Information About 1756-L63

The 1756-L63 belongs to the ControlLogix 5560 controller family and is housed in a multi-slot chassis alongside communication modules, power supplies, and I/O modules. Its architecture supports up to 32 tasks and 100 programs per task, enabling advanced process structuring and event-driven execution. The controller can interface with a wide range of network technologies—including EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, and SynchLink—via plug-in communication adapters. Featuring full redundancy support, integrated motion via SERCOS or Ethernet/IP, battery-backed RAM, and optional CompactFlash storage, the 1756-L63 is well suited for high-availability and high-performance automation environments.

Key Features

  • High-Memory PAC: Includes 8 MB user memory and 478 KB I/O memory for large applications.
  • Extensive I/O Capacity: Supports up to 128,000 discrete and 4,000 analog I/O points.
  • Advanced Task Handling: Executes up to 32 tasks with 100 programs per task for efficient processing.
  • Flexible Communication Options: Expandable with EtherNet/IP, ControlNet, DeviceNet, DH+, RIO, and more.
  • Built-In RS-232 Port: Provides serial communication for DF1, ASCII, and third-party protocol interfacing.
  • Redundancy Ready: Fully compatible with ControlLogix redundancy systems for high-availability designs.
  • Motion Integration: Supports SERCOS, analog encoder, SSI, and Ethernet/IP motion control solutions.
  • Robust Industrial Design: Wide temperature tolerance with strong shock and vibration resistance.

The 1756-L63 delivers the reliability and precision required for large, networked, and high-performance industrial automation systems.

Frequently Asked Questions about 1756-L63
Question: What is the 1756-L63?
Date Update:06/06/2025
Answer:

The 1756-L63 is a ControlLogix processor module (part of the Allen-Bradley ControlLogix family) used in large and complex automation systems.

Key specs include:

  • Memory: 8 MB
  • Communication: Multiple backplane communication channels
  • Redundancy capable for high-availability applications
  • Battery-backed RAM for data retention
Question: How do I wire the 1756-L63 processor?
Date Update:06/06/2025
Answer:
  • The processor itself plugs into a ControlLogix chassis (1756-A4, A7, A10, A13) and does not have field wiring directly.
  • Communication wiring (Ethernet, ControlNet, DeviceNet, etc.) is handled via communication modules (like 1756-ENBT for Ethernet).
  • The battery module (1756-BA2) and energy storage module (1756-ESMCAP) are connected directly to the 1756-L63.
Question: How do I program the 1756-L63?
Date Update:06/06/2025
Answer:
  • Use RSLogix 5000 or Studio 5000 Logix Designer software for programming.
  • Develop your ladder logic, function block, structured text, or SFC applications.
  • Download the program via:
    Ethernet (using 1756-ENBT or EN2T modules)
    Serial (RS-232) via the mini-DIN connector on the processor (requires the 1756-CP3 cable)
Question: How do I set up communication?
Date Update:06/06/2025
Answer:
  • Add communication modules (like 1756-ENBT for Ethernet) to the chassis.
  • In Studio 5000, configure the modules (IP address, drivers).
  • Create controller tags for I/O and communication with other devices.
Question: Can I use the 1756-L63 in a redundant system?
Date Update:06/06/2025
Answer:

Yes. The 1756-L63 supports redundancy for critical applications. Use Rockwell Automation’s redundancy configuration tools and guidelines in the redundancy user manual.
