In a redundant function implementation

In NA400 series PLC products, CPU401-0501 product is its representative products, which in addition to all NA400 series PLC as providing safe and reliable operation of  china programmable logic controller the system to all intelligent I / O design and a range of security, reliability, designed for protection, plc analog input modules but also with hardware redundancy. In a redundant function implementation, analog io module to achieve a complete scan of all data exchange, redundant communication rates up to 100 Mbps, users do not need any programming work and hot standby module, you can achieve redundancy, while hot-swappable replacement module can be flexibly applied to a single chassis and dual redundant system chassis redundant systems.
