In part one of this series, we looked at the PLC’s internal architecture, briefly discussed Ladder Logic programming, Human-Machine Interfaces, advantages of the PLC’s ability to react consistently ...

Have you ever found yourself deep into a complex PLC program, struggling to decipher the logic behind it? Frustrating, right? Well, what if I told you there’s a powerful tool that can not only ...

In Part III of this series, we examined PLC programming methods (ladder logic and functional block diagram), and how the objects (coils and contacts) are system variables stored in the PLCs memory. We ...

Some common pitfalls in machine safety have to do with not wiring devices correctly. Many devices today can cover a range of safety levels, such as SIL 1 through SIL 3, but have different wiring ...

Though PLC (programmable logic controller) programming languages may not receive the attention that general computing programming languages, such as JavaScript, C#, or Python do, they remain critical ...
