III. Functional Features

(I) High Computing Efficiency to Support Complex Control Logic

With "32-bit RISC processor + optimized instruction set" as its core, GE Fanuc IC698CPE040-JP achieves efficient computing and complex control:

Microsecond-Level Instruction Execution: The execution speed of 0.1μs per basic instruction enables rapid processing of multi-equipment collaborative logic. For example, in an auto parts welding line, to control the collaborative work of 32 welding robots, 16 conveyor belts, and 8 detection sensors, the PLC needs to complete a logic scan (including equipment status reading, welding parameter calculation, and action command issuance) every 10ms. The computing speed of IC698CPE040-JP ensures that the scan cycle is stably within 8ms without logic delay.
Adaptation to Multiple Programming Methods: It supports four programming methods (LD/FBD/ST/SFC) to adapt to different control scenarios. For instance, simple equipment start-stop control uses Ladder Diagram (LD) programming, which is intuitive and easy to understand; complex PID temperature adjustment adopts Function Block Diagram (FBD) programming, with a modular design for easy modification; large-volume data processing (e.g., product counting and statistics) uses Structured Text (ST) programming, featuring concise and efficient code.
128-Channel Precise PID Adjustment: Built-in 128 PID loops support self-tuning and feedforward compensation, adapting to process control scenarios. For example, in a food filling production line, it is necessary to control the liquid level of 8 filling heads (target value: 500ml, error ≤±5ml). The PLC collects liquid level signals (4-20mA) in real time through the PID adjustment loop, calculates and outputs valve control signals. The self-tuning function can optimize PID parameters (proportional coefficient, integral time, derivative time) within 30 seconds to ensure that the liquid level control accuracy meets the standard.

(II) Flexible Expansion to Adapt to Diverse Needs

Through multi-rack expansion and compatibility with all types of modules, the module meets control needs of different scales and scenarios:

Large-Scale Expansion with 8 Racks: Supporting up to 8 expansion racks, it covers all needs of small and medium-sized systems. For example, in an electronic equipment assembly workshop, 1 CPU rack (IC698CPE040-JP) is matched with 3 expansion racks, which are installed with digital I/O modules (collecting 320 equipment statuses), analog I/O modules (controlling 48 channels of temperature/pressure), and motion control modules (driving 16 servo motors) respectively. This realizes the integration of "equipment control + process adjustment + motion drive" without the need for additional controllers.
Compatibility with All Types of Modules: It is compatible with all modules in the RX3i series, allowing flexible function combination. For example, in lithium battery testing equipment, the CPU rack is installed with analog input modules (collecting battery voltage/current) and digital output modules (controlling testing fixtures), while the expansion rack is installed with high-speed counting modules (collecting encoder signals to calculate battery transmission speed) and communication modules (connecting testing instruments). The modules support plug-and-play without complex adaptation.
SD Card Data Expansion: Supporting 32MB SD card expansion for program backup and historical data storage. For example, in the control of chemical reaction kettles, the PLC automatically backs up the control program through the SD card daily (to avoid program loss) and stores historical data of the reaction kettle's temperature and pressure (recorded once per second, storing data for up to 3 months), facilitating later process tracing and fault analysis.

(III) Industrial-Grade Protection to Adapt to Complex On-Site Conditions

In response to harsh conditions in industrial scenarios, the module enhances protection for hardware durability:

Wide Temperature and Environmental Adaptability: The operating temperature range of 0℃~+60℃ covers most industrial scenarios. For example, in an electronic workshop in southern China in summer (ambient temperature 55℃), the module operates for a long time without performance degradation, and the CPU computing speed fluctuation is ≤5%; in a food cold storage in northern China in winter (ambient temperature 5℃), the module can start without preheating, and the program loading time is ≤2 seconds.
Vibration and Shock Resistance: The 5g vibration resistance rating adapts to vibrations from workshop equipment. For example, in a machine tool processing workshop (vibration 3g, 10Hz~300Hz), the module is installed in a control cabinet, ensuring uninterrupted communication with expansion modules and no abnormal fluctuations in I/O data; when subjected to a 20g shock (e.g., tool collision) during installation and maintenance, the internal circuit remains undamaged, and programs and data are not lost.
Oil and Dust Proof: The shell is made of ABS flame-retardant material with an IP20 protection rating (when used with a control cabinet with IP54 rating) to resist workshop pollutants. For example, in a mechanical processing workshop (with much oil and metal dust), the module operates for a long time without terminal oxidation, and the communication interface contact resistance is ≤50mΩ, ensuring stable signal transmission; the cable connector adopts a waterproof design to prevent water ingress in humid environments during the rainy season.

(IV) Intelligent Diagnosis and Convenient Operation & Maintenance to Reduce Management Costs

Through fault diagnosis and remote monitoring, the module simplifies the operation and maintenance process and improves management efficiency:

Real-Time Fault Diagnosis: Built-in dual hardware and software diagnosis functions support error code output. For example, when an expansion module is offline, the PLC reports the error code "E012 = No response from Module in Expansion Rack 2" through the LED indicator (flashing fault light) and Ethernet interface. Maintenance personnel can check the fault location and cause on the HMI, reducing maintenance time by 60%.
Remote Programming and Monitoring: Remote programming and status monitoring are realized through the Ethernet interface. For example, maintenance personnel can remotely modify the PLC program (e.g., adjust PID parameters) and monitor equipment status (e.g., "Liquid Level of Filling Head 1 = 498ml", "Speed of Servo Motor 3 = 1500rpm") in the central control room using GE Fanuc Proficy Machine Edition software, without on-site operation, reducing downtime.
Data Interaction and Tracing: Supporting Modbus TCP and OPC UA protocols to realize data interaction with MES systems. For example, in an auto parts production line, the PLC uploads data such as "production quantity (1000 units)", "qualified rate (99.5%)", and "fault times (2 times)" to the MES system via the OPC UA protocol. The MES system generates production reports, facilitating managers to grasp production progress and quality and realize full-process data tracing.
