Technical Specifications

Engineering Advantages

• Eliminate Communication Bottlenecks: The onboard 1Gbps Ethernet port facilitates massive data throughput for modern IIoT and analytics applications. It removes the latency typically associated with older bridge modules by processing network traffic directly on the CPU.

• Complex Logic Execution: This controller manages up to 32 simultaneous tasks with 1,000 programs each. This architecture allows engineers to segregate safety, motion, and standard control logic into high-priority execution threads without compromising scan times.

• Future-Proof Memory Capacity: With 40MB of user memory, the 1756-L85E handles large-scale code bases and extensive tag databases. It eliminates the need for frequent hardware upgrades when expanding production lines or adding complex HMI diagnostic screens.

• Simplified Programming Access: A front-facing USB 2.0 port provides a dedicated maintenance point. Field engineers connect directly for rapid firmware updates, programming uploads, and real-time troubleshooting without disturbing the primary Ethernet network.

FAQs

How does the 1756-L85E improve upon the previous 1756-L7 series?

The 1756-L85E increases processing speeds by up to 45% and includes a built-in Gigabit Ethernet port. Unlike the L7 series, which requires a separate 1756-EN2T or EN3TR module for networking, the L85E handles communications natively, saving valuable chassis slots.

Does this controller require a battery for memory retention?

No. The 1756-L85E utilizes energy storage technology and onboard non-volatile memory. This design eliminates the need for lithium batteries, reducing long-term maintenance costs and environmental disposal concerns.

Can I use this controller in an existing ControlLogix 1756 chassis?

Yes. The 1756-L85E fits into any standard ControlLogix chassis (such as the 1756-A7, A10, or A17). However, you must use a Series B or later power supply to ensure sufficient current across the backplane for the 5580 architecture.

What software version is required to program the 1756-L85E?

You must utilize Studio 5000 Logix Designer version 28 or higher. To leverage the full potential of the Gigabit Ethernet and advanced security features, we recommend using the latest available firmware and software version.
