My name is Shawn Tierney from The Automation Blog, and I love sharing what I've learned about automation products with others. I spent my first twenty five years in the automation business working as a Rockwell Automation Distributor Specialist helping electricians, technicians, and controls engineers implement automation solutions using Allen-Bradley PLCs, PACs, and HMIs, as well as Rockwell Software SCADA and MES products.

And I'm also the author of the internet's most popular independent automation blog, The Automation Blog dot com, where I enjoy discussing automation products and challenges with people from around the world.
