Features and advantages

Direct control and monitoring via the web — in a local network or the Internet, from any platform — mobile phone device, tablet, laptop, computer, etc., simultaneously from different locations, with no limit on the number of users

On-line Development Environment, which is available and ready immediately after the device power on, with no restrictions on the number of tags or licenses for additional software modules.

API to communicate directly with user applications.

Support for popular industrial protocols, with the ability to use different protocols on the same physical line, and to add custom protocols.

The devices can be used for supervisory control of distributed systems when they transmit data to the cloud-based system Level2.

Visualization

Built-in interface editor: built-in editor that runs in a common web browser allows you to create visual screens similar to the screens in HMI or SCADA systems, with elements of text, vector graphics, animation, trends, historical graphs, messages, text entry fields, and elements of recipe control.

Access control: different levels of access can be granted for different users as well as access restrictions to specific dashboards (screens)

Communication with the automation devices

Supported protocols:

• Modbus RTU/ASCII/TCP
• Delta Electronics DVP
• Siemens S7 Communication
• Siemens PPI
• Mitsubishi MELSEC
• Allen-Bradley DF1
• 1-Wire
• ОWЕN
• Carel Easy
• User-defined protocols

«Multi-protocol» function: ability to work simultaneously with different protocols on the same physical RS-485 line.

Custom protocols: for non-standard or not supported devices, the user himself can add program code to send and receive protocol telegrams, using a handy scripting language Lua.

Data exchange optimization: there are possibilities of assigning different priorities for communication to get faster response and speed for specific data, limiting scan time, and using block reads for faster data exchange.

«Any-to-any protocol» gateway function: using the built-in scripting language, you can easily implement data exchange between different (with incompatible protocols) automation devices connected to WebHMI, like PLCs, remote I/O, etc.

Integration possibilities

Custom API: using API calls, WebHMI can directly exchange data with any business or user applications, other web-sites etc.

ModBus TCP Server: a group of tags can be accessed by external clients like SCADA system, PLC or another WebHMI, via Modbus TCP protocol

Automated control

User scripts: user can write functions in popular scripting language Lua, for implementing fairly complex algorithms of data processing, schedulers, logic control (similar to PLC) etc.

Notifications

SMS, Viber, Telegram

Network capabilities

Built-in router functions: routing, firewall, NAT, and other features allow you to integrate WebHMI in any network infrastructure without additional network equipment

Wi-Fi interface: can work simultaneously in different networks, as a client and as an access point, WPS mode is also supported

VPN support: simple implementation of remote access to the system, without use of dedicated static IP-addresses.

NTP server/client: time synchronization via NTP protocol

Built-in support for 3G modems. Modem re-initialization by disabling USB power is supported too.

Remote service access: user can operate the equipment connected to WebHMI using service and development tools, via a virtual COM port and Ethernet (using the possibility of forwarding traffic over the gateway)
