10.3 Setting the block start data
10.3.1 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 " bl ock 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 variou s
control systems. The operation details of eac h control type are explained starting in
Section 10.3.2. Also refer to Section 10.4 "Setting the condit ion data for details on
"condition data" with which control execution is judged.
(The " block start data" settings in this cha pter are assumed to be carried out using GX
Configurator-QP.)

: One of the two setting items must be set.
: Set when required (Set to " – " when not used.)
: Setting not possible
–: Setting not required (Setting value will be ignored. Use the initial value or a value within the setting range.)
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.
REMARK
It is recommended that the "block start data" be s et whenever possible with GX
Configurator-QP. Execution by sequence program uses many sequence programs
and devices. The execution becomes com plicated, and the scan times will increase.
