Mustard. “Coupling together legacy systems with new IoT solutions exposes many vulnerabilities that can lead to cyber incidents.”
Moving to New Equipment May Be Cheaper
Adding new tech to existing equipment successfully required a full reconsideration of what needs to be accomplished and what’s the best strategy for doing it. ““The temptation is to go straight to the latest technical solution and work out how it can meet a requirement,” said Mustard. “In many cases, if the requirement is properly understood it may be possible to achieve it with fewer, less disruptive changes, to the existing environment.”
One of the advantages of IoT is that it’s relatively inexpensive compared with most machines and automation systems. Yet that low cost may be a siren song. “It’s easy to conclude that the latest IoT device is cheaper than upgrading legacy hardware if one looks only at unit costs. However, if one considers the changes required to the infrastructure, the additional training required for maintenance, and so on, then it may not be cheaper long-term,” said Mustard. “The best approach is to correctly define the business requirement, produce alternative solutions and properly cost the entire implementation and ongoing maintenance, then compare the two.”
EVERYTHING YOU NEED TO KNOW TO ADD NEW TECHNOLOGY TO EXISTING PLANT EQUIPMENT. When it comes to plant efficiency and effective connectivity, there are hurdles when plants choose to continue using their legacy equipment. Steve Mustard will cover this in detail in the session, Teaching Old Equipment New Tricks: Tips to Overcome Retrofitting Challenges at the Atlantic Design and Manufacturing show , which runs June 13-15 in NY.
