• OPC UA server
• Global Security Certificate Manager
• Cycle times, e.g., maximum cycle time
• Properties for the operation of the display
• System and clock memory
• Protection level for access protection with assigned password parameter
• Time and day settings (daylight saving/standard). For additional information, refer to the
following FAQ on the Internet
