Movement of elements
7392
Image and text elements can be moved on the display in a defined manner.
Element movement Description
Rotate Rotate the element around a defined pivot point
Indicate the angle of rotation

angle of rotation in [degree]

positive value = rotation clockwise

negative value = rotation anticlockwise
Shift Shifting of the element:

horizontal

vertical

only within the drawing area

max. until leaving the drawing area
Relative shifting of
• rectangle
• ellipse / circle
Each edge of the element can be shifted by a specified number of pixels via an
INT type variable:

basic position of the 4 edges = zero

new value shifts this edge by the specified value
Shift direction for value > 0:

horizontal edge down

vertical edge to the right
Shift direction for value < 0:

horizontal edge up

vertical edge to the left

Limitations for CAN in this device

FIFO ( F irst I n, F irst O ut) = Operating principle of the stack memory: The data packet that was
written into the stack memory first, will also be read first. Each identifier has such a buffer (queue).
Some Raw-CAN function elements enable transmitting and receiving of several messages in one PLC
cycle as the messages are temporarily stored in a FiFo:
- CAN_TX...,
→ Function elements: transmit RAW-CAN data
-
CAN_RX_ENH_FIFO
(
→ p.
62 )
-
CAN_RX_RANGE_FIFO
(
→ p.
66 )
The number of FIFo messages is limited. The following limitations of the devices are valid:
