摘要：

There are three ways to replace a discontinued PLC with a new version. There are new PLCs that have conversion options to upgrade the CPU but utilise existing or new I/O cards. The wiring swing arms will work with the new component, so a complete rewire of the panel is unnecessary. The new rack can be prebuilt and tested before being installed in an existing control panel.
