Title:
SCADA WEB HMI SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/182373
Kind Code:
A1
Abstract:
In the present invention, a SCADA web HMI system draws an HMI screen including a first rolled part disposed in a first zone and an extensible second rolled part disposed in a second zone. The first rolled part and the second material part are drawn in each drawing period, which is shorter than the PLC signal receiving period. The first rolled part tip position is calculated on the basis of the conveying speed and elapsed time included in the first PLC signal in each drawing period from the time the first PLC signal is received. The size of the drawn first rolled part is set to the length from the entry side of the first zone to the first rolled part tip position. If the first rolled part tip position has not reached the second zone when the second PLC signal has been received, the size of the drawn first rolled part is set to the length of the first zone.
