To design a highly dynamic HMI, it can be very useful in certain scenarios to be able to import PLC variables at runtime without necessarily doing so at design time. Such operations are usually done using a file exported by a PLC programming software at design time.
UNIQO HMI is now able to obtain the list of variables for TwinCAT and Siemens TIA Profinet protocols at runtime; filters can be applied (for example, by name) to these variables to select the necessary ones for the application.
Finally, a retentivity storage can be very useful to maintain the imported variables after the next restart so they aren’t imported each time.View all news
