![]() ![]() 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. ![]()
