 WEBHMI is a solution that allows the user to effectively solve the task of monitoring the status of various engineering systems and facilities, as well as their remote management.

 The simplest application is a local operator interface for monitoring industrial automation systems and equipment. The ability to manage various devices from any computer, tablet or smartphone, through a web browser, from anywhere on the network or via WiFi. In this case, WEBHMI can integrate into an existing network or act as a stand-alone access point.

 ===== Remote HMI =====
 The option is similar to the first, providing access to the interface via the Internet, for monitoring remote objects. In the absence of communication channels, the most rational solution would be to connect WEBHMI to the mobile 3G Internet by simply installing the modem into the USB connector of the device. To access the site, you will need to obtain a static IP address from the provider or connect to an external network using a VPN.

 Finally, the variant of constructing a dispatching system for distributed objects, assuming a two-level topology in which WEBHMI acts as data gateways of the lower level, transferring information to a dedicated server that ensures its further processing and storage. For more information about this feature, contact your device vendor.

+===== Application target size =====
+Size means number of registes (tags or variables) in the process - usually the more tags the more screens, reports, control and other features demanding higher performance. Folloing are not strict rules but rather a "rule of thumb".
+  * Up to 2-3K (for single facility) - Hardware WebHMI version
+  * High demanging in terms of performance with 5-10K and more tags - Virtual box image. This image can be installed on a dedicated industrial single - board computer or box PC or on a customer's virtualization server.
+  * Large disributed applicatoin - Level2 together with WebHMI (of any kind)
+  * Small size applications, distributed IoT applications - Level2 cloud running virtual image.
+  * Educational and trial applications - any of virtual images with the respective license.
