  • Patent number: 10775762
    Abstract: A data converter, a signal transmission method, and a signal transmission system for transmitting a signal to a programmable logic controller are provided. The data converter: performs sampling multiple times with respect to data detected by a sensor in one communication period of communication with a programmable logic controller; acquires statistical data by statisticizing a plurality of sampling data in the one communication period; and transmits the statistical data to the programmable logic controller when the one communication period is reached. Therefore, a signal sampling density is improved, and thus control accuracy can be enhanced. At the same time, a data transmission amount of a bus is reduced, a load on the programmable logic controller is reduced, and user convenience is improved.

  • Publication number: 20180231950
    Abstract: The embodiments of the disclosure provide a monitoring method, a monitoring module, and a mobile terminal for monitoring a programmable logic controller (PLC) connected with one or more monitor targets. The mobile terminal is connected with the PLC, receives selection information input by a user for selecting a target component for the monitor target from a target component list, determines the target component based on the selection information, and associates the target component and the corresponding monitor target based on first input information input by the user. In an aspect, the mobile terminal receives data about the monitor target transmitted by the PLC, and the corresponding monitor target displays a status of the monitor target based on the data. In another aspect, the user is able to control the PLC through the mobile terminal.
