Positions and position patterns

Function
After you have programmed the technology (cycle call), you must program the positions.
Several position patterns are available:
● Arbitrary positions
● Position on a line, on a grid or frame
● Position on a full or pitch circle
Programming a position pattern in ShopTurn
Several position patterns can be programmed in succession (up to 20 technologies and
position patterns in total). They are executed in the order in which you program them.

The number of positions that can be programmed in the one "Positions" step is limited to a
maximum of 400!
The programmed technologies and subsequently programmed positions are automatically
linked by the control.
