Some questions about learning PLC*
Thread Content
I’m a complete beginner when it comes to PLCs, and I’d like to create a simple PLC-based control system. I would appreciate any guidance from those who are more experienced: I just want to build a PLC system for controlling the start and stop of a motor, as well as for monitoring the liquid heating temperature and providing alerts when the level reaches a certain threshold; the system should also trigger an automatic shutdown if the temperature gets too high. Could you tell me where I should start learning? The more practical, the better. Thank you in advance!
