10 HIGH-LEVEL POSITIONING CONTROL
10.3.3 Condition start
In a "condition start", the "condition data" conditional judgment designated in "
Da.14
Parameter" is carried out for the positioning data set in "
Da.12
Start data No.". If the
conditions have been established, the " block start data" set in "1: condition start" is
executed. If the conditions have not been established, that " block start data" will be
ignored, and the "block start data" of the next point will be executed.
Section [2] shows a control example where the " block start data" and "positioning
data" are set as shown in section [1].
