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 “rungs” or lines within the program.Īssigning 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 “OUT 0, 1, and 2”. The negative, black wire is connected to the PLC “COM 0 and 1” ports and connected to one side of each light. Then the black wire coming from the power cord is connected to “VAC L2” and “VAC DC5” on the PLC and “N” on the Power Supply.įrom the Power supply the positive, red, wire is connected to the “VAC DC0, 1, 2, 3, and 4” 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 “VAC L1” port, and to the “L” Port on the power supply. Always unplug the circuit, disable the circuit breaker and verify that the circuit has been de-energized.įor 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.
