Mr. Freddy Martens at ATS, Cogent's sales partner in the Netherlands, has found an easy, Java-based solution for putting real-time data from industrial processes into a mobile phone or other Android-based device, using the OPC DataHub. He has posted his story on the ATS TechLab blog with instructions for other Android developers to follow and links to download the software he used.
"This was surprisingly easy," said Freddy. "It just took a few hours of coding and editing XML files. I used the OPC DataHub and its Java API for the data connection, and the Android SDK examples to develop the front-end. A beginner Java programmer could also do this within half a day."
The resulting application lets a user enter the name of any process variable in his system into an Android cell phone and receive a live value that updates in real time. "On the ATS TechLab blog we have written the necessary steps, followed by a few examples," said Freddy. "The example code is easy to read and well documented. That should be enough to get started on this and similar Android development projects."
