7.8.3. Restrictions and Recommendations
• 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 FreeCAN and Can Open in the iX
Developer software.
7.9. USB Flash Drive
The USB port, or ports, are of 2.0 standard and support FAT16, FAT32 and exFAT file systems for USB
flash drives (option, sold separately).
Size limitations for file systems:
• FAT16: up to 2 GB
• FAT32: up to 32 GB
• exFAT: up to 2 TB
7.10. Image Sticking
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:
• Static images
• 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.
