The time and cost of integration is significant over the life of a system and should be examined as part of the analysis.

This can be accomplished with a demonstration system provided by vendors, including controller hardware. This investment upfront can save a large amount of money and lost production time over the life of a system. Selecting the right system for your operations requires complex analysis, with a number of considerations, based on production processes, in-house capabilities, and other factors. I have never understood how engineers that would never buy a new automobile without looking under the hood and taking test drives will buy an automation system based on vendor demonstrations and PowerPoint presentations. ![]()
