Centered around a 1 GHz processor, this module integrates advanced features including dual-CPU hot standby redundancy, dual serial port communication, and Error Checking and Correction (ECC). Through the synergistic optimization of hardware and software, it provides a stable and reliable control hub for industrial automation systems, helping enterprises achieve efficient and safe production objectives under complex operating conditions.
Data Sheet:
Basic Module Information and Core Functions
Model: IC695CRU320
Series: RX3i PacSystem
Positioning: A dual-CPU hot standby redundancy module designed for high-reliability industrial automation scenarios.
Core Functions:
Equipped with a 1 GHz processor, supporting redundancy switchover and data synchronization. The switchover time ranges from a minimum of 3.133 ms to a maximum of 1 logic scan cycle. It enables data synchronization of up to 2 MB via redundancy links (such as IC695RMX128) and supports up to 2 redundancy links.
Features two built-in serial ports (COM1/COM2, compatible with RS-232/RS-485), supporting protocols such as Modbus RTU Slave, SNP Slave, and Serial I/O. These ports can be used for firmware upgrades and communication with external devices (e.g., HMIs, sensors), with port activity indicated by LEDs.
Incorporates Error Checking and Correction (ECC) functionality, supporting single-bit error correction and multi-bit error detection to enhance memory data reliability.
