The Allen-Bradley 1771 Series is a discontinued family of programmable logic controllers (PLCs) that were manufactured by Rockwell Automation. The 1771 Series PLCs were introduced in the 1980s and were widely used in industrial applications for many years. However, they have been discontinued In recent years due to advances in PLC technology, PLC-5 Control System has been replaced by ControlLogix Control Systems.

The 1771 Series PLCs were powered by the 1771-1 PLC controller, which was a 16-bit processor. The 1771-1 PLC controller was capable of handling a wide range of control tasks, including ladder logic, function block diagrams, and structured text programming.

The 1771 Series PLCs were available in a variety of configurations, including rack-based, modular, and embedded PLCs. This made it easy to select the right PLC for the specific needs of an application.

The 1771 Series PLCs were programmed using the RSLogix 5 software application. RSLogix 5 is a powerful and user-friendly software application that allows users to create, edit, and debug PLC programs. It also offers a variety of built-in functions, such as ladder logic, function block diagrams, and structured text programming.
