Thin Client vs Thick Client for SCADA
IGX SCADA was designed for thin client architecture from the ground up, to be exact, it’s a Browser Server architecture that open to run with any standard web content natively. As a comparison, most traditional SCADAs was created as a thick client, or even without supporting any remote client by default. Usually these thick content is heavy and have difficulty to transmit through when you have network latency issue.
Unlike these traditional SCADAs that developed plugin, download, extension or any kind of thick client as a workaround to publish the proprietary content, IGX developed additional thick client for different purpose altogether. The sole reason is to protect the mimic workstation from being abused for any other purpose when designated workstation is needed.
Since the reason of existence is very different, to help you with better understanding, below is a comparison table for thin client vs thick client for IGX SCADA.
