ControlLogix series 6 controllers

In 2002, the bulletin 1756 ControlLogix L6 (Logix556x) processor was released with a more powerful processor and more memory, and the CompactFlash nonvolatile memory card was added to the entire lineup.

ControlLogix represents a common control engine with a common development environment and tight integration between the programming software, controller, and I/O modules. This close integration greatly reduces automation engineering development time and cost.
