Schneider Electric 140CPU67060 Modicon Quantum Unity Hot Standby Processor

Description

This Unity processor is designed for the Modicon Quantum automation platform to provide high-availability control through Hot Standby functionality. Operating at a clock frequency of 266 MHz, the module features an onboard memory of 512 KB dedicated for data RAM, with support for expandable program and file storage via PCMCIA cards.

The processor facilitates robust system distribution, managing up to 63 distributed I/O stations and up to 6 Ethernet X80 remote I/O racks (racks supporting up to 6 drops). Local discrete and analogue I/O configurations are explicitly restricted in Hot Standby setups to preserve system architecture integrity. Integrated communication capabilities feature multiple connection types including a dedicated multimode fiber optic port utilizing the Hot Standby protocol, along with dedicated ports for Modbus, Modbus Plus, and USB connections. It is optimized for high-reliability process control and automated verification checks.

Features

• High-Availability Hot Standby: Features an integrated MT-RJ multimode fiber optic interface running a dedicated Hot Standby protocol to synchronize primary and secondary controllers.
• Scalable Memory Architecture: Provides 512 KB of internal data RAM, with expansion capabilities up to 8 MB for file storage and 7168 kB for application programs using PCMCIA cards.
• High-Speed Execution: Performs operations with an execution time of 0.0525...0.075 µs for Boolean instructions and 0.4...0.5 µs for floating-point calculations.
• Extensive Networking Range: Supports up to 3 local networks each for Modbus Plus, Ethernet TCP/IP, and Profibus DP, alongside remote and distributed AS-Interface mapping.
• Flexible Rack Compatibility: Designed to operate within standard Modicon Quantum mounting structures, aligning with system setups from 2 to 16 slots.
• Dedicated Task Management: Formatted to execute 1 cyclic/periodic master task, optimized specifically for deterministic process environment requirements.

Connections/Interfaces

Installation Guidelines

• System Redundancy Interconnection: Connect the primary and secondary processors using standard MT-RJ multimode fiber optic cabling. The architecture supports a maximum physical length of up to 4 km between the paired controllers.
• Rack Restrictions: Mount the processor securely into a compatible Modicon Quantum automation platform slot. Note that auxiliary tasks, timer interrupt tasks, standard interrupt tasks, I/O interrupt tasks, and periodic fast tasks are explicitly forbidden when running a Hot Standby application configuration.
• Memory Protection: Utilize the onboard functional hardware key switch to toggle the memory port on or off, protecting the configured data and program blocks from unauthorized local modifications.
• Network Segregation: Ensure proper termination on the Modbus Plus SUB-D 9 network line and monitor diagnostic LEDs to avoid communication collisions or packet losses across local paths.

FAQ

• What is the purpose of the fiber optic port located on this module?

  The MT-RJ multimode fiber optic interface is dedicated to running the integrated Hot Standby protocol, synchronizing primary and secondary processors over distances up to 4 km for seamless process control backup.

• Are local I/O cards permitted in the same rack as the processor during redundant operation?

  No. Local discrete and analogue I/O configurations are forbidden when the processor is implemented within a Hot Standby system topology. All I/O must be routed through distributed networks or Ethernet remote drops.

• How is program memory expanded if the 512 KB data RAM is insufficient for full applications?

  The module accommodates hardware memory expansion via PCMCIA cards, supporting up to 7168 kB for program storage and up to 8 MB for general file storage.

• What do the integrated diagnostic LEDs on the faceplate indicate?

  The faceplate includes two distinct LED status indicators: a red LED that alerts the operator to an active Ethernet collision and a green LED that indicates ongoing Ethernet communication activity.
