10 HIGH-LEVEL POSITIONING CONTROL
10.1 Outline of high-level positioning control
In "high-level positioning control" the execution order and execution conditions of the
"positioning data" are set to carry out more applied positioning. (The execution order
and execution conditions are set in the "block start data" and "condition data".)
The following applied positioning controls can be carried out with "high-level positioning
control".

Block 1 start
(Normal start)
(Normal start)
With one start, executes the positioning data in a random block with the set order.
Condition start
Carries out condition judgment set in the "condition data" for the designated
positioning data, and then executes the "block start data".
• When the condition is established, the " block start data" is executed.
• When not established, that " block start data" is ignored, and the next point's " block
positioning data, and then executes the "block start data".
• When the condition is established, the " block start data" is executed.
• When not established, that " block start data" is ignored, and the next point's " block
start data" is executed.
Wait start
Carries out condition judgment set in the "condition data" for the designated
positioning data, and then executes the " block start data".
• When the condition is established, the " block start data" is executed.
• When not established, stops the control until the condition is established. (Waits.)

High-level positioning control sub functions
"High-level positioning control" uses the "positioning data" set with the "major
positioning control". Refer to Section 3.2.4 "Combination of QD75MH main
functions and sub functions" for details on sub functions that can be combined with
the major positioning control.
Note that the sub function Section 12.7.8 "Pre-reading start function" cannot be
used together with "high-level positioning control".

High-level positioning control from peripheral devices
"High-level positioning control" (start of the "block start data") can be executed
from GX Configurator-QP test mode.
Refer to GX Configurator-QP Operating Manual for details on starting of the "block
start data" from GX Configurator-QP.

Block 1:
"1 block" is defined as all the data continuing from the positioning data in which
"continuous positioning control" or "continuous path control" is set in the
operation pattern (

Besides the simultaneous start of "block start data" system, the "simultaneous
