3.3. Task shifting

 

While the HMI drawing screen is being executed, if a specific screen is loaded for the first time, it will take some time for the data to load. Accordingly, the screen will shift somewhat slowly. To shift the teaching pendant’s basic functions and the HMI function swiftly while HMI is being executed, the task shifting function can be used.

While HMI is being executed, if the teaching pendant’s CTRL + F1 keys are pressed, the teaching pendant’s screen with basic functions will be activated without executing HMI. During this state, the HMI screen will be reactivated by pressing the CTRL + F1 keys.
