Supports symbolic variable programming and flexible partitioning of program and data memory.

Performance Comparison of IC695CPE305 with Peer RX3i CPU Modules
The IC695CPE305 features a 1.1 GHz processor, 5 MB user memory and 5 MB flash memory. It integrates one built-in 10/100 Mbps Ethernet port and one RS232 serial port, and is engineered for mid-range basic process control applications.
Versus IC695CPE302: The CPE302 is limited to 2 MB user memory, restricting its use for large program deployment and extensive data logging. The CPE305 provides expanded memory to accommodate more control logic and historical data, while both models share the same processor framework and I/O reference table capacity.
Versus IC695CPE310: The CPE310 is fitted with 10 MB user memory to handle bigger control programs and high-volume data acquisition. The CPE305 has a smaller memory footprint and delivers better cost efficiency for medium-sized projects that do not demand intensive data recording.
Versus IC695CPE330: The CPE330 uses a 1.6 GHz dual-core processor and 64 MB user memory, equipped with two separate Gigabit Ethernet ports. It supports more concurrent network connections, redundant IP setup and greater communication throughput. Without gigabit networking and dual-Ethernet design, the CPE305 is not suited for high network traffic or redundant network topologies.
These mainstream RX3i CPUs maintain identical I/O reference table specifications. All support 32 Kbits of discrete I/O and 32 Kwords of analog I/O, and work with most RX3i and legacy Series 90-30 I/O modules.
The CPE305 keeps an onboard RS232 serial interface for direct connection with serial devices. In contrast, premium models such as the CPE330 omit the native serial port and require external communication cards for serial connectivity.
Scan performance: The CPE305 achieves stable execution of Boolean logic for standard control tasks. It underperforms the CPE330 when running complex algorithms, high-speed motion control and communication-heavy workloads.
Redundancy function: The CPE305 has no native CPU hot-standby redundancy. Premium variants including the IC695CRU320 support hot standby redundancy, which targets high-availability SIS and critical power control systems where the CPE305 cannot satisfy reliability demands.
Protocol support: All these CPUs are compatible with SRTP, Modbus TCP, EGD and OPC UA. The main distinction is the number of allowable concurrent connections; the CPE305 supports fewer simultaneous network sessions compared with the CPE330.
Cost profile: The IC695CPE305 occupies the mid-entry segment within the RX3i CPU family. It balances performance and budget for standard process control, water treatment and general machinery automation. The CPE330 and CRU320 are designated for large-scale, high-speed and high-availability systems.
