摘要
HART协议是由模拟系统向数字系统转变过程中唯一向后兼容的智能仪表解决方案，它在兼顾现场总线优点的同时。保留了对现有4。20In系统的兼容性，具有较高的应用价值。介绍了一种基于HART协议的CDS-3151GP智能压力变送器的工作原理，论述了如何应用HK-HART232组态／调试系统对CDS-3151GP智能压力变送器进行组态、标定、诊断和检测。
The HART protocol provides a uniquely backward compatible solution for smart instrument in the process of changing horn analog systems to digital systems. It has the merits of fieldbus as well as remaining the compatibility of existing 4 ～ 20 mA systems and has preferable application values, Introduced working principle of CDS- 3151GP intelligent pressure transmitter based on HART protocol and specifies the methods of configuration, demarcation,diagnosis and detection for the CDS- 3151GP intelligent pressure transmitter using the HK- HART232 configuration/debug systems.
