* The "NEXT start" command is used in combination with "repeated start (FOR loop)" and "repeated start (FOR
condition)". Control using only the "NEXT start" will not be carried out.
The "start block data" must be set to carry out "advanced positioning control". The
setting requirements and details of each "start block data" item to be set differ
according to the " Da.12 Special start command" setting.
The following shows the "start block data" setting items corresponding to various
control methods. The operation details of each control type are explained starting in
section 10.3.2. Also refer to section "10.4 Setting the condition data" for details on
"condition data" with which control execution is judged.
(The "start block data" settings in this chapter are assumed to be carried out using the
AD75 software package.)

REMARK
It is recommended that the "start block data" be set whenever possible with the
AD75 software package. Execution by sequence program uses many sequence
programs and devices. The execution becomes complicated, and the scan times will
increase.
