  • Publication number: 20230342184
    Abstract: An object of the present invention is to provide a SCADA web HMI system that can reduce a load for processing input/output signals in a large-scale system. An HMI server apparatus performs three filtering processing. In first filtering processing, in a case where received block data corresponds to a screen currently displayed on a web browser, a set of input/output signals is extracted from the received block data. In second filtering processing, input/output signals each having a value varied from a previous value are extracted from the set of input/output signals extracted in the first filtering processing. In third filtering processing, input/output signals corresponding to display parts arranged in the screen currently displayed on the web browser, are extracted from the input/output signals extracted in the second filtering processing.

  • Publication number: 20230307698
    Abstract: An all-solid-state battery includes a laminated body in which a positive electrode layer, a sulfide-based solid electrolyte layer; and a negative electrode layer are laminated; an absorber configured to absorb hydrogen sulfide gas; and an outer package configured to form a housing space in which the laminated body and the absorber are housed. The outer package includes a sealing portion configured to hermetically seal the housing space. The sealing portion includes a fragile portion whose sealing strength is weaker than that of the other portion of the sealing portion. In a case where the hydrogen sulfide gas is generated in the housing space, sealing of the fragile portion is released earlier than the other portion to form a discharge port through which the hydrogen sulfide gas is discharged to an outside of the housing space.

  • Publication number: 20230280724
    Abstract: The SCADA web HMI client device runs a plurality of web browsers communicating with a web server. A first web browser is displayed on first monitor and draws an HMI screen for monitoring and controlling an industrial plant. A second web browser is displayed on a second monitor and draws the HMI screen. An operation right table is obtained from the web server. If, in the operation right table, the first web browser is not permitted to operate the HMI screen, an operation part positioned on the HMI screen of the first web browser is drawn in an inoperable state. If, in the operation right table, the second web browser is permitted to operate the HMI screen, the operation part positioned on the HMI screen of the second web browser is drawn in an operable state.

  • Publication number: 20230259087
    Abstract: An object of the present invention is to provide a SCADA web HMI system that can reduce a load for processing an alarm signal in a large-scale system. An HMI server apparatus performs buffering processing and alarm filtering processing. In the buffering processing, in a case where a received block data includes a set of alarm signals, at least the set of alarm signals included in the block data is temporarily stored in an alarm buffer memory. In the alarm filtering processing, the set of alarm signals stored in the alarm buffer memory is taken out for every second period that is longer than a first period, and the alarm signal having a value varied from a previous value is extracted from the taken-out set of alarm signals.

  • Publication number: 20230251624
    Abstract: A drawing creating device generates HMI configuration data for a system monitoring screen from a network configuration diagram drawn by drag-and-drop operation. An HMI server device executes a system monitoring process by applying HMI configuration data to a predetermined server runtime library, and transmits a display signal according to the communication status of a monitored device. An HMI client device draws the system monitoring screen on a web browser and changes the display statuses of the parts positioned on the system monitoring screen according to the received display signal. According to the present invention, the system monitoring function of an industrial plant can be implemented in a non-programmable graphical manner.

  • Patent number: 11720082
    Abstract: A SCADA web HMI system dynamically distributes server connection priority lists from web HMI servers to HMI clients in accordance with order of assignment which takes load balancing into account. As a result, preliminary settings associated with connection priority do not need to be made on the HMI clients. Also, since the server connection priority lists are assigned to the HMI clients in accordance with the order of assignment which takes load balancing into account, the numbers of clients connected to the individual web HMI servers are equalized and the load balancing can be ensured. The SCADA web HMI system can reduce the operating costs necessary in client settings while ensuring redundancy and load balancing of servers.

  • Publication number: 20230236584
    Abstract: When a general-purpose operation part (22, 23) is hidden by a window part (24), it becomes hard for an operator to visually check an association state between a field device (10A, 10B) and a hardware switch (3). If such a display state has occurred, an HMI server (5) stops a health check signal which is being output to a PLC (6). The PLC (6) detects the stop of the health check signal and forcibly cancels the association state between the field device (10A, 10B) and the hardware switch (3). Thus, a human error can be prevented.

  • Patent number: 11606022
    Abstract: The insulation deterioration monitoring apparatus comprises a computer on which software is installed. The software causes the computer to execute at least first to fourth processes. In the first process, during stopping of at least one inverter unit, the computer selects one inverter unit out of the stopped inverter units and causes the inverter corresponding to the selected inverter unit to generate a direct current voltage. In the second process, the computer measures the current value of the ground current while the corresponding motor driving inverter generates the direct current voltage. In the third process, the computer records the measured current value of the ground current for each inverter unit in association with the selected inverter unit. Then, in the fourth process, based on the measured current value of the ground current recorded for each inverter unit, the computer analyzes the tendency of insulation deterioration of each inverter unit.

  • Publication number: 20220390934
    Abstract: A SCADA web HMI system generates an integrated component by grouping components including a first component and provides a first animation effect to the integrated component. The first animation effect is applied to the integrated component as a whole but not individually applied to components constituting the integrated component. The system provides a second animation effect to the first component. The second animation effect is applied to the first component but not applied to the components constituting the integrated component except for the first component. The system associates the first animation effect with the value of a first PLC signal and changes the appearance of the integrated component according to the value of the first PLC signal. The system associates the second animation effect with the value of a second PLC signal and changes the appearance of the first component according to the value of the second PLC signal.
