The PLC is very much alive and well, with a long life ahead. However, this industrial workhorse has morphed in numerous ways to expand its appeal. Automation suppliers continue to improve the PLC to serve
PAC Provides Lower Lifecycle Costs
Craig Resnick, ARC's Research Director of Manufacturing Advisory Ser-vices said, "PACs address the integration issues confronting OEMs and end users by extending the domain expertise of automation systems, resulting in increased return on assets, reduced lifecycle costs, and a lower total cost of ownership for manufacturers." Machine builders and OEMs want fewer components in their solution and ones that contain multiple-discipline development and functionality. The demand for more flexible and modular machines and processes permeates the market. The PAC's multi-domain functionality includes logic, motion, drives, and process control on a single platform. It can also easily exchange data with networked multi-vendor systems.
"A PAC is flexible and configurable, so users can customize and optimize it to meet their particular requirements for controlling and automating both machines and plants, " according to Craig Resnick. All parts of the PAC system are designed to maximize software and hardware integration. There should be one programming and engineering tool for the complete system. This capability includes transparent access for all parameters and functions within the entire system, combining PLC, remote I/O, motion control, drives, PID control, user guidance, visualization and data handling, along with a maximum integration level to the enterprise though the use of Ethernet TCP/IP, Internet, and IT standards.
How Will PACs Affect the Market?
PACs are creating additional opportunities, rather than displacing traditional configurations. The integrated, common development environment lowers project development and implementation costs. This will expand the number of financially justifiable projects and the available market opportunities. Use of PACs will continue to shift the emphasis toward open communication standards and software integration, with less focus on the hardware. Users will become more focused on the total system performance rather than the hardware selection. PACs will address user concerns as to how to better monitor and control the real-world devices that are connected to the hardware. This keeps the suppliers of PACs thinking more about system optimization and performance and less about market differentiators at the hardware and component level.
Today, manufacturers are increasingly turning to suppliers for services ranging from consulting to full turn-key projects. Users are refocusing their energies on core competencies and relegating their automation and control integration functions to the automation providers. This creates a greater need for service and support offerings that will complement and utilize the multi-functional capabilities of PACs. An example of this could be Web-based monitoring and maintenance through a PAC for logic control, position control, cam-positioning, and two-axis motion control. Operators can access the supplier Web site to allow technicians to diagnose and trouble-shoot problems directly from the plant floor.
