Creation of multiple initial steps is possible
Multiple processes can easily be executed and combined. Initial steps are linked using a "selection coupling" format. When
multiple initial steps (S0 to S3) are active, the step where the transition condition (t4 to t7) immediately prior to the selected
coupling is satisfied becomes inactive, and a transition to the next step occurs.
Moreover, when the transition condition immediately prior to an active step is satisfied, the next step is executed in
accordance with the parameter settings.
Basic model QCPU, Universal model QCPU, and LCPU cannot be selected in the parameter setting. It
operates in the default "Transfer" mode.
• Wait: Transition to the next step occurs after waiting for the next step to become inactive.
• Transfer: Transition to the next step occurs even if the next step is active. (Default)
• Pause: An error occurs if the next step is active.
Linked steps can also be changed at each initial step.
