1757-SRM 是 Allen-Bradley ProcessLogix 和 ControlLogix 系统的一个重要模块,它用于实现控制器的冗余配置,从而提高整个工业控制系统的可用性和可靠性。这种模块通过在两个不同的 ControlLogix 机箱上安装主控制器和辅助控制器来同步操作,确保在主控制器发生故障时,辅助控制器能够无缝接管控制任务,保证生产过程的连续性。
1757-SRM 模块具有以下特点:
两插槽模块,设计用于安装在 ControlLogix 机箱中。
带有集成的光纤端口,使用 62.5/125 微米多模光纤电缆与另一个机箱中的 1757-SRM 模块连接,形成同步链路。
模块状态显示功能,通过不同的 LED 指示灯提供关于模块运行状态的实时信息,包括主机箱指示(PRI LED)、通信和同步状态(COM LED)以及健康状态(健康状态 LED)。
该模块与多种 ControlLogix 机箱和系统电源兼容,包括但不限于 1756-A4、1756-A7、1756-A10、1756-A13 和 1756-A17 机箱,以及 1756-PA72、1756-PA75、1756-PB72 和 1756-PB75 系统电源。安装时,需要确保两个机箱的尺寸、模块安装和定位、系统电源和模块版本相匹配。
1757-SRM 模块的设计是为了满足关键工业应用的需求,这些应用需要在任何情况下都保持运行,通过冗余系统确保生产的连续性和安全性。
The 1757-SRM is an important module of the Allen-Bradley ProcessLogix and ControlLogix systems, which are used for redundant configuration of controllers to improve the availability and reliability of the entire industrial control system. This module operates synchronously by installing the primary and secondary controllers in two different ControlLogix cases, ensuring that the secondary controller can seamlessly take over control tasks in the event of a primary controller failure, ensuring continuity in the production process.
The 1757-SRM module has the following features:
Two-slot module designed for installation in the ControlLogix chassis.
With an integrated fiber port, the 62.5/125 micron multimode fiber cable is connected to the 1757-SRM module in another chassis to form a synchronous link.
The module status display function provides real-time information about the operating status of the module through different LED indicators, including the main box indicator (PRI LED), communication and synchronization status (COM LED), and health status (health LED).
The module is compatible with a variety of ControlLogix chassis and system power supplies, including but not limited to the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17 chassis. And 1756-PA72, 1756-PA75, 1756-PB72, and 1756-PB75 system power supplies. During installation, ensure that the dimensions, module installation and location, and system power supply and module version of the two chassis are consistent.
The 1757-SRM module is designed to meet the needs of critical industrial applications that need to remain operational in all circumstances, ensuring continuity and safety of production through redundant systems.
