217340-2

217340-2 is a standard that provides guidance for the application field and working principle of a communication transducer. This document defines the transducer\'s characteristics, its relationship to the electrical network, and the transducer\'s method of operation.Commonly referred to as a "2 wire transducer", the 217340-2 addresses input and output representation techniques for one-way communication between an electrical system and an adaptive electromechanical process. It is important to note that this document does not identify specific transducer technologies. Instead, the 217340-2 provides an overall framework for how the transducer should be applied, operated, and configured.The two main application fields for the 217340-2 are industrial process control and factory automation. In both cases, the transducer is typically used to measure and inform the process of physical properties like temperature, pressure, or flow. For example, in a chemical plant, a 217340-2 transducer may be used to measure the process chemical concentration and to provide feedback to an adaptive controller about the process’s status.At the heart of the 217340-2 is the concept of the transducer’s working principle. This principle dictates that the transducer must receive signals from an external source, convert them into a numerical value, and then transmit the resulting data back to the external source. The data is transmitted through a two-wire interface, which effectively breaks down the communication between the two sides into two distinct data streams.The first data stream involves the analog electrical signal the transducer receives from the external source. The 217340-2 requires that the transducer convert the incoming data into a digital format, which can then be more easily processed by the external source. This allows for easier debugging and analysis of the system\'s performance.The second data stream relates to the transducer’s ability to return its own numerical value back to the external source. This feature is important because it allows the external source to evaluate the transducer’s readings against the predetermined values set by the process engineer, and make adaptive adjustments to the process accordingly.Finally, the 217340-2 also outlines the general electrical wiring considerations associated with the transducer’s operation. According to the standard, all electrical connections must respect certain basic criteria in order to ensure that the transducer is properly communicating with the external source. This includes the presence of a local ground connection, proper shielding, and appropriate signal isolators.In summary, the standard 217340-2 provides the necessary information required to accurately understand the application field and working principle of a two-wire communication transducer. This document provides an effective framework for constructing, operating, and troubleshooting transducer-based systems, and is essential for successful integration of transducers into industrial and factory processes.
