2015-06-26 11:44:37


ControlLogix® systems 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. Leverage the high-availability and extreme environment capabilities to meet your application needs.……

1756 ControlLogix Extreme Environment Controllers

Bulletin 1756 ControlLogix-XT™ Extreme Environment Controllers function in the same way and offer the same features as the ControlLogix Standard Controllers. The XT controllers leverage the Rockwell Automation® Integrated Archi­tecture™ control engine with enhancements to meet the needs of extreme environment applications, including conformal coating that extends product life in harsh, corrosive environments. In addition, an XT control system spaces modules in every other slot for thermal cushion and offers redesigned ventilation for increased air flow.

1756 ControlLogix Standard Controllers

Bulletin 1756 ControlLogix® Standard Controllers are suitable for process, motion, discrete, and high-availability applications. As part of the Rockwell Automation® Integrated Architecture™ system, these controllers use RSLogix™ 5000 programming software (L6 models), the Studio 5000™ environment (L7 models), and common network protocols. They offer common information capabilities. These high-performance controllers provide a common control engine with a common development environment for all control disciplines. Consider these controllers for more sophisticated machines and for connectivity to business systems.

1756 GuardLogix Safety Controllers

Bulletin 1756 GuardLogix® Safety Controllers have a two-processor architecture (1oo2) and are suitable for SIL 3 PLe applications. As part of the Rockwell Automation® Integrated Architecture™ system, these controllers use RSLogix™ 5000 programming software (L6 models) and the Studio 5000™ environment (L7 models). They offer common information capabilities and support CIP Safety over EtherNet/IP™ and ControlNet™ networks. These high-performance controllers provide a common control engine with a common development environment for all control disciplines. Consider these controllers for more sophisticated machines and for connectivity to business systems.

1756 GuardLogix Safety Controllers


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. Available in standard and extreme environment models.



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.



ControlLogix® systems offer Integrated Motion with support for Kinetix® and PowerFlex® drives on EtherNet/IP™ networks, and for Kinetix drives on Sercos™ interface. Select from a range of EtherNet/IP and Sercos interface module options with support for as many as 128 drives per EtherNet/IP module and as many as 16 drives per Sercos module. Analog interface modules are available for drives and actuators with analog interfaces.


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.

Redundancy Modules

Bulletin 1756 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. 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
