Relation between various controls and block start data

The "block start data" must be set to carry out "high-level positioning control".
The setting requirements and details of each "block start data" item to be set differ according to the "[Da.13] Special start
instruction" setting.
The following shows the "block start data" setting items corresponding to various control methods.
Also refer to the following for details on "condition data" with which control execution is judged.

[Da.14] Parameter
*1 The "NEXT Start" instruction 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.
It is recommended that the "block start data" be set whenever possible with the engineering tool. Execution by
a program uses many programs and devices. The execution becomes complicated, and the scan time will
increase.
