Automation vendors have announced various services

To clarify the difference, let’s start by defining what I mean by services and products. By providing services, automation vendors engage with customers to perform labor and knowledge intensive tasks that may include system design, engineering services, system integration, preventative maintenance, remote operations, and other services. By providing products, automation vendors sell something to the customers, system integrators and engineering firms that they will apply to accomplish automation tasks in manufacturing and process environments.
