FANG Yan-jun, LIU Jing-yu. Research and design of temperature collection device based on PROFIBUS-DP[J]. 2007, (10): 84-86. DOI: 10.13873/j.1000-97872007.10.028.
The characters and the multi channels temperature collection circuits of thermistor and thermocouple are analyzed
the function
the structure and the designing method of the PROFIBUS-DP slaves are researchs.The intelligent multi resistance thermometer and thermocouple collection DP slave devices based on SPC3 are designed respectively.The testing confirms that the intelligent DP slave temperature collection devices have good performance on their communication with DP master and their temperature collection’s precision.
