ControlLogix 5580 vs 5570

May 29, 2025

Allen-Bradley ControlLogix controllers are engineered for applications that demand scalability and high I/O capacity. Installed into available slots within a ControlLogix I/O chassis, multiple controllers can coexist in a single chassis, offering unparalleled flexibility and processing power. This guide compares two flagship series: the ControlLogix 5580 and ControlLogix 5570, highlighting key similarities, differences, and application insights.

Programming Software Compatibility

  • Both series utilize Studio 5000 Logix Designer.

  • 5580: Requires version 28.00 or later.

  • 5570: Supports version 21 or later.

  • Both allow automatic or manual configuration loading from nonvolatile memory.

Memory Capacity

  • 5580: 3 MB to 40 MB (e.g., 1756-L81E to 1756-L85E).

  • 5570: 4 MB to 32 MB.

  • I/O Memory: Only 5570 includes dedicated I/O memory (0.98 MB).

  • Both support SD cards for nonvolatile memory storage and recovery.

I/O Support

  • 5580: Supports 5069 Compact I/O modules.

  • 5570: Does not support 5069 Compact I/O.

Ethernet Capabilities

  • 5580:

    • Embedded Ethernet port: 10/100/1000 Mbps.

    • Up to 128,000 pps (I/O), 2,000 msgs/sec (explicit).

  • 5570:

    • No embedded Ethernet.

    • Requires external communication modules.

Integrated Motion Control

  • 5580: Up to 256 axes; only supports EtherNet/IP (SERCOS and analog motion with v31+).

  • 5570: Up to 128 axes; supports SERCOS, EtherNet/IP, and analog.

  • Motion rate: 5580 = 19 axes/ms (backplane), 32 axes/ms (EtherNet/IP); 5570 = 8 axes/ms (backplane).

Communication Interfaces

  • Built-in ports:

    • 5580: USB + Embedded Ethernet.

    • 5570: USB only.

  • Supported networks:

    • Both: EtherNet/IP, ControlNet, DeviceNet, DH+, Remote I/O, SynchLink.

  • Connections:

    • 5580: Embedded Ethernet + modules; supports 100–300 nodes depending on model.

    • 5570: Up to 500 controller connections; limited to module-based communication.

Redundancy Support

  • 5570: Fully supports redundancy.

  • 5580: Supports redundancy with Studio 5000 v33+.

Throughput Architecture

  • 5580: Parallel application and communication threads (multi-core).

  • 5570: Single-core operation (shared for both functions).

Electrical & Physical Specs

  • Power Draw:

    • 5580: 5.0 mA @ 1.2V, 1.20 A @ 5.1V, 6.2 W, 21.2 BTU/hr.

    • 5570: 5.0 mA @ 1.2V, 0.8 A @ 5.1V, 2.5 W, 8.5 BTU/hr.

  • Weight & Dimensions:

    • 5580: 0.394 kg, 5.5 x 5.717 x 1.36 in.

    • 5570: 0.25 kg, 5.627 x 5.717 x 1.36 in.

Environmental Ratings

  • Operating temp: 0–60°C (both).

  • Non-op temp: -40 to 85°C (both).

  • 5580 only: Advanced immunity to EFT/B, surge, and RF per IEC standards.

Indicators & Reset

  • Both: 4-character display, RUN/FORCE/SD/OK LEDs.

  • 5580 only: Ethernet status LEDs, Reset button for staged controller memory clearing.

Summary The ControlLogix 5580 series is the future forward choice with embedded Gigabit Ethernet, 5069 I/O support, higher memory, and motion capabilities. The 5570 series, while still powerful, lacks embedded Ethernet and is best suited for systems requiring legacy communication methods or full redundancy.
