.
Digit designation of bit devices is done by designating "Number of digits" and "Initial numbe r of bit
device".
Digit designation of bit devices can be done in 4-point (4-bit) units, and designation can be made for K1
to K8.
For example, if X0 is designated for digit designation, the following points would be designated:
• K1X0 ….. The 4 points X0 through X3 are designated
• K2X0 ….. The 8 points X0 through X7 are designated
• K3X0 ….. The 12 points X0 through XB are designated
• K4X0 ….. The 16 points X0 through XF are designated
• K5X0 ….. The 20 points X0 through X13 are designated
• K6X0 ….. The 24 points X0 through X17 are designated
• K7X0 ….. The 28 points X0 through X1B are designated
• K8X0 ….. The 32 points X0 through X1F are designated

6.4 Index Qualification
6.4 Index Qualification
Index qualification is an indirect setting made by using an index register.
When an index qualification is used in a sequence program, the device to be used will become the device
number designated directly plus the contents of the index register.
For example, if D0Z2 has been designated, and the content of Z2 is 3, D(2+3), or D5, will become the
designated device.
(1) The index (Z0,Z1) can be set in the range of –32768 to 32767 with a sign added.
(2) The index qualification is used only for the MOV instruction. (DMOV cannot be used.)
(3) The usable instruction format is as shown below.

6.5 Operation Error
6.5 Operation Error
Operation error occurs in the following cases during execution of basic instruction and function instruction.
• In the case where an error described in each instruction's explanation page has occurred:
(1) Device range check
The range check for the devices to be used in basic instruction and function instruction i s as shown bel ow.
(a) If instruction handles a fixed length of device (MOV, DMOV, etc.), device range check will not be
performed. In case that the relevant device range has exceeded, the data is written into another
device.
In such a case indicated below, error will not occur even if D2047 has been exceeded.
DMOV K100
D2047
D2047 and D2048 are supposed to be the
targets; however , since D2048 does not exist, the
contents of the other device will be destroyed.
Device range check will not be performed when index qualification is carried out.
(b) If instruction handles a variable length of device (BMOV, FMOV, etc. that would specify the number of
transfers), device range check will not be performed. In case that the relevant device range has
exceeded, the data is written into another device.
In such a case indicated below, error will not occur even if D2047 has been exceeded.
BMOV K100 D2047
K2
D2047 and D2048 are supposed to be the
targets; however , since D2048 does not exist, the
contents of the other device will be destroyed.
(2) Device data check
Device's data check used for the basic instruction and function instruction is as shown below.
(a) BIN data
• Error does not occur even if the operation result is overflowed or underflowed. At this time, carry flag
does not turn ON either .
(b) BCD data
• Checking as to whether each digit is BCD value (0/ to 9) is performed.
If the digit is other than 0 to 9 (A to F), an operation erro r will result.
• Error does not occur even if the operation result is overflowed or underflowed. At this time, carry flag
does not turn ON either .

6. Explanation of Instructions
6.6 Execution Condition of Instruction
6.6 Execution Condition of Instruction
There are the following 4 kinds of execution conditions for basic instruction and function instruction.
• Execute all the time … Instruction executed regardless of device's ON/OFF
Example: LD X0 , OUT Y10
• Execute at ON … Instruction executed when input condition is turned ON
Example: MOV instruction, CJ instruction
• Execute at rising edge … Instruction executed only at the rising edge (OFF to ON) of input condition
Example: PLS instruction, MOVP instruction
• Execute at falling edge … Instruction executed only at the falling edge (ON to OFF) of input
condition
Example: PLF instruction
With coil equivalent basic instruction and function instruction, if "execution at ON" and "execution at rising
edge" are both possible with the same instruction, add "P" at the end of instruction to differentiate the
execution condition.
• Instruction when executed at ON Instruction name
• Instruction when executed at rising edge Instruction name + P
With MOV instruction, execution at ON and execution at rising edge are specified as shown below.
MOV K4X0 D0

6.7 Counting Step Number
6.7 Counting Step Number
There are the following 2 step numbers. Refer to "2.6 Storing PLC Processing Program and Execution Mode
" for details on the sequence program storage and execution.
(1) Number of steps during storage
This is the number of steps to be consumed when each instruction is stored in F-ROM. This is stored in
the instruction code format which is compatible with the MELSEC sequencer.
Basic number of steps for basic instruction and function instruction is (number of specified devices + 1).
For example, if "+ instruction", the number of steps is as shown below.

6.8 Operations when the OUT, SET/RST, or PLS/PLF Instruction of the Same Device is Used
6.8 Operations when the OUT, SET/RST, or PLS/PLF Instruction of the Same Device is
Used
Operations when multiple OUT instructions, SET/RST instructions or PLS/PLF instructions using the same
device are executed in one scan are explained.
(1) When the OUT instruction of the same device is used:
Do not execute the OUT instruction of the same device multiple times within one scan.
When the OUT instruction of the same device is executed multiple times in one scan, a specif ied device
is turned ON/OFF at the time of each execution of OUT instruction, depending on the operation result up
to the OUT instruction.
Because ON/OFF of the specified device is determined at the time of each execution of OUT instruction ,
ON/OFF may be repeated within one scan.
In the ladder example below, the same internal relay (M0) is turned ON/OFF with the input X0 and X1.

In the case of refresh type CPU unit, when output (Y) is specified with OUT instruction, ON/OFF status of
the OUT instruction executed at the end of 1 scan is output.
(2) When the SET/RST instruction of the same device is used:
(a) The SET instruction turns a specified device ON when the SET command is ON and it does not
operate when the SET command is OFF. Therefore, when the SET instructions of the same device
are executed multiple times within one scan, and if one or more SET commands are ON, the
specified device will be turned ON.
(b) The RST instruction turns a specified device OFF when the RST command is ON and it does not
operate when the RST command is OFF. Therefore, when the RST instructions of the same device
are executed multiple times within one scan, and if one or more RST commands are ON, the
specified device will be turned OFF.
(c) When both the SET instruction and RST instruction of the same device exist within o ne scan, the SET
instruction turns a specified device ON when the SET command is ON, and the RST instruction
turns a specified device OFF when the RST command is ON.
When both the SET command and RST command are OFF, the specified device's ON/OFF status
does not change.

M0 turns OFF

SET executes no
operation because X0 is

(3) When the PLS/PLF instruction of the same device is used:
The PLS instruction turns a specified device ON when the PLS command changes from OFF to ON, and
it turns a specified device OFF when the PLS command changes in a way other than "from OFF to ON"
(which means from OFF to OFF, ON to ON, or ON to OFF). Also, the PLF instruction turns a specified
device ON when the PLF command changes from ON to OFF, and it turns a specified device OFF when
the PLF command changes in a way other than "from ON to OFF" (which means from OFF to OFF, OFF
to ON, or ON to ON). Note that, however, the PLS/PLF command's previous scan status is stored in the
area that is unique to the device specified with the PLS/PLF instruction. Thus, when the PLS/PLF
instruction of the same device is executed multiple times in one scan, the PLS/PLF command status
saved with the first PLS/PLF instruction is used as the second PLS/PLF instruction's PLS/PLF
command's previous scan status. In this way, when the PLS/PLF instruction is executed multiple times in
one scan, the operation may not be carried out in a way as expected by the PLS/PLF instruction.

Program Example
(1) LD is the A contact operation start instruction, and LDI is the B contact operation start
instruction. They read ON/OFF information from the designated device (if a wo rd device bit has
been designated, this becomes the 1/0 status of the designated bit), and use that as an
operation result.
(1) AND is the A contact series connection instruction, and ANI is the B contact series connection
instruction. They read the ON/OFF data of the designated bit device (if a bit designation has
been made for a word device, the 1/0 status of the designated bit is read), perform an AND
operation on that data and the operation result to that point, and take this value as the
operation result.
(1) OR is the A contact single parallel connection instruction, and ORI is the B contact single
parallel connection instruction. They read ON/OFF information from the designated device (if a
word device bit has been designated, this becomes the 1/0 status of the designated bit), and
perform an OR operation with the operation results to that point, and use the resulting value as
the operation result.
REMARK
Word device bit designations are made in hexadecimal. Bit b11 of D0 would be D0.B.

POINT
The method for setting the value of timer T and retentive timer ST includes the
following two ways.
• A method in which the setting value (Kn) programmed by a sequence
program is validated. (Fixed timer)
• A method in which the setting value set with the setting display device is
validated. (Variable timer)

(2) The following program uses the BCD data at X10 to X1F as the timer's set value.
[Ladder Mode]
Converts BCD data at X10 to X1F to BIN and
stores at D10.
When X2 goes ON, the data stored at D10 is
calculated as the set value.
Y15 goes ON when T2 counts up.

REMARK
(1) Only decimal constant (K) can be used for the counter setting value.
Hexadecimal constant (H) cannot be used for the counter setting value.
(1) When the operation results up to the OUT instruction change from OFF to ON, 1 is added to the
present value (count value) and the count up status (present value = set value), and the contacts
respond as follows:
A contact Continuity
B contact Non-continuity
(2) Not counted if the operation result is remained ON. (There is no need to perform pulse conversion on
count input.)
(3) After "present value≧set value" has been realized, the contact state will not be changed until RST
instruction is executed, but the present value is further added by +1.
In this case, the present value is added by +1 up to 65535, and then counted up again by +1 from 0.
(4) A negative number (-32768 to -1) cannot be set as the setting value. If a negative value is set for the
word device, operation is carried out taking the value as a positive value with no signs. If the set
value is 0, the processing is identical to that of when 1 is set.
POINT
(1) Setting the timer setting value using the setting display device.
The method for setting the value of timer T and retentiv e timer ST includes the following two ways.
• A method in which the setting value (Kn) programmed by a sequenc e program is validated.
(Fixed timer)
• A method in which the setting value set with the setting di splay device is validated. (Variable timer)
