AndroidTM is not only the most popular operating system for consumer devices, AndroidTM is also becoming increasingly important in industry. Optimized for touch-based operating concepts, the operating system also opens up completely new application possibilities for machine operation and the trend is moving towards touchless and wireless devices. ACD Elektronik has developed its own, particularly secure AndroidTM version, the industrial-grade AndroidTM Industrial+ operating system, to meet the significantly higher requirements in industry about data security. The entire source code is stored on ACD Elektronik servers in Germany so that no data is passed on to third parties. In addition to the high level of data security, it also impresses with regular updates, upgrades and security patches.
As ACD Elektronik does not use a cable for its M2Smart® HMI devices, a major focus during the development of the devices was on ensuring secure data transmission even without the use of a cable. With the mobile devices from ACD Elektronik, data is transmitted securely via a radio link using the black channel method. Communication takes place between the HMI and a gateway connected to a secure controller. The devices can be easily paired via RFID and then the HMI panel, including the integrated emergency stop and enabling switches, is ready for use. Safety levels up to PLd are achieved by utilizing a two-processor architecture.
