Operator panel for various industrial control system. Communication over Wi-Fi or mobile internet with the protocols Modbus/TCP (Class 0 and 1), Modbus RTU class 1 and Siemens S7 Communication (ISO-on-TCP).
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 eg 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 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.)
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 Greek, Turkish, Baltic, Central European, Eastern European, Cyrillic, Japanese (Shift JIS) and Chinese (GB2312, BIG5) 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 Slave 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 development tool for used to make the panels (pages) to be run by Odrid HMI:
Modbus and Modbus/TCP are registered trademarks of Schneider Automation Inc.
S7 and STEP 7 are trademarks of Siemens AG.
Button objects with the Toggle flag button action does not invalidate any polled variables.
The About-dialog displays the slide show mode time.
New datatype BYTE in the Numeric variable, Slider, Bar Indicator and Radio button objects.
Support for offset in the LED-object for Modbus Holding and Input register extending the bit address range from 16 to to 20 bit.
New directive $align="right"; for controlling alignment in the Numeric variable object.
Four new system registers in the Siemens S7 Communication protocol driver.
Bugfix in the Siemens S7 Communication protocol driver.
Support for dark mode in iOS 13 or higher.
Optional scaling and centering of panels (pages).
The app can be installed on a Mac.

HMI for iOS
This is a very simple and highly effective HMI for iOS. I looked for years for something simple, quick to setup, and cost effective. So far, this is the best. Very reliable communications drivers. For the price, there is enough functionality. The support is immediate and accommodating. I needed an enhancement done to the scaling routine and it was ready and released in a couple of weeks. I am using this app to allow operators and maintenance people to remotely read a critical water tank level and backup power IO for a small town public water system.
