摘要
针对西门子S7-400H PLC和温度巡检仪的冗余连接问题进行探讨,对该问题提出两种控制方案,并对两种控制方案的优缺点进行分析。对于新的控制方案,从连接方式、硬件配置、实现程序上分别作了详细介绍,并对新的方案在实际操作时遇到的问题进行分析,对遇到问题的解决方法做了具体阐述。通过实际应用和理论校验,证明了该方案的正确性和可行性。
The problem of redundancy connection between the Siemens S7- 400H PLC and temperature inspection instrument was discussed. Two control schemes were proposed for this problem and the advantage and disadvantage of the two control schemes were analyzed.For the new control scheme, the connection mode,hardware configuration,implementation procedures were described in detail,the new scheme in actual operation problem was analyzed and it expounds on the problem-solving method. Through practical application and theoretical verification, the correctness and feasibility of the scheme are proved.
