Each rack supports 16 I/O modules, and the maximum number of local I/O points can reach 2048 (digital + analog). Support remote I/O expansion (connecting to distributed networks via communication modules such as PROFIBUS-DP, DeviceNet, EtherNet/IP, etc.)

Communication interface It is equipped with 1 RS-232C programming/communication interface (supporting Modbus RTU protocol for configuration download and HMI/SCADA communication), and 1 optional communication expansion slot is reserved (can install IC693CSE series communication modules to expand interfaces such as PROFIBUS-DP and Ethernet).

Power supply parameters: Powered by a Series 90-30 standard power module (such as IC693PWR321), operating voltage DC 5V, typical power consumption approximately 5W, peak power consumption 8W

Working environment: Working temperature 0℃ to 60℃, storage temperature -40 ℃ to 85℃. Relative humidity 5% - 95% (no condensation), anti-electromagnetic interference (EMC) complies with EN 55011/EN 55022 Class A and UL 1950 standards

Mechanical characteristics: Compatible with Series 90-30 standard 35mm DIN rail installation, module width approximately 64mm, wiring with front connectors (GE Fanuc IC693CBL300/301 series front connectors are recommended)

Programming and Configuration: Supports GE Fanuc VersaPro and Concept programming software, compatible with four programming methods: ladder diagram (LD), Function block diagram (FBD), structured text (ST), and sequential function diagram (SFC), and supports online monitoring, program modification and fault simulation

Diagnostic function: Integrated power supply (PWR), operation (RUN), fault (ERR), communication (COM) status indicator lights, supporting multi-level diagnosis such as I/O module offline, memory anomaly, communication fault, program error, etc. Detailed fault codes and real-time status data can be read through programming software

Function

Enhanced computing and control capabilities: High-speed execution efficiency of 0.08 μs/Boolean instructions, capable of handling more complex logical operations, timing control, and batch data processing. Supports up to 16 PID loops (double that of CMM301), suitable for complex scenarios where discrete control and continuous process control are mixed

Large-capacity memory and expansion flexibility: 256 KB default program memory + 128 KB data memory, meeting the storage requirements of large user programs and multi-variable data processing; Supports memory card expansion, capable of storing multiple versions of programs, fault logs and process parameter backups

Multi-dimensional I/O expansion: The local I/O expansion capability is doubled (up to 2048 points), allowing for the integration of more digital, analog, and special function modules (such as high-speed counting, pulse output, and temperature acquisition modules). Support remote distributed I/O networking, covering a wider range of control scenarios

Communication expansion and compatibility: The built-in Modbus RTU interface meets the basic communication requirements. The reserved communication expansion slots can flexibly add interfaces such as Ethernet and PROFIBUS-DP to achieve seamless communication with distributed devices, upper-level systems, and third-party PLCS

High-reliability data protection: The dual power-off retention design of supercapacitors and optional batteries ensures that critical data such as user programs, PID parameters, and counter values are not lost after power failure. Once power is restored, it automatically resumes operation without the need for manual intervention

Convenient diagnosis and maintenance: Multi-level fault diagnosis function, quickly locate the fault point (such as a certain I/O module failure, communication link interruption) through indicator lights and software; Supports online program download and real-time parameter modification, allowing system debugging and upgrading to be completed without shutting down the system

Strong compatibility: Fully compatible with all I/O modules, communication modules and programming software of the Series 90-30 series. It can directly replace the CMM301 CPU to achieve system performance upgrade without the need to replace other hardware or rewrite programs

Application scenarios

Medium and large-scale discrete manufacturing production lines: automotive parts assembly lines (multi-station collaboration, robot linkage), electronic equipment assembly lines (multi-process timing control, quality inspection linkage), large-scale packaging production lines (multi-machine synchronization, sorting and grading control), controlling a large number of solenoid valves, contactors, servo drivers and other equipment

Complex process control scenarios: medium-sized chemical reaction vessels (multi-parameter PID control: temperature, pressure, flow rate, liquid level), pharmaceutical liquid preparation and fermentation systems (multi-loop precise temperature control, flow rate regulation), small-scale water treatment plants (interlocking control of flocculation, sedimentation, and filtration processes). Process data is collected through analog modules and control signals are output to regulate the speed of valves and pump sets

High-end automation for general machinery: Large injection molding machines (full process timing of mold closing, injection molding, pressure holding, and ejection + pressure/flow control), printing machines (tension control, speed synchronization, registration control), CNC machine tools (multi-axis auxiliary action control, tool management, and processing technology linkage)

Medium and large-scale systems in warehousing and logistics: medium-sized stereoscopic warehouses (storage location management, stacker crane movement/lifting/storage and retrieval linkage, multi-conveyor line transfer control), logistics sorting centers (multi-channel sorting logic, barcode recognition linkage, sorting efficiency optimization control)

Energy and Infrastructure Control: Small substations (interlocking control of distribution switches, load monitoring), industrial boilers (combustion control, water level/pressure regulation), central air conditioning chiller units (interlocking control of compressors, pumps, and cooling towers, and communication with building automation systems (BMS))

System upgrade and capacity expansion: For performance upgrade or capacity expansion scenarios of the existing Series 90-30 system (CMM301 CPU) (such as adding new workstations on the production line or increasing process complexity), directly replacing the CPU can enhance the computing speed and I/O expansion capability, and be compatible with the original hardware and programs

Customized testing and industrial equipment: Core control for industrial inspection equipment (multi-parameter synchronous acquisition and control, complex test process execution), large-scale test benches in scientific research laboratories (multi-variable closed-loop control, data recording and analysis), and specialized equipment (such as lithium battery production equipment, photovoltaic module inspection equipment)
