　　1. Run the retrofitting numbers. Determine the cost-benefit of upgrading your existing equipment vs. buying new. Often the existing machine is sound and you can realize significant benefits with an intelligent control system upgrade. I regularly see throughput benefits of 30%-50% and savings in the hundreds of thousands of dollars after updating control hardware and implementing a better user interface. You can eliminate — virtually overnight — problems that you have lived with for years with a well-planned drive and control system upgrade. Retrofitting a machine will extend a proven asset’s life while improving production rates and reliability.
　　2. Involve the integrator early. Good partnerships build success. By involving the integrator early in the evaluation process, you have a better chance of getting the best solution for your production challenges. Good integrators look at the big picture and suggest cost-effective improvements to the entire production line that your team may not have realized were possible. Choose an integrator that you would like a long-term relationship with. They will look out for your best interests and help you achieve your budget targets through effective and experienced design efforts early in the project, instead of cost-cutting and features reductions when the money runs out.
　　3. Get the whole package. Make sure your integrator is providing the PLC/motion programmingwww.cechina.cn, HMI software design, drives, control hardware控制工程网版权所有, panel building, field acc
