Schneider 140CHS11000 Hot Standby Module ‎

Product Overview

Schneider Electric 140CHS11000 is a standard module specifically designed for Modicon Quantum PLC systems. It supports hot standby redundancy, meaning that while the main controller module is operational, the standby module remains powered and in standby mode. In the event of a failure in the main module, the hot standby module can seamlessly take over control within an extremely short timeframe (typically within milliseconds), ensuring continuous system operation and data integrity.

The module uses fiber optic cables as the transmission medium, enhancing communication reliability and resistance to electromagnetic interference, making it particularly suitable for industrial environments with complex electromagnetic conditions.

Key Features

Hot Standby Redundancy: This is its primary function. The module provides redundancy and fault-tolerant switching capabilities, ensuring that the standby module can quickly take over in the event of a failure in the main controller or I/O module, preventing production interruptions.

High-Speed Communication: Supports a transmission rate of 10 Mbit/s, ensuring fast data exchange and minimal latency to meet the requirements of real-time control applications.

Fiber-Optic Connection: Uses fiber-optic cables as the communication medium, enhancing signal transmission stability and electromagnetic interference (EMI) resistance, suitable for long-distance or noisy environments.

Fast Switching: Fault switching time ranges from 13 to 48 milliseconds, ensuring a smooth transition between primary and backup modules without significantly impacting ongoing control logic.

Diagnostic Features: The module is equipped with multiple LED indicators to display module operational status, backup status, communication status, and fault information, facilitating rapid issue diagnosis by maintenance personnel.

Software Compatibility: Compatible with ProWORX 32 NxT V2.0 and Concept V2.0 or higher software versions, facilitating integration into existing automation platforms.

Usage

The 140CHS11000 module is used as follows:

Hardware Installation: Insert the module into the designated slot of the Modicon Quantum PLC rack, typically used in conjunction with the main CPU module.

Redundancy Setup: In a hot standby redundant system, two controllers (primary and standby) and two hot standby modules are typically required. Pair one 140CHS11000 module with the primary controller and the other with the standby controller.

Fiber Optic Connection: Connect the primary and standby modules using fiber optic cables via the RJ45 connectors on the modules to form a redundant communication link.

Software Configuration: In compatible programming software (such as Concept or ProWORX), configure the hot standby system parameters, including defining the roles of the primary and standby modules, switch logic, and communication settings.

System Commissioning: After configuration, perform comprehensive functional testing, simulate fault scenarios, and verify that the system can correctly and quickly complete the primary-standby switchover.
