Dear existing & future PLC software developers, I have published part 10 of my free PLC programming using TwinCAT 3 tutorial.
When designing and building a control system you will eventually want the control system to actuate something, be it a relay, a motor, a pneumatic system or maybe a complete 6-axis robot. To get feedback of the actuation, sensors are needed. In this part we will cover how we communicate with the environment using inputs and outputs.
hank you very much for your PLC program
