This instruction activates the specified block, and executes a step sequence starting from an initial step.
■Execution condition
■Description, range, data type
■Applicable devices
*1 The BL can be index modified.
• 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.
• The RnCPU and RnENCPU with firmware version "12" or later support this instruction. (Use an engineering tool with version "1.015R" or later.)
• The RnPCPU (process) with firmware version "03" or later supports these instructions. (Use an engineering tool with version "1.020W" or later.)
