PLCs Vs. Microcontrollers – Which Should I Use?

So, can a microcontroller be used in place of a PLC? The answer is in a very narrow set of circumstances, such as straightforward control requirements in a low duty environment, then the answer is yes. However, the differences above highlight that PLCs are designed for industrial and high-volume service applications that require safety, redundancy, ease of programming, and a host of other features that microcontrollers cannot provide.

What’s the Difference? – Variable Frequency Drive (VFD) vs. Soft Starter

VFDs and Soft starter have commonality in features however, VFDs offer more functions compared to Soft starters, particularly continuous modulation of Speed and Torque. Though VFDs may be capable of implementing more complex task, this doesn’t mean that VFDs are always the ideal option. Selection highly depends on the suitability and adherence to the selection factors mentioned in this article.

Hardware Comparison: Allen Bradley Servo Motor Selection Guide

Today’s motion control systems require motors that do many different things, such as precise positioning or controlled torque. Servo motors allow for better control of these conditions by allowing a high rpm spin at low torque yet slowing down and increasing torque as states require.   With position sensors, encoders, and gearing, microcontrollers can sense the actual…
