ABB LDGRB-01 3BSE013177R1 Control Unit Microcontroller

ABB LDGRB-01 3BSE013177R1 control unit’s main function is to configure the function of the radio frequency module and communicate with it to obtain the radio frequency module to obtain the radio frequency tag information, will obtain the tag information through the communication interface uploaded to the upper computer, but also can receive the upper computer on the radio frequency reader configuration instructions. Also, the radio frequency reader also need to leave a direct communication with the computer interface, in favour of the host computer software design and development.

ABB LDGRB-01 3BSE013177R1 needs to select the control unit microcontroller according to the functional requirements of the control unit and implement various communication interfaces. Here, the control unit is a microcontroller system with AT89S53 as the core, the microcontroller chip contains 12K Bytes of Flash Memory and 256Bytes × 8 RAM, three 16-bit timer/counter, nine interrupt sources, programmable serial UART channel, SPI interface.

The ABB LDGRB-01 3BSE013177R1 communication interface unit can be subdivided into two parts: the chip-level bus interface unit (M8 module supports I2C, SPI, UART, etc.) and the fieldbus-level interface unit (RS232, RS485, CAN bus, etc.). The control unit configures the RF module and reads the RF tag information captured by the RF module through the chip-level bus interface unit.
