Description
The IOW command is designated as follows:
IOW IB000001&IB000002= =|;
A B
A: Conditional expression
B: Status
The IOW command causes execution to wait until the conditional expression is satisfied, then
ends the current block and proceeds to the next block.
1. A conditional expression can be written only on the left side.
2. With a bit expression, only = = can be used for the comparison command.
The conditional expression cannot be used.
IOWIB000001&IB000002< >0;
3. Parentheses ( ) can also be used in a conditional expression.
4. Any comparison command can be used if the conditional expression is not a bit expression.
IOWMW00100+MW00101>1000;
IOWML00100*3/100>=20;
IOWMW00100&MW00101∨MW00102= =3355H;
