Block Programming Instructions Section 3-30
3. If CIO 0.03 is OFF after “B” is executed, the rest of the block program will
not be executed until CIO 0.03 turns ON. When CIO 0.03 turns ON, “C” will
be executed and the execution process will be repeated.
The following table shown the relationship between the operand bits and block
program execution.
As shown in this example, WAIT(805) and WAIT(805) NOT can be used to
progressively execute steps within a block program.
