PLC Screens
The PL screen is a main screen of the TReX-460 that displays the currently configured ladders
in groups of six lines. Further lines can be reached by pressing the DOWN button on the front
of the device. Each line is displayed with it’s corresponding inputs and their current states as
well as the output of the line and it’s current state.
When an input is displayed as black text on a white background , it is open (or inactive) . If
displayed as white text on a black background , it is closed (or active) . Like a standard
ladder logic display, normally closed inputs are preceded by a slash character (“/”).
The number displayed in the top right corner indicates which page is currently displayed, with
the first six lines displayed on page one and following lines displayed on subsequent pages.
The order of ladder program execution starts at the top of page 1 and proceeds downwards
through subsequent pages. Each rung supports up to three inputs.
The “P” top left icon indicates that the PLC program is running and outputs are being
controlled.
