Explanations:

NOP instruction does not conduct any operations in the program; therefore, after the execution of NOP,

the existing logical operation result will be kept. If the user wants to delete a certain instruction without

altering the length of the program, the user can use NOP instruction. If the user wants to delete a

certain instruction temporarily, the user can also use NOP instruction.

y Flags: None

Operands:

: The destination pointer of conditional jump

Explanations:

1. When the user does not wish a particular part of DOP-EXIO program in order to shorten the scan

time and execute dual outputs, CJ instruction or CJP instruction can be adopted.

2. When the program designated by pointer P is prior to CJ instruction, WDT timeout will occur and

DOP-EXIO will stop running. Please use it carefully.

3. CJ instruction can designate the same pointer P repeatedly. However, CJ and CALL cannot

designate the same pointer P; otherwise an error will occur.

Program Example 1:

1. When X0 = On, the program automatically jumps from address 0 to N (the designated label P1)

and keeps its execution. The addresses between 0 and N will not be executed.

2. When X0 = Off, as an ordinary program, the program keeps on executing from address 0. CJ

instruction will not be executed at this time.

Program Example 2:

1. CJ instruction can be used in the following 5 conditions between MC and MCR instructions.

Without MC ~ MCR.

b) From without MC to within MC. Valid in the loop P1 as shown in the figure below.

c) In the same level N, inside of MC~MCR.

d) From within MC to without MCR.

e) Jumping from this MC ~ MCR to another MC ~ MCR

Page 84

Appendix D Use of Application Instructions|DOP-EXIO Series

Revision March, 2008, Doc. Name: 2007PDD23000014 D-3

2. When CJ instruction is used between MC and MCR, it can only be applied without MC ~ MCR or

in the same N layer of MC ~ MCR. Jumping from this MC ~ MCR to another MC ~ MCR will result

in errors, i.e. a) and c) as stated above can ensure correct actions; others will cause errors.

MC N0

M1000

MCR

Program Example 3:

1. The status of each device when executing CJ instruction:

¾ The method of using this CJ instruction is similar to the method of using goto instruction of

C-language. When executing CJ instruction, the status of each device will not be changed.

¾ When the timers are driven and encounter the execution of CJ instruction, the timing will

resume. After the timing target is reached, the output contact of the timer will be On.

¾ The counter will stop counting (This is because the counter is activated to count via the

software).

¾ All the instructions which have encounterd the execution of CJ instruction will not be

activated.

2. Y1 is a dual output. When M0 = Off, Y1 is controlled by M1. When M0 = On, Y1 is controlled by

M12.

2. CALL must be written after FEND instruction and add SRET instruction in the end of its

subroutine. Interruption program has to be written after FEND instruction and IRET must be

added in the end of the service program.

3. If several FEND instructions are in use, place the subroutine and interruption service programs

between the final FEND and END instruction.

4. After CALL instruction is executed, executing FEND before SRET will result in errors in the

program.

5. After FOR instruction is executed, executing FEND before NEXT will result in errors in the

Explanations:

1. FOR instruction indicates FOR ~ NEXT loops executing back and forth N times before escaping

for the next execution.

2. N = K1 ~ K32,767. N is regarded as K1 when N ≤ 1.

3. When FOR~NEXT loops are not executed, the user can use the CJ instruction to escape the

loops.

4. Error will occur when

a) NEXT instruction is before FOR instruction.

b) FOR instruction exists but NEXT instruction does not exist.

c) There is NEXT instruction after FEND or END instruction.

d) The number of instructions between FOR ~ NEXT differs.

5. FOR~NEXT loops can be nested for maximum five levels. Be careful that if there are too many

loops, the increased PLC scan time may cause timeout of watchdog timer and error. Users can

use WDT instruction to modify this problem.

Program Example 1:

After program A has been executed for 3 times, it will resume its execution after NEXT instruction.

Program B will be executed for 4 times whenever program A is executed once. Therefore, program B

will be executed 3 × 4 = 12 times in total.

regard the value as negative binary values.

Program Example:

1. Designate device Y0, and operand D automatically occupies Y0, Y1, and Y2.

2. When X10 = On, CMP instruction will be executed and one of Y0, Y1, and Y2 will be On. When

X10 = Off, CMP instruction will not be executed and Y0, Y1, and Y2 remain their status before

X10 = Off.

Explanations:

1. When this instruction is executed, the content of S will be moved directly to D. When this

2. If the operation result refers to a 32-bit output, (i.e. application instruction MUL and so on), and

the user needs to move the present value in the 32-bit high-speed counter, DMOV instruction has

to be adopted.

Program Example:

1. MOV instruction has to be adopted in the moving of 16-bit data.

a) When X0 = Off, the content in D10 will remain unchanged. If X0 = On, the value K10 will be

moved to D10 data register.

b) When X1 = Off, the content in D10 will remain unchanged. If X1 = On, the present value T0

will be moved to D10 data register.

2. DMOV instruction has to be adopted in the moving of 32-bit data.

When X2 = Off, the content in (D31, D30) and (D41, D40) will remain unchanged. If X2 = On, the

present value of (D21, D20) will be sent to (D31, D30) data register. Meanwhile, the present
