Deploying Edge Computing Economically
Deploying edge computing on the shop floor can be imperative or strategically advantageous in some scenarios. A computing device capable of running software applications is typically necessary for implementation. Historically, implementers have opted for deploying separate computers for each use case, a costly approach that often restricts technology utilization.
Alternatives depend on the functions addressed in each use case to mitigate deployment costs. Utilizing existing computing resources on the shop floor is often overlooked but can significantly reduce or eliminate the need for additional hardware. A lot of equipment and many systems on the shop floor already incorporate computing elements with unused computing capacity. Collaborating with equipment suppliers to add incremental software functions can be a viable solution, circumventing the expense of adding new hardware.
Another cost-saving option involves selecting appropriate devices for edge computing functions. While industrial computers designed for shop floor installation are a common choice, their high cost may not be justified for functions requiring only a fraction of their capabilities. Alternative devices like Raspberry Pi and similar single-board computers offer cost-effective solutions, especially for communication adapter functions. These devices require installation in a protected environment and are readily available on shop floors.
Using Edge Computing To Protect Your Equipment
Network security is a paramount concern in digital manufacturing implementations, with a crucial tradeoff between security needs and associated costs. While securing external interfaces of shop floor networks has traditionally been prioritized, internal vulnerabilities pose significant threats.
Malware infiltration into manufacturing equipment, often unintentional, can have devastating consequences. Sources of malware include maintenance equipment, portable storage devices, and communication links, leading to unchecked spread throughout the network.
Deploying security devices throughout the shop floor is often perceived as expensive and with no immediate returns until a significant security event occurs, resulting in operational downtime and equipment damage. Managed network switches as edge computing devices offer a cost-effective solution to bolster shop floor security.
These switches enable effective segmentation to contain malware outbreaks, limit unauthorized communications, and provide network monitoring and configuration features. While managed switches may incur higher initial costs, their long-term benefits in preventing costly security incidents justify the investment.
Implementing edge computing solutions like managed switches safeguard equipment and fortifies network security, ensuring uninterrupted manufacturing operations.
Edge computing can deliver significant benefits in supporting data collection on the shop floor. Implementing these functions doesn’t always require significant expense – creativity can go a long way in achieving these benefits at minimal cost.
