The module supports visual programming and parameter configuration through configuration software such as ABB Symphony Plus Engineering and Control Builder M. It has built-in rich industry application function blocks (such as turbine control function block and boiler regulation function block), without the need for additional driver development, greatly reducing the system integration cycle.

2.5 Comprehensive fault diagnosis and redundancy capability

The module has a built-in full link fault diagnosis mechanism, which can monitor the working status of core components, power stability, input and output signal integrity, and bus communication link quality in real time. When problems such as channel short circuit, signal disconnection, power supply abnormality, ADC/DAC conversion failure are detected, the fault status is immediately output through the module panel indicator light, and the fault information (including fault type, channel number, occurrence time) is uploaded to the controller and upper monitoring system through the communication bus, making it easy for operation and maintenance personnel to quickly locate the problem. At the same time, the module supports 1:1 hot redundancy configuration, and the main and backup modules achieve real-time data synchronization through dedicated redundant links, with a fault switching time of ≤ 10ms, ensuring uninterrupted control process and improving system reliability.

Typical application scenarios

4.1 Control of Steam Turbine Generator Sets in the Power Industry

In the digital electro-hydraulic control system (DEH) of steam turbine generator units in thermal power plants and nuclear power plants, the XVC722AE101 module serves as the core control unit, undertaking key tasks such as speed regulation, load control, and valve servo drive. The module collects parameters such as turbine speed (magnetic resistance sensor signal), shaft vibration, tile temperature, and main steam pressure/temperature through the AI channel. After internal PID calculation and logic judgment, it outputs control signals through the AO channel to drive the action of the electro-hydraulic servo valve, accurately adjusting the opening of high and medium pressure valves, and achieving stable control of turbine speed (control accuracy ± 1rpm) and power generation load. When faults such as excessive speed and vibration are detected, the module quickly executes interlocking logic and triggers emergency stop commands through the DO channel to ensure the safe operation of the unit.

4.2 Precise Control of Petrochemical Reactors

In the control system of large-scale chemical plants such as ethylene cracking furnaces and polyethylene reactors, modules can achieve collaborative control of multiple parameters in the reaction process. The temperature (thermocouple signal), pressure (pressure transmitter 4-20mA signal), liquid level (differential pressure transmitter signal), and feed flow signal inside the reaction kettle are collected through the AI channel. After being calculated by the internal cascade PID algorithm of the module, the opening of the feed valve, heating device power, and stirring motor speed are adjusted through the AO channel to ensure that the reaction parameters are stable within the process requirements. Its high-precision signal processing capability can maintain the temperature control accuracy of the reaction at ± 0.5 ℃, meeting the stringent requirements for parameter stability in chemical reactions; At the same time, the fault diagnosis function of the module can timely detect problems such as sensor disconnection and actuator jamming, avoiding production accidents caused by parameter loss of control.

4.3 Process Control of Steel Rolling Mill in Metallurgical Industry

In the control system of the rolling mill in the continuous rolling production line of the steel plant, the XVC722AE101 module is responsible for precise control of the rolling force, rolling speed, and steel plate thickness of the rolling mill. The module collects parameters such as roll pressure (pressure sensor signal), motor speed (encoder pulse signal), and steel plate thickness (laser thickness gauge signal) through the AI channel. After high-speed processing by FPGA and logical operation by microprocessor, the module outputs control signals to adjust the roll pressure and motor speed, achieving closed-loop control of steel plate thickness (control accuracy ± 0.01mm). The digital I/O channel is used to collect status signals of the rolling mill equipment (such as roll in place and normal hydraulic system pressure) and output device start stop and interlock protection commands, ensuring continuous and stable rolling process and improving steel product quality.

4.4 Urban heating network regulation system

In the intelligent regulation system of urban centralized heating network, the module can serve as the core control unit of regional heating stations, achieving precise adjustment of heating parameters and energy consumption optimization. By using AI channels to collect feedback signals on the supply/return water temperature, pressure, and user side room temperature of the heating network, and after internal fuzzy PID algorithm calculation in the module, the steam valve opening or circulating water pump speed of the heat station heat exchanger is adjusted through the AO channel to achieve dynamic adjustment of the heating amount, ensuring that the user side room temperature remains stable within the set range (± 1 ℃). At the same time, the module communicates with the monitoring terminal of the heating station through the RS485 interface, uploads operational data, and receives remote control instructions, supporting centralized management and energy consumption statistics of the heating system, improving heating efficiency and reducing energy waste.
