introduction：When setting up the control system， System integrators invariably want to achieve more with fewer devices。They need control systems that can handle more than just numbersI/OSum movement，Visual functions and modular instruments for automated monitoring and testing can also be integrated。In addition，The control system must also be able to process control algorithms and analysis tasks in real time and transmit data back to the enterprise。Market research companyARCFirst adopted by consulting agenciesPACThis term，It defines a new type of controller，The controller combinesPCProcessor of、RAMAnd the advantages of software，andPLCInherent may
