Read full description

The free JUMO Device app allows smartphones and tablets to communicate with the paperless recorder JUMO LOGOSCREEN 600. The app can scan for devices in the company network and displays the discovered devices in an easy-to-read list. Users can select the device either from this list or do so manually by entering the IP address / DNS designation. If a JUMO device is selected via the app, the device tells the app which data it can provide. This data could, for example, include current measured values, events, or alarms. The JUMO Device app also supports the automation system JUMO mTRON T (as of version 249.03.05), the process and program controller JUMO DICON touch (as of version 266.02.03), and the modular multichannel measuring device for liquid analysis JUMO AQUIS touch (as of version 304.02.08). The paperless recorder JUMO LOGOSCREEN 600 is supported as of version 323.01.01.
