describe this resource and how it operates. The transducer is known by the name stored in the USER'S TRANSDUCER NAME TEDS. The physical communications media that connects the TIM to the NCAP is described by the PHY TEDS. The operation of a transducer channel starts with the reception of a trigger signal sent by the NCAP. The following sampling modes are supported: Trigger-Initiated; Free-running without pre-trigger; Free-running with pre-trigger; Free-running with pre-trigger without buffers enabled; Freerunning with pre-trigger and buffers enabled; Continuous sampling mode; and Immediate operation. The pre-trigger functionality is used in a transducer channel to allow the acquisition of a predefined number of samples before receiving the trigger to complete the sampling sequence. The free-running operation means that data acquisitions start as soon as the transducer channel enters the transducer Operating State. If the transducer channel owns buffers, then it can continue storing data after it reaches the end of the DataSet switching among them. The standard defines three different methods for reading this DataSet: only when commanded; streamed when the buffer is full; and streamed at fixed time intervals. In a smart city, the number of sensors and actuators is high, and therefore, the amount of data that the sensors/actuators transfer to the transmission channel is also high. To optimize the communication channel, a reduction in the amount of data is necessary so it will not congest the network. Furthermore, for all wireless sensors and transducers, there is a need to increase the life of the devices. Both the IEEE1451.001 standard and the IEEE1451.002 standard (under development) help overcome the two problems just described. Edge Information Processing with the IEEE 1451-001-2017 Using the IEEE 1451-001-2017 to Extract and Compute Information The representation of a signal by uniform sampling is not suitable for understanding and does not facilitate knowledge inference processes. Basically, it is due to one reason: it is unknown which samples carry information and which are redundant. All signals have some degree of redundancy. Redundancy generates degrees of freedom for interpretation and is necessary to detect errors in the extraction of Fig. 1.
