PLC Superseded by PC





Technology on the plant floor is fast appropriate the preferred way for achieving greater productivity with less overhead. PCs are currently common factory-wide at a lot of manufacturing sites, whether they are an automobiles worldwide provider or a local computer parts supplier.

In the control area, the proprietary hardware solutions use is being superseded by PC-based software solutions that allow a company to become more productive with economical technology of off-the-shelf. Companies are turning to these solutions of technology because they are more perceptive to their work force, therefore providing greater simplicity of use, fewer delays, and faster time to market. These companies require solutions that can develop with their organization as it fights in a more and more competitive world market.

This article discusses how PC-based control in particular is suitable the preferred “working smarter” solution for companies, whether they are manufacturing transmissions for automobiles, cataloging packages for overnight delivery worldwide, or creating automated storage and retrieval of items. The change from programmable logic controllers (PLCs) to technology of off-the-shelf personal computer (PC) calculating the manufacturing floor is being driven by the sizable business advantages that can be increased. Separately from the technology argue over protocols and data table formats, bits and bytes; there are important advantages that make the move to PC-based control an really forcing proposition for most manufacturing companies. Automation engineers and managers are cutting the design cycle of control system in half, making the system more maintainable and decreasing downtime with built-in diagnostics by shifting from PLC to PC-based control. This article discusses the advantages that are driving the revolution from ladder logic programming and PLCs to flowchart programming and PC-based control.

Manufacturing companies increase little advantage from the technical detail level needed to program a PLC to control their system manufacturing. Rather, they choose to focus on what can build them more competitive: improving their process by reducing downtime, decreasing design cycle time, and allowing continuous process improvement. Regardless of this, they observe their manufacturing controls group and engineering become tied up with the details of the protocols, bits, and bytes, required to configure and to program the PLC control systems. PLCs carry with them the 30-year-old complexities technology that is difficult to maintain.

Manufacturing managers and engineers have grieved the tools lack to allow them focus on improving their process over the last decade. They can’t give to waste their energy attempting or organization’s time to program complex PLC systems. The competitive pressure to cost down and increase throughput with less resource is driving the PC-based control revolution.
