Tablet HMI comes in different sizes and operating systems, such as Android, iOS, and Windows. Depending on OS used, an internal application must be used to accommodate different communication protocols in terms of PLC makes and their networks. Downtime Reduction Group is using several solutions presently available for the tablet/smart-phone deployment.
  • All screens on the tablet HMI are developed pm the WEB server attached to the PLC
  • Some of the screens are developed using tablet’s applications, such as HMI Droid Studio.

HMI Droid Studio

Panels are created quickly and easily using the development tool HMI Droid Studio that runs on Windows PC as shown below:

Connections (symplified)

Media player or PC with Android-x86 in a local network

HMI android wi-fi wifi plc pjone tablet touch smartphone pad modbus/tcp rtu LAN media player

Communication over ethernet between a media player or a PC with HMI Droid and the PLC either directly (eg Modbus/TCP or Siemens S7 Communication) or through a serial port via a port server (eg COMLI or Modbus RTU).

  • Link preferences should be set to Wi-Fi, or Ethernet UDP when using SattBus COMLI.
  • HMI Droid can be used e.g. with WiFi PLCs from XLogic Sweden. (Select protocol Modbus/TCP class 1.)
  • Port server tested with HMI Droid and works well is MOXA NPort 5110 .
