Occupied slots: Dual slot width (occupying 2 rack slots), which needs to be installed in the slot next to the main controller

Display screen: 4-character alphanumeric display screen, used for runtime information and controller diagnosis

Certification:

Compliance standards: CCC, CE, CSA, C-Tick, KC, MARINE, RCM, UL (Specific certifications need to be checked on the product label as the date of manufacture may vary)

Safety certification: Supports up to SIL 3 and PL e safety levels.

Programming and Configuration

Compatible software: Studio 5000 Logix Designer (formerly RSLogix 5000), used for programming, configuration and diagnosis.

Supported programming languages: Relay Ladder, Function Block Diagram, Sequential Function Chart, Structured Text.

Function

Security Partner Controller

1756-L7SP, as the safety partner controller in the GuardLogix system, pairs with the main safety controller to form a 100.2 safety architecture, providing safety functions up to SIL 3 and PL e.

Ensure that the system can still maintain safety functions when the main controller fails and enhance the reliability of the system.

High-reliability design

The integrity of data and programs is ensured in the event of power failure or malfunction through independent isolation and capacitive energy storage modules (without the need for batteries).

Supports live plug and unplug (RIUP), which is convenient for maintenance and replacement.

Communication flexibility

Programming and configuration can be carried out through the USB port, supporting multiple industrial communication protocols and adapting to different network environments.

Data can be shared with the main controller and other devices via EtherNet/IP or ControlNet network, and it supports Producer/Consumer technology.

Status monitoring and diagnosis

It is equipped with a built-in 4-character alphanumeric display screen, showing the operating status, fault codes and diagnostic information, which is convenient for on-site monitoring and troubleshooting.

The SD card stores diagnostic data for Rockwell Automation to analyze the causes of faults (it is recommended to use the official SD card, such as 1784-SD1 or 1784-SD2).

Modularization and scalability

Installed in the ControlLogix rack, it can be seamlessly integrated with other modules such as I/O modules and communication modules.

Support multi-controller configuration and adapt to distributed control systems (DCS) or high-availability systems.

Programming support:

Programming is carried out using Studio 5000 Logix Designer, which supports multiple programming languages and simplifies the development of security logic and standard logic.

Support event-triggered tasks and state change (COS) functions to optimize response speed.

Application scenarios

Safety-critical applications: Widely used in scenarios requiring high safety levels (SIL 3, PL e), such as safety interlock systems in the chemical, oil and gas, pharmaceutical, and food and beverage industries.

Manufacturing industry: It is used for safety control on production lines, such as robot systems, conveyor belts or automated assembly lines, to ensure the safety of personnel and equipment.

Process control: Applied to complex processes that require redundant control, such as oil refineries, power plants or water treatment facilities, to ensure that the system can still maintain safe operation when the main controller fails.

Distributed control system: Integrated into the distributed I/O system via EtherNet/IP or ControlNet network, it is suitable for large factories or remote monitoring applications, such as the PlantPAx DCS platform.

Traditional system maintenance: 1756-L7SP is used for the maintenance or upgrade of existing GuardLogix systems, and is particularly suitable for scenarios that require high security and redundancy.
