Feature: SPE 6-part series
Article 5: Different types of integration for single pair ethernet
By Ruud Van Den Brink, product manager industrial communications and Manuel Ruter, senior principal engineer
Brownfield and greenfield In the near future, one-cable Ethernet-based connectivity solutions can be deployed in smart factories to reach the next level of automation, which will help unlock new gains in manufacturing productivity and efficiency. This technological leap forward is possible thanks to efforts to establish a common standard for industrial Single Pair Ethernet (SPE) — a standard that finally makes it possible to bring Ethernet to the edge of the industrial network. When implementing SPE technology for connected devices
in industrial applications, there are two types of integration: brownfield and greenfield. Implementation differs based on which type of integration is used. In the fifth article in our six-part SPE series, learn more about the difference between these two types of SPE integration and how it impacts installation in a facility.

Brownfield integration This refers to an SPE network that is built to work with existing devices, equipment, or other resources. Some operations worry that they must completely remove their current solution or convert a large number of devices in order to install an SPE solution, and this may be holding them back from adopting the technology. But that is not the case. A facility may already have resources that can be used for SPE, including cables, connections and controls. This can reduce the level of investment and setup time for installation.
Greenfield integration This refers to an SPE project that is developed from scratch and not based on any existing systems, equipment, or infrastructure. A greenfield integration poses completely different questions than a brownfield integration since there
