The SIMATIC WinCC Sm@rtClient App, in combination with the SIMATIC WinCC Sm@rtServer, allows remote mobile operation and observation of SIMATIC HMI systems over Industrial Ethernet/WLAN (wireless). The app offers support for WebClient on Unified Panels, expanding accessibility through browser-based interfaces. It also supports WebView-based access to legacy webpages on PLCs, enabling users to access View of Things (VoT) pages. The app is available for SIMATIC HMI Comfort Panels, SIMATIC WinCC Runtime Advanced, SIMATIC Unified Panels, and PLCs. The scope of the Sm@rtClient concept allows an operator station to make its display available to the app. The station takes on the role of a Sm@rtServer, while the smartphone or tablet acts as the Sm@rtClient. Sm@rtServer functionality can be easily enabled with a single mouse click in the device’s configuration settings. The screen can be displayed on the Sm@rtClient in "View only" mode, or a full-fledged, coordinated operation can be set up. Coordinated operation ensures that only one user has control at a time — either the operator station with Sm@rtServer or the Sm@rtClient app. Additionally, the app supports easy connection setup through automatic HMI panel detection. The Sm@rtClient app not only shows the selected HMI screen but also mirrors the complete device layout, including functional hardware buttons. This enables users to interact with the system as if they were physically present in front of the panel — except buttons are triggered via touch input on the mobile screen. Functions: * Access to operator stations for the operation and setup of large, spatially separated machines * Flexible solution for safe and location-independent access to operator stations * Global access to plants (e.g. for service or maintenance staff) * Full access to hardware buttons on your Comfort Panel * Easy discovery of available Sm@rtServers * Coordinated operation through active remote control * View-only mode for passive monitoring * Support for WebClient on Unified Panels for browser-based access * Support for WebView-based access to legacy webpages on PLCs, enabling access to View of Things (VoT) pages

The SIMATIC WinCC Sm@rtClient App, in combination with the SIMATIC WinCC Sm@rtServer, allows remote mobile operation and observation of SIMATIC HMI-systems over Industrial Ethernet/WLAN (wireless). The app is available for SIMATIC HMI Comfort Panels and SIMATIC WinCC Runtime Ad-vanced. The scope of the Sm@rtClient concept allows an operation station to make its display available to the app. The station takes on the role of a Sm@rtServer, while the Smartphone/Tablet takes on the role of the Sm@rtClient. Sm@rtServer functionality can easily be activated with a single mouse click in the device’s configuration settings. The screen can be displayed on the Sm@rtClient by means of a Sm@rtClient display in "View only" mode, but a full-fledged, coordinated operation can be set up as well. "Coordinated operation" implies that at any one time only one user has the right of operation, i.e. either the operator station with Sm@rtServer function or the Sm@rtClient app. Additionally the app supports easy connection configuration by automatic HMI panel detection. Not only does the Sm@rtClient app show a selected display, but it additionally shows the complete layout of the station device, including any functional hardware buttons on the device. As such, device operation may be performed as if the user was directly in front of the device, only that the buttons aren’t actually pressed, but rather are activated with a press on the display of a Smartphone or tablet.
