A Blank Canvas for Innovation
Combining the control and computing components of your machines in one place can help you reimagine your machines and how they solve customer challenges.
Just consider a few examples of how edge computing can help you create smarter, more secure and more autonomous machines.
Smarter: Edge computing can turn your machine into a protocol translator. In industries like oil and gas, for example, more companies are using the MQTT protocol to deliver data in their operations.
An in-controller computer can host the communications interface that translates Ethernet to MQTT. This can help end users make use of information on the protocol and make better decisions in their jobs.
More secure: Log-in passwords are notorious security risks. They can be seen, stolen or unwittingly shared. That’s why some companies are trying to forget passwords by finding an alternative.
Edge computing allows you to incorporate enhanced technologies into your assets. For example, you can easily add voice- or face-recognition software to create more secure access to your assets. This can prevent a machine from providing access or making changes unless it recognizes the person looking at it or their voice.
More autonomous: Industries like automotive production are looking for new ways to use mobile robotics to make their operations faster and more flexible.
Typically, if you want to make robotics move, you put them on a fixed track or wall. This gives them a specific pathway to move on and provides a foundation for their connection to their control and computing assets. But it also limits the robots to their set pathway.
Now, with edge computing, the control and computing assets can be stored on the robot. And with positioning and vision capabilities built into its computer, it can move and carry materials from one area of the shop floor to another while avoiding people and other assets.
Less is More
There are natural benefits of combining control and computing into one platform. The most obvious is the space savings. You no longer need to find a place for where your computing assets will go, whether it’s on the plant floor or in a server room.
Being able to access data at its source can also offer performance benefits. Operators can access real-time information to make more informed decisions. And your machine can perform better in time-sensitive applications – like when it relies on a camera or vision system to respond to changes in a matter of microseconds.
Then, there are the peace-of-mind benefits. You don’t have to worry, for example, if an in-controller computer was only built for the comfy confines of an office environment, like some PCs. And you worry less about the security of such a computer when it’s locked in a control cabinet and can’t be accessed by any passerby.
With edge computing, you can worry less about logistical IT considerations and, instead, focus on rethinking what’s possible in a smart machine: What questions can it answer faster? What new problems can it solve? How can it better protect operations?
