Using an output address as an input in a program

In the previous chapter, we learned that an output address can be used as an input address (NC or NO contact) in the rules for ladder diagram programming.

The following example shows an output address (Q0.2) being used for an input. You can write the program in network 4 and simulate the program to see how it works.

Figure 9.31 – Output address (Q0.2) used for a normally open (NO) contact at the input

Figure 9.31 – Output address (Q0.2) used for a normally open (NO) contact at the input

The wiring diagram for the program is as follows:

Figure 9.32 – Wiring diagram to implement a program using an output address for input

Figure 9.32 – Wiring diagram to implement a program using an output address for input

Let’s say a pilot lamp (PL3) is connected to Q0.3, as shown in the preceding diagram.

Anytime Q0.2 is ON, the normally open contact with the address Q0.2 will be closed since the coil with the address Q0.2 is energized and PL3 connected to Q0.3 will be ON.

If we edit the program by replacing the normally open contact...
