In a "repeated start (FOR condition)", the data between the "start block data" in which
"6: FOR condition" is set in " Da.12 Special start command" and the "start block data"
in which "7: NEXT start" is set in " Da.12 Special start command" is repeatedly
executed until the establishment of the conditions set in the "condition data".
(The "condition data" designation is set in " Da.13 Parameter" of the "start block data"
in which "6: FOR condition" is set in " Da.12 Special start command".)
Section (2) shows a control example where the "start block data" and "positioning data"
are set as shown in section (1).
