Reset function: Equipped with a reset button, it is only effective when the device is turned on or restarted. Attempting to reset at other times will not damage the controller or cause data loss, but it is ineffective.

Function

Security Partner Controller

1756-L8SP, as the safety partner controller in the GuardLogix 5580 system, pairs with the main safety controller to form a 1002 safety architecture, providing safety functions up to SIL 3 and PL e, and meeting global safety standards (such as IEC 61508, EN ISO 13849-1).

Maintain safety functions when the main controller fails to ensure system reliability.

High-reliability design

Ensure the integrity of data and programs in case of power failure or malfunction through independent isolation and capacitive energy storage modules (without battery required).

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.

Supports integrated motion control on EtherNet/IP and CIP secure network connection, allowing security data to be shared among GuardLogix controllers.

Support Producer/Consumer technology to optimize data transmission efficiency.

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 fault investigation.

The SD card stores diagnostic data for analysis by Rockwell Automation.

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.

Integration of safety and standard control: Used in conjunction with the main controller, it provides a single software platform (Studio 5000) for safety and standard control, simplifying system design and maintenance.

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 safe operation when the main controller fails.

Integration of motion and safety: Integrated motion and safety control supporting Kinetix 5700 and PowerFlex 755 drivers, suitable for single-controller or multi-controller motion safety configurations.

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-L8SP is used for the maintenance or upgrade of the existing GuardLogix 5580 system, and is particularly suitable for scenarios that require high security and redundancy.
