Technical Specification

Direct control and monitoring via the web — from the local network or Internet, from any platform — mobile device, tablet, laptop, workstation, etc., simultaneously from different locations, with no limit on the number of users
On-line Development Environment, available immediately after the device is powered on, no restrictions on the number of tags or licenses for additional software modules.
API to communicate directly with the user applications. Full support of the popular industrial protocols, ability to use different protocols on the same physical line and add custom protocols.
Built-in interface editor: built-in editor that runs in a web browser, allows to create visual GUI similar to HMI or SCADA systems, with text elements, vector graphics, animation, trends, historical graphs, messages, text entry fields, etc.
Access control: different level of access can be granted for different users as well as access restrictions to specific dashboards (screens)
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 through the same physical RS-485 line.
Custom protocols: for non-standard or not supported devices, using scripting language Lua, user can add program code to send and receive protocol telegrams.
Data exchange optimization: possibility of assigning different priorities to end points, 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 provide data exchange possibility between automation devices (PLCs, remote I/O, etc) connected to WebHMI.
Custom API: using API calls, WebHMI can directly exchange data with any business or user applications, other websites 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
Notifications: receive notifications via SMS, Viber or Telegram messaging
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)
