Processing details
• This instruction deactivates the specified step in the specified block.
• When the number of active steps in the specified becomes 0, the specified block will be inactive. If the block start/end bit of
the SFC information device is set, the corresponding bit device turns off.
• If the instruction is executed to an inactive step, the instruction is ignored.
• If no block is specified, the following block is targeted depending on the execution program type.
• Sequence program: Block 0
• SFC program (within the action): Block where the instruction is executed (current block)
