Don’t think it’s lazy—reusing effective control system strategy and programming can help you identify problems.
These technologies continue to evolve, making differences harder to distinguish. Here are some thoughts on what does what, and how to choose between a PLC and a PAC for your next application.
A few simple discussions with and demonstrations for your client at strategic times can prevent a world of problems and keep your project on track.
Using an element of object oriented programming can keep data organized and simplify writing code.
