Quantum CPU Module
Description

Acerca de este producto

aquí está todo lo que necesitas saber

The Modicon 140 CPU 434 12A is a processor module for the Quantum range of programmable logic controllers (PLCs). This CPU is a Hot Standy option processor and provides automatic switchover in the event of a primary controller failure. 

Modicon 140CPU43412A at a glance:

  • Improves reliability by removing the intermediate supervisor controller
  • System control transfers occur in either direction increasing system uptime by eliminating the master-slave relationship
  • Integrity of the user programs are verified and compared in both controllers to ensure high security
  • High-speed fiber optic communication link between processors minimises scan impact and improves productivity
  • Primary I/O state table transfers to the standby controller every scan or in multiple scans by providing up-to-date system status and higher system integrity
  • Software control of Modbus and Modbus Plus ports enables host computer communications to either controller with no custom communication drivers
  • New configuration extension mode provides greater flexibility in state RAM transfer
  • An optional ladder logic function block delivers an easy migration path for 984/800 Series hot standby users
  • The hot standby system is compatible with Modicon TSX Quantum controllers and S908 remote I/O systems for cost-effective system design
