START 3 Positioning data record address irrelevant
Positioning data record 4 is executed
START 4 Positioning data record address irrelevant
Positioning data record 4 is executed, because repetition
counter = 2
START 5 Positioning data record address irrelevant
Positioning data record 5 is executed
A sequential position procedure can be terminated with a repetition number = 0.
For this purpose the repetition number 0 must stand for the data record following
after the last valid positioning data record.
When Compax3 encounters a data record with the repetition number 0, a new
positioning data record address is read in and the corresponding positioning data
record is executed immediately.

Column 1: Positioning data record address
Column 2: Repetition counter
START 1 to START 5 see Example 1
Action Behaviour
START 6
Repetition counter = 0
⇒
Positioning data record address is read in
Positioning data record 7 is executed
START 7 Positioning data record address irrelevant
Positioning data record 7 is executed, because repetition
counter = 2
On a START edge (X12/7=24VDC), the positioning data record addressed via the
inputs I3 to I6 (I7) is always executed.
Therefore the desired positioning data record must be addressed before each
START.
