GE 129T2705G0001是一种现场总线，用于连接自动化系统的底层现场控制器和现场智能仪表设备。这种现场总线传输的是小批量数据，如检测信息、状态信息、控制信息等，虽然传输速率相对较低，但是实时性高。

此外，开放体系结构和OEM技术可以缩短开发周期并降低开发成本。其分布式结构将传统的1对1模拟信号传输方式变为1对N的数字信号传输方式，可以节省模拟信号传输过程中大量的A/D、D/A转换装置、布线安装成本和维护费用。因此，从总体上看，使用GE 8201-HI-IS现场总线的成本要低于使用传统DCS的成本。

It is a field bus used to connect the bottom level field controller of the automation system and the field intelligent instrument equipment. This field bus transmits small batches of data, such as detection information, status information, control information, etc. Although the transmission rate is relatively low, it has high real-time performance.

In addition, open architecture and OEM technology can shorten development cycles and reduce development costs. Its distributed structure transforms the traditional 1-to-1 analog signal transmission method into a 1-to-N digital signal transmission method, which can save a lot of A/D, D/A conversion devices, wiring installation costs, and maintenance costs during the analog signal transmission process. Therefore, overall, the cost of using the GE 8201-HI-IS fieldbus is lower than the cost of using traditional DCS.
