I/O Architecture Evolution
You can gain significant advantages when evolving to more technical I/O architectures. When moving from Hardwired I/O to Distributed I/O you gain faster setup/tear-down and shorter cable runs and everything becomes moderately easier to troubleshoot. When transitioning from Distributed I/O to Networked I/O, you gain all of the benefits of Distributed I/O plus easier setup/repair in the hardware side and easier troubleshooting from diagnostic data in the software side. Finally if you move from Networked I/O to Decentralized I/O using IO-Link you gain more diagnostics as well as the ability to change parameters of smart devices on the fly.
