3.1.5 I/O Variable Wait (IOW) Command

! Outline

The I/O Variable Waiting (IOW) command waits until the conditional expression reaches

its designated condition, then proceeds to the next block.

! Detailed Explanation

The IOW command method is shown as follows:

According to the above command, execution waits until the conditional expression

is formed. When this block is complete with a valid condition, it proceeds to the next

block.

• The conditional expression can only be located on the left side.

• If it is bit-type, only the comparison command “= =” can be used. It cannot be used in the

case shown below.

IOW IB000001&IB000002 <>0;

• The ( ) can be used in the conditional expression.

• All comparison commands can be used in conditional expressions other than that of bit-

type.

IOW MW00100+MW00101>1000;

IOW ML00100*3/100>20;

IOW MW00100&MW00101^MW00102= =3355H;

! Program Examples

IOW IB000001&IB000002 = = |;
