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 ...

Are you looking for an easy touchscreen for your PLC? These HMI panels support many brands, connect in different ways, and ...

Old habits die hard. But change is inevitable. And in this case, if proponents are right, change is on the way in the form of an open PLC programming standard known as IEC 61131-3. Promulgated by the ...

A new family of PLC-controlled robots combines a SCARA robot with a PLC Server that allows direct programming of the robot from the Allen-Bradley family of PLCs, through a DF-1 serial connection. The ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...

One challenge faced by all control systems integrators (CSIs) is the prospect of testing their software before deployment. CSIs often work remotely, without having the actual equipment to manipulate, ...

The programmable logic controller (PLC) is an important component in most modern automation and process control systems today. It's also susceptible to lightning-induced transients. To verify the ...
