Over the past two decades, Allen-Bradley MicroLogix controllers have been the backbone of many industrial automation applications. In favor of Compact Logix and Micro800, Rockwell Automation has phased out the MicroLogix product line; however, a large worldwide installed base continues to rely on MicroLogix controllers for daily operations. MicroLogix controllers automate countless OEM (Original Equipment Manufacturer) panels, commercial HVAC (Heating, Ventilation, and Air Conditioning) equipment, packaging lines, agricultural machines, and municipal water systems. The majority of MicroLogix installations are now over a decade old, with most of these controllers having been in continuous operation for 10 to 20 years. As such, to ensure operational continuity and reliability, their regular and effective maintenance is vital and no longer an option. Power fluctuations, component wear and degradation, harsh industrial environments, communication errors, and aging/obsolete electronics...
To provide reliable control for small automation systems, Rockwell Automation created the MicroLogix family of compact programmable logic controllers (PLCs).

If you work as a maintenance tech or plant engineer, you know the Allen-Bradley MicroLogix PLC. It’s everywhere in industrial automation, and for good reason; though, even the best equipment needs some care. Troubleshooting and regular maintenance help keep it in working condition. Here’s a guide that cuts through the jargon and turns those official specs into real-world advice you can actually use. The first and by far the most effective ‘line of defense’ against sudden system failures is good old proactive maintenance; after all, a well-maintained MicroLogix controller is just much less ‘likely’ to develop those catastrophic faults that cause so much production loss. All maintenance tasks must be carried out by a qualified technician familiar with the dangers of industrial control systems. Conduct pre-work maintenance when the power of a MicroLogix system is off and disconnected from all sources. Shop for MicroLogix 1000 Series PLCs and Accessories Here! The operating environment...
