Frequently asked questions

FabyaVision is Fabyatek’s SCADA / HMI software. You design a project in Studio and run it in Live; Convert turns TIA Portal HMI projects into FabyaVision projects. All three install on your own Windows computer.

There are 480+ 2D and 430+ 3D object types, all drawn in code as vector and 3D graphics. 420+ of the 3D objects have a detailed Realistic model besides the Standard one. Objects with a run / fault state, such as pumps and motors, change color and move with that state; for the others you bind the properties to tags yourself.

FabyaVision is Windows software that you install on site; there is no cloud service or mobile app. There is no redundancy (hot standby) or server / client architecture either, and Live runs one project at a time. Linux and macOS are not supported.

By default it runs for 30 days, and each session lasts 15 minutes; before closing it asks whether to save your changes and, if you don’t answer, saves and closes by itself. Studio, Live and Convert share the same number of days. Write to us if you need a different period.

The limit is time, not features. When the period ends the program no longer starts; your .fvs project files stay in your own folders. The demo is for evaluation; production use needs a license.

We don’t publish a price list on the site. For a license and a quote, describe your need (plant type, PLCs to connect, approximate number of screens and tags) on the Contact page with the “Request a quote” subject.

Yes. Sign-up asks for your name, e-mail, password, company and sector; the data is processed for the purposes in the Privacy Notice (KVKK). Consent to commercial messages is optional.

Windows 10 and 11. Windows 7 / 8, Linux and macOS are not supported.

.NET Framework 4.8 and the Microsoft Edge WebView2 Runtime are required; the installer installs them if they are missing. Because the prerequisites are bundled so they can be installed offline, the file is several hundred megabytes (the current size is shown on the Download page). 3D needs a graphics driver with WebGL support. If the automatic installation causes trouble, you can install both from Microsoft by hand.

The installer is not digitally signed, so SmartScreen may show a “Windows protected your PC” warning. Compare the SHA-256 value on the Download page with the one you calculate yourself; if they match, continue with “More info” › “Run anyway”.

Full, Field (Live only), Engineering (Studio and Convert) and Custom (you choose the components). Live is a normal desktop program, not a Windows service; to have it start with Windows, tick the option in the installer (off by default).

8 protocols: Siemens S7 (S7-1500, S7-1200, S7-300/400), Modbus TCP, OPC UA (client), Allen-Bradley EtherNet/IP, Mitsubishi MC, Omron FINS, OPC DA and MQTT. A built-in simulator lets you work without a PLC. Details are on the Connectivity page.

No, FabyaVision is an OPC UA client: it reads and writes data on another OPC UA server (security mode None, Basic256Sha256 signed or signed and encrypted; anonymous or user name / password). It does not offer its own data as an OPC UA server.

Yes. The simulator driver generates sine, ramp, square, random and counter signals and needs no network address. The sample project that comes with the demo also runs on the simulator. Before connecting real devices, we recommend a trial with your own PLC.

Yes: PUT/GET access must be allowed in the PLC and “Optimized block access” must be off in the DBs. Symbolic or optimized blocks are reached through OPC UA. PLC passwords and S7 secure communication are not supported.

No. All drivers work over Ethernet / TCP (COM / DCOM for OPC DA). There is no Modbus RTU / ASCII, PROFIBUS, MPI or serial Mitsubishi / Omron connection.

It reads the WinCC HMI devices in your TIA Portal V20 project (classic Basic / Comfort / Advanced, WinCC Unified and WinCC Professional) and converts screens, tags and connections into a FabyaVision project (.fvs). It does not write to the TIA project. You open the result in Studio and edit it. Details are on the Convert page.

No, the result is a starting point. Each object is marked “full”, “approximate” or “placeholder” in the report, and what could not be transferred is in the Warnings list. Font sizes and pixel positions are not identical; optimized DBs have no absolute addresses, so those tags arrive without an address. Animations and events do not run in the preview.

Reading directly from TIA needs TIA Portal V20, and your Windows user must be in the local “Siemens TIA Openness” group. We still suggest working on a copy of the project. Options without TIA: a ready-made export package or, for WinCC Professional only, the project folder.

No. The FabyaVision script engines use names similar to WinCC (such as HMIRuntime.Tags) but cover only a subset; HMIRuntime.Alarms, Logging and DataLogs are missing. Review and retest converted scripts. WinCC Unified JavaScript modules are carried over as source and not executed.

It depends on the family. For WinCC Unified, alarm classes and discrete / analog alarms are transferred. For classic HMI, alarm definitions, recipes, users and archives are not transferred; for WinCC Professional, alarm definitions are not. The report lists what was left out.

Four: VBScript, JavaScript, C and Python. The product’s own engines run VBScript, C and Python (no Windows Script Host, C compiler or CPython needed); each is a subset of the language, and Python has no async, networking or third-party packages such as numpy. JavaScript runs in WebView2’s own environment.

Only if you allow it. The “Connect to databases”, “Run programs” and “Access files” permissions are off by default and are turned on in Live Settings. JavaScript scripts have no database, file or program access. Scripts run only in Live.

Yes: the script editor has 120+ ready-made examples in four languages, a Reference panel, live syntax checking and a “Compile” (F9) command; compiling also checks project-dependent rules such as a missing tag or a call whose permission is off. There are no breakpoints or step-by-step execution.

Live opens a small web server on the computer it runs on (8080 by default); you watch the same project from computer, tablet and smart TV browsers. Monitoring is read-only: control, alarm acknowledgement, recipe or report actions and setting changes cannot be made from the browser.

There is authentication: user name and password, a session cookie, a temporary lockout after repeated wrong attempts and, by default, an access rule that admits only local network and VPN addresses. There is no HTTPS; the connection is plain HTTP, so do not expose the server directly to the internet and use a VPN. TV addresses have no password by default (this can be turned off).

Monitoring is done in the browser; there is no mobile app. There is a layout for narrow screens.

Users belong to groups, groups get numbered permissions, and permissions can be used at object, page and menu level. Passwords are stored as salted SHA-256 hashes. Operator actions (who, when, which tag, old and new value) are written to the log by default. There is no central directory connection such as AD / LDAP.

Connection passwords are kept in a plain-text file in the .veri folder next to the project (the OPC UA password is not written to the project file). Restrict access to that folder with Windows user permissions.

On the Contact page choose “Technical support”, “Request a quote” or “Partnership / integrator”, or write to info@fabyatek.com.

Yes. The English and Turkish manual installs with the software and opens with F1 in Studio; 100+ topics with screenshots. You can also read it in the browser on the Documentation page.
