板卡应用：

DF PROFI II接口板卡可用作DP主站或DP从站。除了标准的PROFIBUS DP/DPV1服务，该板卡还提供一个看门狗功能，含物理PROFIBUS线路断开，符合主站class 1冗余思想。如果运作的PC系统出故障，一个无缝开关切换到一个冗余的备用系统。

找一款能同时模拟125个主站的板卡，类似woodhead的一个产品，有专门的软件可以实现的。主要是为了测试产品，woodhead不满足是因为他们只有PCI接口，而用户想用VNE或者PMC接口，“翻译过来客户的意思就是：“找一个能够模拟多个从站的DP板卡，通过一个物理的DP接口接到自己研发的产品上，模拟现场使用的多个从站一起工作的情况，从而测试自己研发的产品是否符合要求"那么这要求硬件上需要做的事情不会很多，可能就是要求板卡的IO数据处理能力较强。更多的工作其实应该是要在软件上完成的，我们的板卡如果是您自己开发应用程序的话，是可以完成的，即写一个应用程序:让它能模拟多个从站，然后设置不同的报文和发送间隔等，让它们模拟现场的情况一起发送给您的设备。这是可行的，推荐客户的是COMSOFT产品的DP PROFI II ，只是我们目前没有固定的标准软件，这个没有办法给您提供帮助。

电磁环境日益复杂，经实验室计量检定的高精度测量装置，受电磁干扰的影响，在工业现场不一定能够发挥其应有的精度特性，甚至不一定能够正常运行。

工业社会的快速发展使对测量的准确性、合理性和高效率提出了更高的要求，显而易见，融合着现代计算机技术、网络技术、通讯技术、自动化技术等的数字化设备信息和数据的处理分析能力更强、智能化、自动化程度更高，适应日益复杂的现场电磁环境的能力更强，它必将成为测量系统中*的核心构件。开发基于前端数字化的传感器/变送器和效率更高、分析运算能力更强的数字化测量二次设备也必然成为测试技术发展的主流方向。

Board application:

The DF PROFI II interface board can be used as a DP master or DP slave. In addition to the standard PROFIBUS DP/DPV1 service, the board also provides a watchdog feature with physical PROFIBUS line disconnection, in line with the master station class 1 redundancy idea. If the operating PC system fails, a seamless switch switches to a redundant backup system.

Find a board that simulates 125 main stations at the same time, similar to a woodhead product, and there is specialized software for that. Mainly to test the product, woodhead was not satisfied because they only had PCI interfaces and users wanted to use VNE or PMC interfaces." "Find a DP board that can simulate multiple slave stations, connect it to the products developed by yourself through a physical DP interface, simulate the situation of multiple slave stations used in the field working together, so as to test whether the products developed by yourself meet the requirements" Then this requires that the hardware needs to do not a lot of things, which may require the IO data processing ability of the board. More work should actually be done on the software, our board if you develop your own application, it can be completed, that is, write an application: let it simulate multiple slave stations, and then set different messages and sending intervals, so that they simulate the situation of the field together to send to your device. This is feasible. The DP PROFI II of COMSOFT is recommended to the customer, but we have no fixed standard software at present, so we can't help you.

The electromagnetic environment is becoming more and more complex, and the high-precision measuring device verified by laboratory measurement may not be able to play its due precision characteristics in the industrial field, or even may not be able to operate normally due to the influence of electromagnetic interference.

The rapid development of industrial society has put forward higher requirements for the accuracy, rationality and efficiency of measurement. Obviously, the digital equipment integrating modern computer technology, network technology, communication technology and automation technology has stronger processing and analysis ability of information and data, higher intelligence and automation degree, and stronger ability to adapt to the increasingly complex field electromagnetic environment. It will become the core component of the measurement system. The development of sensors/transmitters based on front-end digitization and digital measurement secondary equipment with higher efficiency and stronger analytical computing ability will inevitably become the mainstream direction of test technology development.
