Key Features

1. Hot Standby Redundancy
    
   Real-time data mirroring between master & standby CPU; seamless automatic switchover on main CPU fault, no process interruption.
2. Safety Logic Execution
    
   Certified safety processor, independently runs safety interlock, emergency stop, over-limit protection logic for critical equipment.
3. Multi-network Integration
    
   Dual Ethernet isolates control network & management network, connect HMI, SCADA, remote I/O and upper factory MES system simultaneously.
4. On-site Diagnostics
    
   Front LCD directly shows rack fault, I/O error, communication alarm, CPU status without extra software.
5. Expandable Storage
    
   PCMCIA card supports data logging, recipe storage, program backup for long-term process record.
