在设备自动化升级过程中,置换I/O连接通常被看作是一种最基本的设备升级。设备内部I/O系统能够减少制造过程与控制系统之间因置换I/O连接而带来的不便。而且,在某些情况下,I/O系统甚至能够成为控制系统。
During a device automation upgrade, replacing I / O connections is often seen as a basic device upgrade. The device’s internal I / O system reduces the inconvenience of replacing I / O connections between the manufacturing process and the control system. And, in some cases, I / O systems can even become control systems.
