Optimising graphics for mobile devices

摘要

Scott Kortier examines best practices for interfacing mobile devices to automation systems through PC-based and embedded HMIs to provide the required access controls, security and viewing experience. With Mobile devices increasingly being used to interface to industrial automation systems - usually for monitoring but sometimes for remote control. The HTML5 standard found in many modern embedded and PC-based HMIs minimises the development work needed to publish graphic screens from an HMI to mobile devices such as laptops, smartphones and tablets. Although it is easy to publish graphics, the user experience may suffer depending on the type and size of the mobile device display.
