Hi guys, I am trying to hide the “Power ON” button on my HMI when the cobot is powering up and only shows the button when the cobot has finished powering up. I wish to connect the button i/o to the cobot where once it’s finish powering up, the i/o will reflect as on but i cant seem to find that function. Are there any other solutions that i can use?

Is your HMI using a PLC or anything to communicate with the robot? If so, why not just use the robot states in the fieldbus connection to know when the arm is powered on fully? We did this with HMIs to have the text on the button reflect the current state of the arm similar to how UR does it on the initialization screen.
