Functions Compatible With Redundant System

Redundant configuration of the entire system, including the CPU, the power supply, and the base unit. Hot standby system for the control and standby systems online module change both backup and separate mode available. Large-capacity data tracking: Large-capacity device data transfer (100 kwords) from the control system to the standby system. Network system compatible with redundant system: Switchover in case of MELSECNET/H or Ethernet module malfunction or network wire disconnection.
