Altivar inverter and using the display terminal to access simply start

[Connorsph]

Hi there, trying to use the display terminal to access simply start to adjust max frequency from 60hz to 45hz. 
I have plugged display into the HMI port and have adjusted one machine this morning. I have 3 more to do but I’m trying to access the other 3 altivar machines the simply start menu doesn’t show up? Anyone can help?

kind regards

Connor
