13.12 Moving Shape
The Moving Shape tool is used to place an object in a window at a location specified by the PLC. The state and the
absolute location of the shape in the window depend on the current values of three continuous PLC registers.
Typically, the first register controls the state of the object the second the horizontal position (X), and the third the
vertical position (Y).

Moving Shape Design Tips:
1. Use a moving shape as a pen for a trend chart. Set it so that the pen shape corresponds to the trend chart input.
Change the state of the pen shape to change from green to red when a high or low limit is exceeded.
2. Use a moving shape object as a pointer to a setpoint on a bargraph. Set it so that it corresponds to the one of the
variable set points. As the operator changes the setpoint, the pointer moves to a new position.
X & Y position is
controlled by PLC
