Additional Installation Tips
7.8.3 RestrictionsandRecommendations
• The maximum supported bit rate depends on bus load, bus topology, number
of nodes, bus termination, propagation delay of each CAN node and the bus
length.
• Do not connect more than 32 nodes to one CAN network without using a
repeater.
• If the bus length exceeds about 200 m, it is recommended to use CAN nodes
with built-in galvanic isolation.
• If the bus length exceeds 1000 m, a CAN bus repeater should be used.
• For additional information refer to the driver documentation for Fre e CAN
and Can Open in the iX Developer software.
7.9 ImageSticking
When utilizing TFT LCD HMI panels in applications where a fixed or partially
fixed image remains displayed on the screen for extended periods of time,
users may experience a phenomenon referred to by the LCD industry as Image
Sticking. Image sticking, sometimes also called “image retention” or “ghosting, is a
phenomenon where a faint outline of a previously displayed image remains visible
on the screen when the image is changed.
Image sticking can be caused by:
• Staticimages
• No screensaver
• Sharp contrast transition (e.g. black/white)
• High ambient temperatures
How Image sticking can be avoided or reduced:
• Use the screensaver functionality (see SW manual).
• Changing constantly between static and dynamic images.
• Avoid excessive brightness differences between foreground and background
elements.
• Use colors with similar brightness.
• Use complementary colors in follow-up images.
