Wait start

In a "wait 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" is
executed. If the conditions have not been established, the control stops (waits) until the conditions are established.
Section (2) shows a control example where the " block start data" and "positioning data" are set as shown in section
(1).
