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.

CJ instruction

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
