Change is one of the constants on the factory floor. Whether it's manufacturing personnel figuring out better production techniques or designers tweaking devices, automation systems are always undergoing revision.
With the push towards custom manufacturing, that's not going to change. Keeping everyone up to date will become an even more critical part of the industrial control environment in the future.
Throughout the industry, suppliers of software development tools, manufacturing systems and software and even robot manufacturers are devising techniques that make sure changes get to all sites that need to know about them. And that's definitely a good thing.
