The Schneider Electric 140CPU67060 is a specialized Unity Hot Standby processor for the Modicon Quantum automation platform. It provides high-speed execution and redundant processing for mission-critical industrial systems. The unit features a 266 MHz clock speed and a 1024 kB internal RAM capacity. This hardware ensures consistent uptime by allowing a secondary backup unit to take control instantly if the primary module fails.
System Configuration and Constraints
The 140CPU67060 follows a specific application structure to maintain Hot Standby integrity. Certain standard PLC tasks are restricted in redundancy mode to prevent synchronization errors between the primary and standby units.
- Supports one cyclic or periodic master task for main logic.
- Periodic fast tasks are restricted in Hot Standby configurations.
- I/O interrupt and timer interrupt tasks are disabled to ensure data consistency.
- Auxiliary tasks are prohibited during redundant operation.
- Integrated key switch for mode selection and security.
