- Primary choice

| | Cons | | :--- | :--- | | Built-in Ethernet: Allows easy integration with modern HMIs and SCADA systems. | Discontinued: Replaced by MicroLogix 1400; spare parts are becoming harder to source. | | LCD Display: Excellent for on-the-fly diagnostics without a PC. | Memory Limit: Only 4K user memory (instruction memory) is restrictive for complex programs. | | Modbus Support: Native support for Modbus RTU via the serial port simplifies integration with third-party devices (VFDs, sensors). | Battery Backup: The battery used to retain the program is located inside the unit, requiring careful replacement procedures. | | Reliability: Extremely low failure rate in industrial environments. | RSLogix 500: The software is legacy; Rockwell is pushing users toward the Connected Components Workbench (CCW) for newer Micro controllers. | | Expandability: The ability to add 1762 I/O modules makes it versatile. | High-Speed Counting: Limited to specific inputs and can be tricky to configure compared to modern high-speed counter modules. | micrologix 1100 software
