Single F1 to control multi screen buttons ?
I have a EA3-S3ML-RN (non-touchscreen). Then I have 7 screen buttons, one for each days of week. How can I use F1 to select button then F2 to turn it ON or OFF ?

Have the PLC read the current screen number continuously.
Use F1 to go to screen Screen 99.
Use F2 to go to screen Screen 100.
When the PLC sees the screen number 99 it increments the day of the week control and sets the current screen back to where it was.
When the PLC sees the screen number 100 it inverts the selected day of the week control to turn on or off and sets the current screen back to where it was..
The current screen number configurations are on the menu PLC, PLC >> Panel.
This is new to me, I don't quite understands how it will select correct day of week. Are you thinking each day of week have its own screen ?
Do it in the PLC. Use an int as your day of the week and F1 as an increment button with the PLC resetting to 1 when incrementing from 7. Use F2 toggle the current selection active. How you do this in the PLC depends on the PLC used.
