To put it simply, a fieldbus is the underlying data communication network in the field of automation. It mainly solves the digital communication between field devices such as intelligent instruments, controllers, and actuators in industrial sites, as well as the information transmission between these field control equipment and advanced control systems. The fieldbus control system consists of three parts: measurement system, control system and management system. In this system, the instrument adopts a digital signal output, which makes the measurement data of the instrument have extreme capabilities and other functions. Hardware structures such as instrumentation are the main support systems for completing fieldbus tasks. The hardware system of the fieldbus is mainly related instruments such as sensors. Fieldbus instrumentation advantages 1. Digitality The fieldbus communication method is different from the analog communication and hybrid communication methods, and it is a completely digital communication signal. From instrumentation such as field transmitters and sensors to the final control valve, the signal remains digital. In this way, the hardware structure of the instrument is simpler, and its resolution, measurement speed and stability are at a high performance. 2. High precision Fieldbuses eliminate errors in data transmission in analog communications. In this communication method, there is no D/A and A/D conversion circuit, so there is no corresponding error. The accuracy of the instrumentation is guaranteed. 3. Strong anti-interference Since the value of the analog signal can change wirelessly, noise and distortion of the signal are unavoidable in transmission. The instrumentation signal for the fieldbus is only a valid 0 or 1, and it is difficult to distort the general noise. Therefore, compared with analog signals, the instrument has strong anti-interference and anti-distortion capabilities.
