Odrid HMI is an alternative to traditional SCADA systems and operator panels. The app supports multiple data types and has easy navigation between panels (pages) using swipe gestures or buttons.
Odrid HMI is also great to use for home automation with PLCs that have e.g. Modbus/TCP protocol is implemented to remotely control and monitor lighting, ventilation, heating etc in the residence or holiday home.
Excellent technical support.
Graphic HMIs with multi touch function can be created in minutes.
Free-of-charge 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.
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.)
Numeric variables can be displayed as predefined text for example alarms, sequence steps etc.
Detailed diagnostics of connection and communication.
Variable areas for system variables, local variables and constants.
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 Baltic, Central European, Chinese (GB2312, BIG5), Cyrillic, Eastern European, Greek, Hebrew, Japanese (Shift JIS), Turkish, Vietnamese and Western character sets.
Ability to test run panels (pages) in the development tool.
LED-objects can be displayed as rectangles and in any size e.g. for Andon-systems.
Background color for panels (pages) can be selected.
Modbus Device ID can be changed with GUI objects during operation.
Floating point and hexadecimal number formatting.
Timestamp for panel (page) files.
Document information in panel (page) files.
Implemented protocols in the current version:
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.
Siemens S7 Communication: Reads and writes 8192 bytes in datablock 1 to 4095 and in the Input, Memory and Output areas.
(Default value for highest Siemens S7 databock is 255.)
Free-of-charge development tool for creating the panels (pages) to be used by Odrid HMI:
Modbus and Modbus/TCP are registered trademarks of Schneider Automation Inc.
S7 and STEP 7 are trademarks of Siemens AG.
Support for Vietnamese character set.
Bug fix for writing strings with reversed byte order using Modbus.
The Slider object is disabled if the connected variable does not have a valid value.
Improvement for System register R64542 (S7 DBNO) when using the Siemens S7 Communication (ISO-on-TCP) protocol.
Minor changes in the Button and Input field objects.
