The Remote Operator mobile app for the Vision and Samba series is available from Apple's App and Google Play stores. The application enables users to access Unitronics controllers remotely using a smartphone or tablet. Via the app, they can view and operate the controller’s HMI as if physically touching the controller. It allows users to monitor automation processes, press keys, touch HMI objects, change parameter values, view alarms and process value trends, as well as define and access multiple controllers from a single mobile device.
