Overview
The MicroLogix family was Allen-Bradley's small PLC platform from the late 1990s through the mid-2010s. While many models are now in end-of-life status, MicroLogix controllers remain in service in thousands of installed bases worldwide. Palm Parts Solution stocks refurbished and surplus MicroLogix CPUs and accessories for direct drop-in replacement.

Common Applications
- Legacy machine retrofits
- Small OEM machines (presses, saws, mixers)
- Building and water/wastewater applications
- Replacement of failed units in installed bases
Common Faults
- Battery low warning — replace 1747-BA or 2080-BAT before data loss
- RTC (real-time clock) drift — after battery exhausts
- Comms via 1761-CBL-PM02 dead — cable failure is common
- Channel 0 stuck — wrong baud rate, no DF1 handshake
- Discrete input intermittent — corrosion on field terminals
Troubleshooting Basics
- Connect via RSLogix 500 over DF1 / Ethernet.
- Read the Status File S2 for fault codes.
- Reset the fault and watch if it returns.
- Replace battery if low-battery bit is set.
- For comms failures, swap the 1761-CBL-PM02 cable.
