近年来,随着西门子PLC系统在油田的生产过程中应用的日益增多,对其时间不能准确同步问题的研究也就显得更加重要,对该问题的研究也急需深入。就以油田生产中应用较为普遍的西门子S7-300系列为例,从PLC系统应用中日期与时钟编程的特殊性入手,通过对PLC时钟功能指令进行分析,实现可随时对西门子PLC系统进行时间同步,先找出其中存在的问题并分析原因,再给出一系列可行的改进措施。

In recent years, with the increasing application of Siemens PLC system in the oilfield production process, the research on the problem that the time can not be accurately synchronized becomes more and more important. Therefore, the research on this issue urgently needs further study. Take the Siemens S7-300 series which is more common in oilfield production as an example. Starting from the particularity of date and clock programming in the application of PLC system, through the analysis of PLC clock function instructions, the Siemens PLC system can be time synchronized at any time , First find out the existing problems and analyze the reasons, then give a series of feasible improvement measures.
