Setting the Block Start Data

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.
Page 156 Setting the Condition Data
(The "block start data" settings in this chapter are assumed to be carried out using the engineering tool.)
: One of the two setting items must be set.
: Set as required (Set to "" when not used.)
: Setting not possible
: Setting not required (The setting value is invalid. Set the initial value or a value within the setting range.)

[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 times will
increase.
