英文摘要	The utility model discloses a PLC-based multi-point data acquisition device with controllable data flow direction. The device comprises an industrial personal computer which is connected with at least one PLC through a switch, every PLC is numbered with a unique number, and the number is a symbol to distinguish one PLC from another a thread pool is opened up for each PLC and the thread pools are used to process data communication of different PLCs the direction of data flow between the industrial personal computer and the PLCs is controlled every PLC can recognize their own number as well as the numbers of other PLCs, and the numbers are interpreted as IP addresses inside the PLCs during communication and each PLC is provided with two different ports used as a data transmitting port and a data receiving port respectively. The PLC-based multi-point data acquisition device with controllable data flow direction has the advantages that the direction of data flow is controllable, the flexibility is high, and the device can adapt to occasions with poor-regularity data collection point distribution.
