在过去的几年里,abb和其他自动化系统供应商已经开始减少这些串行的相互依赖性。首先,通过开发现场总线和无线仪器网络.数字通信技术的这些进步通过有效地完全消除对传统I/O硬件的需求,提高了系统的灵活性。添加到项目中的任何新的测量点或输出都必须以数字方式映射到更广泛的控制系统策略中,但这可以在项目的较晚阶段通过软件完成--这种方法比重新设计、重新排序和(或)重新安装多个新的硬件组件破坏性更小

In the past few years, ABB and other automation system suppliers have begun to reduce these serial interdependencies. Firstly, by developing fieldbuses and wireless instrument networks, these advancements in digital communication technology have effectively eliminated the need for traditional I/O hardware and improved system flexibility. Any new measurement points or outputs added to the project must be digitally mapped to a broader control system strategy, but this can be done later in the project through software - a method that is less disruptive than redesigning, reordering, and/or reinstalling multiple new hardware components
