PC vs. PLC: Key Factors in Comparing Control Options

Overview:

One of the most crucial decisions in the initial design phase of a machine is the selection of the control system. For years, the PLC has been leading the way for advances in machine automation control. From small controls used in the automotive industry to large-scale controllers running entire factories, the PLC was the primary controller of choice.

However, from the early 90s to present day, the PC has been successfully working its way into those markets as processor speed and range continue to increase and the cost of those components continues to decrease. The number of applications utilizing a PC is on the rise, causing an accelerated development that blurs the line between the two technologies.

This white paper discusses what factors to consider when deciding whether to choose a PLC or PC.
