The advantage of the foundation fieldbus is analyzed

Abstract: using the advantage of the foundation fieldbus analysis information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Foundation fieldbus as a living technology can stand out in a wide range of technology, has its unique advantages, but this advantage and commercial ads is not exactly the same, the advantages of field bus control system is not a simple surface is simplified. More flow meter manufacturers choose model price quote you are welcome to inquire, here is to use the advantage of the foundation fieldbus analysis for details. Foundation fieldbus as a living technology can stand out in a wide range of technology, has its unique advantages, but this advantage and commercial ads is not exactly the same, the advantages of field bus control system is not a simple surface now simplified construction, advanced control and reduce the daily production and maintenance costs, but a strong performance in the self-diagnosis function and equipment management function. Use of foundation fieldbus self-diagnosis function can strengthen equipment maintenance and management, make the equipment to be proactive maintenance, improve equipment management level; At the same time take advantage of fieldbus control system information can also be easily fieldbus devices for the whole life cycle management. Through the design, construction, debugging and routine maintenance experience, foundation fieldbus compared with the traditional control system has the following advantages: one, the control of has a broader view of the traditional DCS/PLC control system can only see the diagnostic information of control system, even with HART protocol of intelligent instrument can only see the limited information of equipment. Foundation fieldbus system can not only show the information within the host controller, also can show the information of fieldbus devices, fieldbus devices and host system as an organic whole, so the foundation fieldbus than traditional control system has a broader field of vision. The traditional control system ( DCS / PLC) Through the system since the diagnosis, judging the control system of power supply, the CPU, the l/O card if there is a fault alarm, but he could do nothing to the diagnosis of field devices, field device is passed to the control system of process variables, only for PV data is valid, The credibility of data) Can't judge. Due to the bottom of the fieldbus foundation fieldbus control system equipment and the host system as a whole, form a complete and transparent & other Information channel & throughout; , so all of the field bus network equipment information can be read by the host system, fieldbus devices communicate with the host system data PV value includes not only the process variables include the diagnosis information, any problems will promptly report to the police a fieldbus devices, operators can immediately to deal with alarm, reduce equipment supervision dead Angle, make the equipment for the factory in a controllable state. Second, advanced the self-diagnosis function of foundation fieldbus control system with advanced self-diagnosis function, the self-diagnosis function of field bus can speed up the equipment failure judgment of fieldbus, which make it easier for troubleshooting. In other words, find out the problems as early as possible can make plant outage time to zui short, avoid unnecessary stop time, it is for zui end user zui zui demand urgently important technology. Foundation fieldbus devices since the diagnostic coverage is very wide, it can be according to the experience of the manufacturers in the area of failure mode, use of additional sensors and electronic circuit and the self-diagnosis firmware algorithm for fault detection. For example, the field bus transmitter can detect the external sensor fault, such as thermocouple failure, it can also report environmental conditions, such as transmitter environment temperature is more than the limit temperature of equipment requirements, operators once found the alarm, inspection or maintenance will accordingly and ensure the zui better working condition of the fieldbus devices and & other Health & throughout; State. Fieldbus devices self-diagnosis zui big benefits does not tell us which machine is broken, but not bad now, tell us which device don't need to check; In other words, fieldbus devices provide diagnostic information can help us to make evaluation is & other; Equipment do not need to do now fault inspection & throughout; ； Equipment since the diagnosis can help us save a lot of work lost time. Foundation fieldbus devices using its powerful self-diagnosis function, eliminate the normal work of the equipment, the user can focus the goal of troubleshooting problems in minority of fieldbus devices, this can save a lot of manpower and material resources for the user. Fieldbus devices since the diagnosis of second benefit is based on the fault alarm equipment using advanced diagnostic tools to identify problematic instrument, based on the fieldbus devices provide diagnostic information can roughly determine the cause of the malfunction, determine to field work must carry the spare parts and tools. The module parameters of foundation fieldbus devices is overview of dynamic diagnosis fault zui ideal tool, it can through equipment management software to check the health status of equipment.
