ControlLogix Control System

Bulletin 1756 ControlLogix Programmable Automation Control System

Our ControlLogix® controllers use a common control engine with a common development environment to provide high performance in an easy-to-use environment. Tight integration between the programming software, controller and I/O modules reduces development time and cost at commissioning and during normal operation. You can perform standard and safety control in the same chassis for a truly integrated system.

Features

  • Provides premier high-speed, high-performance, multi-disciplined application control
  • Provides fully redundant controller architecture with bumpless switchover and high availability
  • Provides modular network communications
  • Offers broadcast range of communication and I/O options
  • Provides time-synchronization capabilities for first fault, process sequencing and other applications
  • Offers select products that are TÜV-certified for use in SIL 2 applications

Rockwell Automation Integrated Architecture Solutions provide the foundation to drive plantwide optimization efficiently and effectively, enabling you to respond competitively to the economy and changes in consumer demand.

Our Extreme Environment (XT) [PDF] system includes control, communication, and distributed I/O products that extend the benefits of the Rockwell Automation Integrated Architecture™ to applications with more demanding environmental conditions.

Controllers

Bulletin 1756 ControlLogix® and GuardLogix® Controllers include a range of controllers to suit standard, safety, redundant and extreme environment applications. With memory options ranging 2...32 MB, these controllers provide fast processing in a single integrated solution for all types of applications. Network options include EtherNet/IP™,ControlNet™, DeviceNet™, DH+™, Remote I/O, RS-232, and many third-party process and device networks.

Redundancy Modules

Bulletin 1756 and 1757 ControlLogix® Redundancy Modules support fully redundant controller architectures with no additional programming required. Programs are cross-loaded automatically from the primary to the secondary controller, and the primary automatically updates the secondary with data changes to maintain controller synchronization. If the primary fails, control switches to the secondary automatically, and highest priority functions are guaranteed a ‘bumpless transfer.' Controller redundancy is transparent to any devices connected over an EtherNet/IP™ or ControlNet™ network. Select the ControlLogix extreme environment redundancy module for applications that must run in extreme environments.

Communication Modules

The ControlLogix® Communication Modules support EtherNet/IP™, ControlNet™, DeviceNet™, Data Highway Plus™, Remote I/O, Foundation Fieldbus, serial, DH-485 and SynchLink™ networks. Interface using ControlLogix communication modules via a ControlLogix gateway (without a controller in the gateway chassis), or interface directly to a ControlLogix controller. ControlLogix extreme environment communication modules are available for EtherNet/IP, ControlNet, Data Highway Plus and Remote I/O networks.

I/O Modules

Bulletin 1756 ControlLogix® I/O modules provide a full range of digital, diagnostic digital, analog, and motion control I/O to meet your application needs. Any of the I/O modules can be used in the local chassis of a ControlLogix controller. With the exception of the motion control modules, these modules can be used in a chassis linked to a ControlLogix controller across ControlNet™ or EtherNet/IP™ networks in a ControlLogix system.

Motion Modules

Add the Bulletin 1756 SERCOS Interface Motion Modules or Analog Interface Motion Modules to your ControlLogix® system to leverage the power of the Kinetix® Integrated Motion solution. The Logix platform supports motion control components that work in a wide variety of machine architectures.

Power Supplies

Use the Bulletin 1756 ControlLogix® Power Supplies with the 1756 ControlLogix chassis to provide 1.2V, 3.3V, 5V and 24V DC power directly to the chassis backplane. These power supplies are available in standard, redundant and extreme environment models.

Chassis

Modular ControlLogix® and GuardLogix® systems require Bulletin 1756 I/O Chassis. These chassis are designed for horizontal-only, back-panel mounting. You can place any module into any slot. The backplane provides a high-speed communication path between modules. Chassis are available in standard and extreme environment models.

Software

Use RSLogix 5000 programming software from Rockwell Software® to design and configure your ControlLogix® or GuardLogix® system.

The controllers and modules you select, along with your network configuration, determine what additional software packages you need to configure and program your system. Additional required software may include RSNetWorx configuration software and RSLinx communication software.
