Redundancy Control

Hot-standby redundancy

Hot-standby redundancy

  • Two master CPUs
  • Automatic matching of the master CPUs
  • Smooth switchover
  • Chronological synchronization of all stations
  • Configuration and monitoring in the SolutionCenter
  • Expanded diagnostic and programming interfaces for monitoring and analysis of redundancy status
  • Network redundancy included
  • Freely adjustable switching time, automatic switchover in case of error

Warm-standby redundancy

Warm-standby redundancy

  • Two master CPUs
  • Diagnostic interface for monitoring and analyzing the redundancy status
  • Slaves decide from which CPU the data packet is applied (voter)
  • Switching time configurable
  • Matching of the master CPUs not integrated

Network redundancy

Network redundancy

  • One master CPU
  • Redundant communication (cyclic and acyclic communication)
  • Easy configuration in development environment, integrated diagnostics (status, quality)
  • Programming interface, libraries and system variables for easy creation of applications
  • Slaves as smart substations
  • Network switchover in the same PLC cycle
