Ladder Diagrams and Logic: Simplifying PLC Programming
Ladder Logic is like the DNA of industrial control within programmable logic controllers (PLCs). At its heart, it's a visual language with three key elements: contacts, coils, and blocks. Contacts: Think of contacts as the messengers. They show the PLC's inputs, such as signals from switches or sensors.
