![]() ![]() NOTE: If you need to convert a SLC-500 or MicroLogix program to CompactLogix or ControlLogix, see our previous article here. Part of the migration to ControlLogix is to migrate the PLC-5 ladder code (RSLogix 5) to ControlLogix code (RSLogix/Studio 5000,) and this guide can help you through that process: Unless you are changing platforms, the most logical migration is to ControlLogix and there are both hardware and software migration tools to help you through the process with ease. ![]() If you have not created a migration plan, then it is probably time to do so. Click image for sourceĪs it will become more and more difficult to obtain parts if a failure does occur, it will become an increasing liability to keep the PLC-5 in control of critical production equipment. It says a lot about what a great product they have been. Even though they are no longer supported, thousands of them remain in operation. Fast forward thirty-one years later to 2017, Allen Bradley discontinued support of these processors after a long tenure of robust, solid performance. As I was entering kindergarten in 1986, Allen Bradley was releasing one of the first platforms that could be programmed by a personal computer, the PLC-5. ![]()
