Introduction: Why the Micro850 Evolution Matters
In the world of industrial automation, change is constant. Programmable Logic Controllers (PLCs) like the Allen-Bradley Micro850 family are at the heart of countless machines and processes that keep industries running smoothly. Over time, technology advances, and so do the controllers powering our systems. Recently, many users have been hearing buzz about the Micro850 L50E — the new generation that’s set to replace the older LC50 model. But why does this matter to you? Whether you’re maintaining an existing system or planning an upgrade, understanding the evolution from LC50 to L50E helps you stay ahead. The new L50E controller doesn’t just bring a fresh name; it introduces meaningful improvements in communication speed, integration, and ongoing support, ensuring your automation projects can keep pace with today’s demands and future growth.
Side-by-Side at a Glance—LC50 and L50E in Brief
For those who want the essentials fast, here’s a quick snapshot. Both the Micro850 LC50 and L50E controllers belong to the same family — designed for machine and process control with scalable I/O options. They share similar internal memory sizes (around 10K program capacity) and support up to about 192 I/O points. However, the LC50 is officially discontinued, while the L50E is the current, actively supported model with enhanced networking capabilities. If you picture these controllers as siblings, the L50E is the younger, smarter one with updated communication skills and software compatibility while keeping the same strong foundation of I/O and memory.
Deep Dive #1: Communication—Ethernet and Protocol Power
One of the biggest leaps from LC50 to L50E lies beneath the surface in communication and data handling. The LC50 provides standard Ethernet connectivity that meets basic automation needs, including standard EtherNet/IP communication for simple device networking. In contrast, the L50E steps it up with faster Ethernet performance and enhanced support for Class 1 implicit messaging. What does this mean? The L50E can talk faster and more efficiently with Human-Machine Interfaces (HMIs), SCADA systems, and key industrial drives like the PowerFlex 520 and Kinetix 5100 series. It simplifies integration with these devices by using pre-configured tags, cutting down setup time. Furthermore, it broadens protocol options with expanded DF1 support, including half-duplex and radio modem communications. This makes the L50E more adaptable, especially in applications requiring real-time control and detailed diagnostics across networks.
Deep Dive #2: Firmware and Software—Tools and Compatibilities
Behind every reliable PLC is software that empowers it, and here the L50E clearly pulls ahead. The LC50 works smoothly with older Connected Components Workbench (CCW) versions, typically up to version 12 or 13. However, the L50E requires CCW 20.01 or later—which is aligned with Rockwell Automation’s push toward modern software ecosystems. This upgrade in development environment allows the L50E to unlock new features, improved diagnostics, and better programming tools. For engineers and system integrators, that means a fresher toolbox and longer firmware update lifecycles. It also means that migration from LC50 to L50E isn’t just a hardware swap — it’s a chance to leverage the latest in programming efficiency and controller functionality.
Deep Dive #3: Memory, I/O, and Practical Equivalence
Despite all the talk about advancements, it’s essential to understand where these controllers are fundamentally alike. Both the LC50 and L50E offer the same internal memory size — about 10K program steps — and can manage a similar number of I/O points, scaling up to around 192 with expansion modules. If your application’s core requirements focus solely on memory and I/O count, these two are practically equal. The real differences arise from communication capabilities, firmware support, and integration ease, not from raw processing power or slot count. So, for users worried about matching existing hardware specs exactly, the L50E delivers on that promise while bringing modernized features alongside.
Deep Dive #4: Modernization and Migration—From LC50 to L50E
All technology has its lifecycle, and the LC50 reached its official “end of life” in July 2023, meaning Rockwell Automation no longer supports it with firmware updates. Users relying on the LC50 are encouraged to migrate to the L50E to maintain compatibility with new software versions and benefit from enhancements. Migration is designed to be straightforward since the L50E acts as a drop-in replacement with familiar programming workflows. However, planning is key: engineers should test programs for compatibility, update development tools to the latest CCW, and consider any new features or communication protocols that can improve system performance. The migration isn’t just about future-proofing—it’s a chance to simplify network architecture and improve responsiveness with the next-generation controller.
Pro Tips and Gotchas—Real-World Migration Insights
Migrating from LC50 to L50E brings many benefits but isn’t without its surprises. One pro tip is to ensure your Connected Components Workbench software is fully updated before attempting migration, as older versions won’t support the L50E properly. Some users report slight differences in how L50E handles certain communication settings, so revisiting network configurations post-migration is wise. Also, the L50E supports new diagnostic tools that can uncover hidden issues in legacy programs, which might initially appear as challenges but ultimately improve system reliability. Real-world advice often highlights testing extensively in a simulation environment before swapping hardware in production. Staying connected to Rockwell user forums and support communities also helps anticipate and troubleshoot quirks during this transition.
