Processing details
• This instruction activates the specified block, and executes a step sequence starting from an initial step. When there are
several initial steps, all the initial steps are activated.
• If the block start/end bit of the SFC information device is set, the corresponding bit device turns on.
• If the instruction is executed to an active block, the instruction is ignored and processing will continue.
• If the instruction is executed to an inactive block for which online change is being performed, the instruction is ignored and
processing will continue.
