Normally, the ESC key moves focus out of the current menu and back to the previous menu, or in some cases it cancels an entry or change.

What keys on the LCD did you tell your program to use? It sounds like you used the ESC key as a program input key. Many PLCs with LCD displays allow defining the LCD display buttons ESC, OK, ^, v, <, and > as any program switch or pushbutton. It sounds like you need to read Chapter 5 in the MicroLogix 1100 User Manual, page 5-128, User Defined LCD Screen.
