Substation Automation and Relay Communications
Published in Walter A. Elmore, Pilot Protective Relaying, 2018
With the increasing demand for power automation, a need arises to develop a system communication strategy that can handle high rates of data transfer. The ideal solution is to have the ability for data collection from various types of IEDs on a distributed network as well as a means to reliably control the substation equipment. Some high-speed communication interfaces embedded within the protective relay, which can also be called an IED, provide a means to communicate at rates of 1 million bits/s (1 Mbps) and higher. This type of system connects devices such as a programmable logic controller (PLC) and various types of IEDs, allowing plug-and-play automation solutions. A plug-and-play solution refers to a system in which components can easily be set up with minimal efforts and in some cases, the only setup required is to configure a device’s network address and make the physical connection to the network.
Configuration and Management of Networked Embedded Devices
Published in Richard Zurawski, Networked Embedded Systems, 2017
Plug and play describes a feature for the automatic integration of a newly connected device into a system without user intervention. While this feature works well for personal computers within an office environment, it is quite difficult to achieve this behavior for automation systems, since, without user intervention, the system would not be able to guess, what sensor data should be used and what actuator should be instrumented by a given device. Therefore, in the automation domain, the more correct term plug and participate should be used that describes the initial configuration and integration of a new device that can be automated. For example, after connecting a new sensor to a network, it could be automatically detected, given a local name, and assigned to a communication slot. The task of a human system integrator is then reduced to decide on the further processing and usage of the sensor data.

Plug and play describes a feature for automatic integration of a newly connected device into a system without user intervention. Although this feature works well for personal computers within an office environment, it is quite difficult to achieve this behavior for automation systems because without user intervention, the system would not be able to ascertain which sensor data should be used and which actuator should be instrumented by a given device. Therefore, in the automation domain, the more correct term plug and participate should be used, which describes the initial automatable configuration and integration of a new device. For example, after connecting a new sensor to a network, the sensor could be automatically detected, given a local name, and assigned to a communication slot. The task of a human system integrator is then reduced to deciding on further processing and usage of the sensor data.

As the plug-and-play operation was an important feature, the sensors communicate and draw power from the USB port of the connected device. The micro-controller communicates using a serial communication protocol (USB-CDC(ACM)). Since this is a standard USB protocol, a majority of the modern operating systems support this communication protocol without third party driver requirements. Tested on Windows, macOS, Android, ChromeOS, and Linux based OS, the plug-and-play operation works on virtually any device with a USB port.
