How the Single-Pair Ethernet Enables IIoT
New analysis explains why SPE is the future protocol for enabling the Industrial Internet of Things and migration to single Ethernet network technology.
Single-pair Ethernet (SPE) enables legacy industrial networks and building automation systems to migrate to single Ethernet network technology that delivers power, control and information to edge devices. It creates a seamless, plant-wide infrastructure that’s easy to maintain, and it provides greater reach and bandwidth for field device connectivity.
