Instructions for the Motion SFC charts
Any Motion SFC chart that will be meaningless to or conflict with the definition of Y/N transitions will result in an error at the
time of editing (or Motion SFC chart conversion). Their patterns and instructions will be given below.
■When "Shift Y/N" or "WAIT Y/N" is connected as a selective branch or parallel branch
The following patterns result in an error
Description
"Shift Y/N" used as selective branch
"WAIT Y/N" used as selective branch
"Shift Y/N" and "WAIT Y/N" used as parallel branch
"Shift (or WAIT) Y/N" used with other step/transition as parallel branch or
selective branch
■When a coupling precedes "Shift Y/N" or "WAIT Y/N"
Provide "coupling-branch continuation" in between.
Description
Direct coupling with "Shift Y/N" or "WAIT Y/N" is not allowed.
Provide "coupling-branch continuation" in between.
