3BSE020838R1 CPU module
ABB 3BSE020838R1 is a PLC (programmable logic controller) CPU module, as the “brain” of the PLC system, responsible for executing the control program written by the user, processing the input signal, and controlling the output signal according to the program logic.
It has the following functions:
Data processing: able to handle a variety of digital and analog data, arithmetic operations, logic operations, data conversion and other operations.
Communication interface: Provides the ability to communicate with other devices or systems, may support a variety of communication protocols, such as Modbus, Profibus, EtherNet/IP, etc., to achieve data exchange and remote control.
Storage function: The ability to store user programs, data and system parameters to ensure that data will not be lost in the event of a power outage or other failure.
Diagnostic function: Monitors the operating status of the system, detects faults, and provides diagnostic information to help users quickly locate and solve problems.
Scalability: As a modular PLC component, it may support connection and expansion with other functional modules (such as input/output modules, communication modules, etc.) to meet more complex control needs.
