Allen Bradley 1756 ControlLogix FAQ

Whether you’re maintaining an existing system or planning a new installation, it’s important to understand the capabilities and options available in the 1756 ControlLogix Series. Below you’ll find answers to frequently asked questions to help guide your decision-making process, reduce downtime, and ensure compatibility with your industrial automation setup.

What is the Allen Bradley 1756 ControlLogix Series?

The 1756 ControlLogix Series is a modular programmable automation controller (PAC) platform developed by Rockwell Automation. It allows users to build customized control systems by combining chassis, power supplies, I/O modules, and communication adapters.

What types of modules are available in the 1756 ControlLogix lineup?

The 1756 ControlLogix Series includes a broad range of modules such as:

  • Processor modules (e.g., 1756-L8x, 1756-L7x)
  • Input/output (I/O) modules (analog, digital, specialty)
  • Communication modules (EtherNet/IP, ControlNet, DeviceNet, Profibus)
  • Redundancy and safety modules
  • Power supply modules and chassis

Each module is hot-swappable and designed to integrate seamlessly into the ControlLogix platform.

What communication options are supported by 1756 ControlLogix controllers?

ControlLogix controllers support multiple industrial protocols via plug-in communication modules, including:

  • EtherNet/IP
  • ControlNet
  • DeviceNet
  • Profibus (via third-party interface)
  • Modbus TCP/RTU (via bridging modules or configuration)

Many applications utilize multiple protocols to connect with drives, HMIs, safety systems, and remote I/O devices.

Can I use 1756 ControlLogix components with other Rockwell systems?

Yes. ControlLogix modules can often communicate or integrate with other Rockwell platforms like CompactLogix or Flex I/O through compatible communication interfaces and Studio 5000 software. However, always check system compatibility and firmware levels before deployment.

Are 1756 ControlLogix components backwards compatible with older chassis or firmware?

Many 1756 ControlLogix modules are designed with backward compatibility in mind, but compatibility depends on the specific controller, module, chassis revision, and firmware version. For example, newer 1756-L8x controllers may require specific chassis revisions and support only certain firmware ranges.

What should I consider when upgrading a legacy ControlLogix system?

When upgrading from older ControlLogix hardware (such as L6x or early L7x controllers), consider your current firmware version, I/O module compatibility, communication infrastructure, and software licenses. Modern L8x controllers offer significant performance gains but may require firmware updates and chassis replacements.
