13.1 SFC Control Instructions
Precautions
• In a simultaneous sequence, specify and activate all the steps by using the SET instruction (Activating a step). If there is
any inactive step left, a convergence is not performed. Likewise, if the RST instruction (Deactivating a step) is executed to
a single step in a simultaneous sequence, a convergence condition is not satisfied.
• The current step No. cannot be specified within the action of the SFC program. If specified, an error occurs.
