In the previous lesson I added a parallel shortcut path to the program to be able to run the motor in the momentary mode but this didn’t help and the motor was still running in the latched mode when I pressed the switch. Now let’s see how I can modify current PLC program to be able to run the motor in both momentary and latched modes using a single momentary switch.
In some industrial applications, you may need to count the number of products, cycles, the number of times a field device has been turned on and off, etc. Then you may need to use those numbers for another function within the PLC. For instance, you may need to count the number of bottles that are...
Now let’s assume that I need to use the value counted by the counter somewhere else in the program.
In an industrial process, there may be a conveyor belt with an electric motor that moves the manufactured products from the factory floor to the warehouse.
I’m going to write a simple PLC program for this system with the following conditions:
1) The motor is going to turn on when the start...
