Technical Specifications Redundancy synchronization interface; High-speed data mirroring; Series 90-70 rack mount.
Functional Features Real-time data synchronization between redundant CPUs; Redundancy state monitoring; Fault switchover control.
Application Scenarios Critical redundant control systems in power generation, petrochemical and continuous production lines requiring no interruption.
Performance Parameters Fast data mirroring; Seamless master/standby switch without system interruption.
Structural Characteristics Series 90-70 rack pluggable module, dedicated redundancy communication port, status LEDs.
Working Principle Keep real-time synchronization of program and I/O data between primary CPU and standby CPU. When main CPU fails, assist system to switch to standby CPU automatically.
Installation Requirements Install in redundant Series 90-70 rack; Use dedicated redundancy cable; Ensure good cabinet grounding.
Usage Notes Verify redundancy switchover function after installation. Backup CPU configuration before maintenance.
