Small scada solution, supporting Modbus and Unitronics PCOM. Feel free to download UniGO from Android Market. Our idea is to do a quick visualization between an android device and a PLC system, it takes only minutes to set it up if you're used to scada. There is also an option for remote with buttons and input integers. All you need is of course a phone or tablet with the Android operating system and access to the internet. The software is optimized for communication with Unitronics PLC, but in principle is able to work with any device supporting Modbus IP/RTU, Modbus RTU with bluetooth.
