Operator panel for various industrial PLC's. Communication over Bluetooth, WiFi or mobile internet with the protocols COMLI, Modbus/TCP (Class 0 and 1), Modbus RTU class 1, SattBus COMLI, Siemens Fetch/Write or Siemens S7 Communication (ISO on TCP). Can also run on stationary devices such as media player or Raspberry Pi and with cabled ethernet connection.
HMI Droid is an evolution of the HMI program LEDpanel for Windows and is a supplement or alternative to traditional SCADA systems and operator panels. It handles logical and numerical variables and has easy navigation between panels (pages) using swipe gesture or with buttons.
HMI Droid is also great to use for home automation with PLCs that have eg Modbus/TCP protocol is implemented to remotely control and monitor lighting, ventilation, heating etc in the residence or holiday home.
Excellent technical support.
Long expected life cycle.
Graphic HMIs with touch function can be created in minutes.
Free development tool with test run feature.
Virtually unlimited number of panels (pages), objects and variables.
Does not require any third-party services.
Genuine native app, not based on neither HTML nor OPC technology.
Parameters for communication such as IP address, port number, protocol, etc. can be specified per panel (page).
Automatic polling of all variables displayed in the current panel (page), no need for separate tag list.
Many formats for numeric variables such as 16 and 32 bit integer, unsigned, hex, ASCII, float (IEEE 754), etc.
Prioritized event-driven transfer to the controller.
Panels (pages) are edited in the measurement unit dp (Density Independent Pixels).
Life bit for monitoring the operator panel in the controller. (Function similar to coordination area in Siemens S7.)
Auto-scaling allows for using the same panels (pages) on smartphones, tablets and other devices.
Numeric variables can be displayed as predefined text for example alarms, sequence steps etc.
Detailed diagnostics of connection and communication.
Variable areas for system and local variables.
Possibility of automatic return to the start panel (page) after some time of inactivity.
Selectable order for high and low words of 32-bit variables in the Modbus protocol.
Poll interval can be set do save data traffic or battery.
Support for Greek, Turkish, Baltic, Central European, Eastern European, Cyrillic, Japanese (Shift JIS), Chinese (GB2312, BIG5) and Korean character sets.
Implemented protocols in the current version:
COMLI: Message 0, 1, 2, 3 and 4. Addresses register 0 - 3071 and flags 0 - 37777 (octal).
Modbus/TCP: Class 0, Function 3 and 16. Reads and writes 64,512 holding registers.
Modbus/TCP: Class 1, Function 1, 2, 4 and 5. Reads 65,535 discrete inputs, 65,535 input registers and reads and writes 65,535 outputs (coils).
Modbus RTU: Class 0 and 1.
SattBus COMLI i.e. COMLI SattBus over Ethernet.
Siemens Fetch/Write: Reads and writes variables in data block 1 to 255 between bytes 0 and 4095 and byte 0 to 127 in variable areas for inputs, outputs and memories.
Siemens S7 Communication (ISO on TCP).
Android 4.1 or later.
External storage must be available. (Not to be confused with SD Card.)
Windows PC for editing panels (pages).
