The first timer is the time duration that the red light will remain on, the second timer corresponds to the yellow light and the third to the green light. On the fourth rung, assign the switches to T4:0/DN and T4:2/TT. On the third rung, assign the switches to T4:2/DN and T4:1/TT. On the third and fourth rungs, insert one вЂњbranchвЂќ onto the input of each, with one вЂњExamine if ClosedвЂќ switches on each line created by them. In the other two lines created by the branches, insert one вЂњExamine if ClosedвЂќ switch onto each, and assign one to T4:1/DN and the other to T4:0/TT. On the first rung, insert two вЂњbranchesвЂќ to the left side of the rung, and insert one вЂњExamine if OpenвЂќ, assigned to B3:0/0 into one of those branches. On the three remaining rungs, insert a вЂњTimer OnвЂќ timer on the right side of each and assign them in descending order as T4:0, T4:1, and T4:2.

On the second rung from the top, insert one вЂњOutput EnergizeвЂќ to the right side of the rung and designate it to B3:0/0. In descending order, designate the вЂњOutput EnergizesвЂќ to O:0/0, O:0/1, and O:0/2, and the вЂњExamine if ClosedвЂќ switches to T4:0/TT, T4:1/TT and T4:2/TT. On the bottom three rungs, insert one вЂњExamine if ClosedвЂќ switch on the left side and one вЂњOutput EnergizeвЂќ on the right side of each of the rungs. Their menus can be opened by double-clicking the name in the drop-down menu on the left side of the screen. O addresses correspond to outputs, B addresses to Binary, and T addresses to Timer. To Program the PLC, begin by creating 7 вЂњrungsвЂќ or lines within the program.ДЄssigning the addresses can be done with the same drag and drop method. The Binary and Output bit addresses for this program are all in the top line of the table, starting at 0 on the right side. DN will be enabled when the timer reaches its preset time. In the timer table, TT refers to 'Timer Timing,' meaning the bit will be enabled when the timer is timing. The bottom three pictures show the Timer, Output and Binary tables, and where they can be located in the menu on the left side of the screen.

The second command set, directly below the first picture is the timer set, the only command used from this set in this program will be the 'TON' or Timer On. The top picture shows the basic commands, the only ones used from this set are the first five. RSLogix uses 'Drag and Drop' for placement of its commands and addresses, meaning to insert the command or address, simply click and drag it from the menu to the desired location, then drop it. The other side of each light is then connected to the PLC ports вЂњOUT 0, 1, and 2вЂќ. The negative, black wire is connected to the PLC вЂњCOM 0 and 1вЂќ ports and connected to one side of each light. Then the black wire coming from the power cord is connected to вЂњVAC L2вЂќ and вЂњVAC DC5вЂќ on the PLC and вЂњNвЂќ on the Power Supply.ДЇrom the Power supply the positive, red, wire is connected to the вЂњVAC DC0, 1, 2, 3, and 4вЂќ ports on the PLC. To begin, start by connecting the PLC to power with L1, the white wire coming out of the power cord into the вЂњVAC L1вЂќ port, and to the вЂњLвЂќ Port on the power supply.

Always unplug the circuit, disable the circuit breaker and verify that the circuit has been de-energized.ДЇor this application, the full wiring shown in the picture above is not required, only the wiring described below. CAUTION: Never work on a live circuit, the AC line of the power is connected directly to the wall outlet and 110V, enough to kill a human or cause severe electrical burns including damage to internal organs.
