Using RS Logix Software Make the following Ladder Logic:

A normally open, momentary push button, labelled PB1, is wired to a digital input of a PLC. This will be the Count push button.

A normally open momentary push button labelled PB2 is wired to another digital input of the PLC. This will be the Reset push button.

Three lamps, labelled LP1(i.e. a green lamp), LP2(i.e. an amber lamp) and LP3(i.e. a red lamp) are wired to digital outputs of the PLC.

In your Main program, each time PB1 is pressed a counter increments.

If the count value is greater than 0 but less than or equal to 10 then jump to Subroutine 1 (labelled GREEN). In Subroutine GREEN LP1 turns ON.

If the count value is greater than 10 but less than or equal to 15 then jump to Subroutine 2 (labelled AMBER). In Subroutine AMBER LP2 turns ON and LP1 turns OFF.

If the count value is greater than 15 then jump to Subroutine 3 (labelled RED). In Subroutine RED LP3 turns ON and LP2 turns OFF.

At first scan of the PLC program or if the Reset push button PB2 is pressed at any time: the counter should reset and LP1, LP2 and LP3 lamps all turn OFF.

NOTE: Your Lab solution must have one (1) Main ladder program and three (3) Subroutine ladder programs.
