6ES7960-1AA06-0XA0 Siemens SIMATIC S7-400H Synchronization Module

Product parameters

Basic attributes: Specifically designed for the S7-400H redundant controller, it is a key component for achieving synchronous operation of dual cpus. It is only compatible with the S7-400H system and not applicable to other series of PLCS.

Performance parameters: Supports long-distance synchronization, with the maximum synchronization cable length reaching up to 10 kilometers, meeting the synchronization requirements of decentralized equipment layout in large industrial sites. It features high synchronization accuracy, ensuring that the operating status of the primary and backup cpus in the redundant system is consistent in real time, and the switching delay is extremely low.

Environmental parameters: Operating temperature range -25 ℃ to +60℃, suitable for complex temperature variation environments in industrial sites. The protection grade is IP20. It needs to be installed in a protective cabinet to resist the influence of dust and moisture.

Physical parameters: Compact structure, light weight (about 0.06kg), installed on standard rails, compatible with the installation frame of S7-400 series modules, facilitating system integration.

Function

Redundant synchronous control: The core function is to achieve real-time data synchronization between the main CPU and the standby CPU in the S7-400H system, including program execution status, process data, fault information, etc., ensuring that the system operates without disturbance during the primary and standby switching and guaranteeing production continuity.

Long-distance signal transmission: Through dedicated synchronous cables, synchronous signals can be stably transmitted within a range of 10 kilometers, making it suitable for redundant control of distributed equipment in large factory areas without the need for additional relay devices.

Anti-interference design: Built-in electromagnetic compatibility (EMC) protection circuit, capable of resisting electromagnetic interference in industrial sites (such as interference from motors, frequency converters and other equipment), ensuring stable and reliable synchronous signals.

Status monitoring and diagnosis: The diagnostic function of the S7-400H system can be used to monitor the operation status of the module in real time. When a fault occurs, alarm information can be promptly fed back, facilitating rapid location and maintenance.

Application scenarios

In large-scale process industries: In key control systems of continuous production industries such as petrochemicals, metallurgy, and power (such as large-scale reaction devices, steel rolling production lines, and generator set control), as a core component of redundant systems, it ensures the synchronization of primary and backup cpus to prevent production interruptions caused by single-point failures.

High-reliability production lines: For production lines in industries such as automotive manufacturing and semiconductors that have extremely high requirements for equipment availability, this module is used to achieve redundant control, ensuring the continuous operation of key equipment such as welding robots and precision processing equipment, and reducing downtime losses.

Infrastructure automation: In urban rail transit signal systems, large water treatment plants and other infrastructure, it is used for the synchronous control of equipment at decentralized stations to ensure the coordinated operation of each subsystem and enhance the stability and safety of the overall system.

Long-distance distributed system: It is suitable for distributed control systems in factories with large spans (such as large mines and ports), achieving synchronization of redundant equipment in different areas and ensuring unified scheduling and reliable operation of the entire system.
