• System Platform: Modicon Quantum High Availability Platform
• Purpose: Provides complete hardware for a redundant (1:1) Quantum PLC system
• Key Feature: Enables seamless switchover to a backup controller in case of primary failure

Complete Kit Contents

• Controller Units: 2 x 140CPU11302 Quantum CPUs (Main & Standby)
• Hot Standby Processors: 2 x 140CHS11000 (Manages synchronization and failover)
• Power Supplies: 2 x 140CPS11100 (Redundant power for each rack)
• Backplanes: 2 x 140XBP00600 (6-slot racks to hold components)
• Communication Processors: 2 x 140CRP93101 Remote I/O Processors (for network I/O)
• Synchronization Cable: 1 x Fiber Optic Cable (3m) for high-speed hot standby link
• Termination Kit: 1 x S908 Terminator Kit for network setup
• Documentation: 1 x Installation Manual

System Architecture & Function

• Creates two identical Quantum racks: one Primary and one Standby (Hot)
• The 140CHS11000 modules continuously synchronize memory and I/O data between the two CPUs via the fiber optic link
• In the event of a fault in the primary CPU, rack, or power supply, the standby system takes control within milliseconds with no program loss
• Maintains continuous operation for processes where unscheduled downtime is unacceptable

Environmental Specifications

• Operating Temperature: 0 to 40 °C (32 to 104 °F)
• Storage Temperature: 0 to 50 °C (32 to 122 °F)
• Operating/Storage Humidity: Up to 80% RH, non-condensing
• Designed for controlled industrial environments such as control rooms

Typical Applications

• Critical process control in chemical, oil & gas, and pharmaceutical industries
• Power generation and distribution control systems
• Water and wastewater treatment facilities
• Any application requiring maximum system uptime and fault tolerance

Packaging & Shipping

• The 140CHS41010 is shipped as one complete system kit.
• All components are packed together in secure, industrial packaging.
• Due to the value and quantity of items, shipping is carefully handled.
• Worldwide express shipping via FedEx, UPS, and DHL available with appropriate insurance.

Frequently Asked Questions (FAQ)

• What is a Hot Standby system? It is a redundant architecture where a secondary, identical controller runs in parallel with the primary, ready to take over instantly if the primary fails, ensuring continuous operation.
• What is the fiber optic cable for? It is the dedicated, high-speed link for synchronizing data between the primary and standby 140CHS11000 processors. Fiber optics provide noise immunity and fast data transfer.
• Does this kit include I/O modules? No, this kit provides the redundant controller infrastructure (CPUs, racks, power, comms). Analog and digital I/O modules must be purchased separately and installed into the provided backplanes.
• How is it programmed? You program the system as a single entity using Unity Pro software. The hot standby processors handle the replication of the program and data to the standby CPU automatically.
• What is the role of the 140CRP93101 modules? They are remote I/O scanners, allowing the redundant controllers to communicate with distributed I/O drops over a Modbus Plus or Ethernet network.
• Is this for a new system or can it upgrade an existing one? It is typically used to build a new redundant system. Upgrading an existing simplex system to hot standby is a major retrofit and may require different components.
• Where should it be installed? For best reliability, the two racks should be installed in separate locations or enclosures to protect against localized physical damage or environmental events.
