Feature: SPE 6-part series
Article 2: What is necessary for facilities to implement single pair ethernet?
By Ruud Van Den Brink, product manager industrial communications and Manuel Ruter, senior principal engineer
Your SPE checklist Single Pair Ethernet (SPE) is growing in use in many industrial applications, from automated warehouses to smart factories. Industrial plants and manufacturing facilities interested in implementing SPE for their systems and connected devices may have questions about what equipment or technology they need to roll out this communication protocol. When making the decision about SPE, there are several factors to
consider. It is important to evaluate the existing connection technology and cables, as well as think about the types of semiconductors that will be used if SPE is installed.
Facilities should also consider: • What advantages can be gained? • Will SPE provide a return on investment (ROI) that makes the upgrade worthwhile?
• What is most important to the operation? Are weight or space savings a critical need in the facility, for example? Is increasing productivity a key goal?
In this third article of our six-part SPE series, learn about three
fundamental factors to consider when specifying a system and connections for SPE technology.
Factor 1: Connectivity Many industrial facilities already have a mix of sensor types on their equipment. Some sensors are equipped with Ethernet capabilities (smart sensors), while others are not. Take an inventory of the connected technology that is currently available in the facility. It will also be necessary to understand the proper power capabilities and strategies required for implementing SPE technology. In some facilities, the available power and connectivity are not enough to support the standards.
Factor 2: Cables It is also important to take an inventory of the cables available in the facility. In some cases, cables can be reused for SPE installation. Tis can cut down on the cost of SPE adoption and make the transition easier. Tere are many options available when choosing cables and other components. Cables are available in a range of lengths, from 10 meters to 1000 meters or more. Configurations include single- and double-ended, and available connector types include socket and plug.
Factor 3: Semiconductors Semiconductor types are available for point to point (PtP) or multi drop connections. Speed, range and possible failure modes should fit the needs of the application. Tink about which device is needed for which application for SPE installation.
Partnering with a solutions provider Tere are many options available to address different factors in facilities and in specific applications, especially with respect to what equipment is already in place. Component manufacturers, including TE Connectivity, can offer connectivity solutions, but in the end the customer must bring the application specifics to the equation and decide on which direction they want to go. Te solution should fit the application and not vice versa, so it is important to understand the standards of SPE and what is already available in the facility to support it.
In the next article of this six-part series, get answers to frequently asked questions about implementing SPE in an industrial application.
