Schneider 140CPU67160 Unity Hot Standby Processor

Redundancy Architecture in the Modicon Quantum Platform

The Schneider Electric 140CPU67160 is a Unity Hot Standby processor engineered for the Modicon Quantum automation platform. It operates at a clock frequency of 266 MHz and carries 1024 kB of internal RAM, with 512 kB allocated for data. This architecture supports process control and hot standby checks, enabling primary and secondary PLC synchronization over an optic fibre Hot Standby link rated for up to 4 km.

For engineers specifying redundant control, the 140CPU67160 delivers deterministic execution through a 1 ms master task and a 0.2 ms fast task. Instruction throughput reaches 10.28 Kinst/ms at 100% Boolean and 10.07 Kinst/ms at 65% Boolean with 35% numerical. These verified figures allow precise cycle-time budgeting before commissioning.

Electrical and Communication Specifications

The processor requires 2500 mA of bus current and provides integrated connections including one Modbus Plus port, one Modbus port, one USB port, and one MT-RJ multimode fiber optic connector for PLC interconnection. A female SUB-D 9 connector serves the Modbus Plus network, while an RJ45 connector handles the Modbus bus.

Local signaling includes a green LED for Ethernet activity and a red LED for Ethernet collision. The key switch controls memory port on/off functionality. For distributed I/O, the 140CPU67160 supports up to 63 stations on Modbus Plus and 31 stations via S908 remote I/O, with additional Ethernet Quantum and X80 remote I/O capacity.

I/O Capacity and Application Structure

Discrete I/O capacity reaches 31,744 inputs and 31,744 outputs for remote configurations, plus 8,000 inputs and 8,000 outputs per Modbus Plus distributed network. Analogue capacity includes 500 inputs and 500 outputs per Modbus Plus network, with 1,984 inputs and 1,984 outputs for remote arrangements. Local I/O remains forbidden in Hot Standby applications.

The application structure supports one cyclic or periodic master task, with fast, interrupt, and auxiliary tasks restricted in Hot Standby mode. Memory expands to 7,168 kB for program storage and 8 MB for file storage using PCMCIA cards. Six optional modules accommodate Ethernet, Modbus, Modbus Plus, Profibus DP, and Sy/Max protocols.
