BENTLY 60M100-00 通过使用现场总线，用户可以大量减少现场接线，用单个现场仪表可实现多变量通信，不同制造厂生产的装置间可以完全互操作，增加现场一级的控制功能，系统集成大大简化，并且维护十分简便。比较的前题是DCS系统与典型的、理想的FCS系统进行比较。为什么要做如此的假设。做为DCS系统发展到今天，开发初期提出的技术要求却已满足并得到了完善，目前的状况是进一步提高，因此也就不存在典型、理想的说法。而作为FCS系统，90年代刚进入实用化，作为开发初期的技术要求：兼容开放，双向数字通信、数字智能现场装置、高速总线等，目前还不理想有待完善。这种状态与现场总线国际标准的制定不能说没有关系。完全可利用它进行PLC自身工作的监控，或对控制对象进行监控。过去的十多年，各总线组织都忙于制定标准，开发产品，占领更多的市场，目的就是要挤身于国际标准，合法的占领更大的市场。BENTLY 60M100-00现在有关国际标准的争战已告一段落，各大公司组织都已意识到，要真正占领市场，就得完善系统及相关产品。我们可以做这样的预测，不久的将来，完善的现场总线系统及相关产品必须成为世界现场总线技术的主流。BENTLY 60M100-00
The topic of comparison is to compare DCS system with typical and ideal FCS system. Why do we make such assumptions. As the DCS system has developed to this day, the technical requirements put forward at the initial stage of development have been met and improved. The current situation is further improved, so there is no typical and ideal statement. As an FCS system, it has just been put into practice in the 1990s. As a technical requirement at the initial stage of development: compatibility and openness, two-way digital communication, digital intelligent field devices, high-speed bus, etc., it is still not ideal and needs to be improved. This state cannot be said to have nothing to do with the formulation of international standards for fieldbus. In the past ten years, all bus organizations have been busy formulating standards, developing products, and occupying more markets.
