Spider PLC   Spider Web-Kit  Spider Cloud Portal

Do you want to program and visualize quick and easy?

Then just use the different building blocks of SpiderControlTM .


Automation components should be programmed, configured and operated exclusively via a normal web browser. In the age of IoT and Industry 4.0, PC-based tools are no longer up-to-date. iniNet Solutions provides the modular system to equip your product with comprehensive web functions.


So far, users have designed, programmed and visualized with a PC tool and copied the output to an embedded system with a Web-Server. Now all this works directly over the browser! This means that no PC software is necessary for the development because the entire software for the design of the user interfaces is provided by the embedded Web-Server.




Spider PLC 

Simple PLC functions!


With SpiderControlTM Spider PLC, embedded devices can be programmed directly using a standard HTML5 browser. In the age of the IoT it is necessary that intelligent devices can be programmed directly in the field. But it must be as simple as possible! The programming via the integrated Web-Server offers enormous advantages:

  • No software installation on the PC
  • Programming with smartphone and tablet
  • No download, no wrong software version
  • Seamless integration with the cloud (optionally, only if the customer wants it).


Spider PLC Programming: Select standard logic function blocks from galleries and connect them by drag & drop:

Visu elements can be integrated directly into the Spider PLC for debugging:

Compile / Run / Debug: A single button!

Debugger: More than just an insight into the process:


Spider PLC is a kit:

You want to have your own Spider Web-HMI Editor?
The functions and the user interface of the programming tool can be drawn and implemented using the SpiderControlTM PLC Editor (PC-Tool). Simple logic functions are programmed directly with the SpiderControlTM logic actions. For complex logic, external functions can be called from a block. You can integrate your own algorithms in C / C ++ or in IEC61131.


Take advantage of the easy-to-use HMI programming via browser!

Combine with web visualization: The Spider Web-HMI Editor is integrated and allows parallel design of attractive user interfaces.


Runtime requirements: 

The entire functionality is integrated into an embedded web server. This is available on all common operating systems:

  • Windows 7/8/10
  • Windows CE (WEC)
  • Linux
  • Raspian
  • Android

Due to its a portable and modular design, Spider PLC is also available on microcontrollers and RTOS.

Spider Web-Kit 

Use the user-friendly browser-based programming of SpiderControlTM !


With the Spider Web-Kit, you can replace your PC application with a browser-based application. So far, an automation equipment manufacturer had to develop a PC application for configuration and commissioning. This PC application would then be deployed together with the embedded systems.
The Spider Web-Kit allows for fully browser-based applications instead. Up to know, browser interfaces on embedded systems have been limited to functionalities known from classic human-machine interfaces, which are characterized by typical elements such as buttons, lists or trend displays. But to catch up with the functionality of PC based configuration tools, an application needs to offer the design of dash boards, the configuration of components by drag & drop, logical connections of components as well as to display of any kind of graphical plots. These and many other features are now available in SpiderControlTM . This makes SpiderControlTM no longer just a HMI tool, but a browser-based, graphical editor.


Easy configuration of different components via drag & drop. This system solutions can be developed quickly and easily.

Displaying any plots is possible in a simple way. No matter what application it is.

Drawing own dash-boards is done in the browser-based graphical editor directly on the PC and is intuitive and easy.

The programming can also be done worldwide via tablet or smartphone. Usability is the main focus.

Spider Cloud Portal

Benefit from our secure internet connectivity!


How to connect embedded systems easily and securely with the cloud?
If the embedded systems only send cyclical data to the cloud (one-way) it is simple: there are protocols like MQTT. But if you want remote access for programming, configuration, support, operation and maintenance – it will be much more difficult. Existing solutions with VPN tunnels are complex and expensive to install and operate. When dealing with many systems this becomes a huge cost factor.

iniNet Solutions offers a technology that can be easily integrated into any system, offers high security and low costs.


SpiderControlTM  VPI Internet Access is a patented concept for Internet access, which is hard to beat in terms of simplicity, in terms of installation and use. All operator pages and functions that can be used via HTTP protocol are made visible through a portal on the Internet, while maintaining high security standards.
This is especially true for embedded Web servers. OEM customers benefit primarily from a great transparency, which is represented on the Internet.


Technical information

The VPI Agent can be integrated directly to your PLC or to a device in the same network and needs only a few tens of kB of code. The embedded VPI agent is available for WinCE or embedded Linux and can also be ported to RTOS. The advantages of this concept are enormous:

  • No additional hardware (such as a VPN router) is necessary, all components run on the PLC
  • No public IP address required, the agent works with any Internet access infrastructure (prepaid GSM, public WLAN, …)
  • No modifications to the firewall, it is sufficient to have http access to the Internet
  • Most simple installation
  • Full encryption possible, etc.

The agent is written in the programming language “C” and can also be operated directly on small controllers. Thus, an embedded system independently maintains a connection to the Internet, without the need for a fixed IP address (or an IP address) or another device. The problems arising with DynDns with an IP address change are also completely eliminated. The embedded agent also integrates a symmetrical encryption, which requires little performance even on small platforms. Thus, this solution provides the optimum in terms of hardware, running costs and security.
In contrast to a connection with DynDns, the PLC is not simply visible via an IP address in the Internet, but via a virtual subdirectory of the portal server. This portal server is in a secure zone, communicates externally via encrypted connections, and manages users, passwords, access rights, and profiles in a central database. If necessary, certain functions can be specifically blocked in the portal. A log file of the user interactions (audit trail function) can also be implemented centrally.



This technology can be integrated into existing systems. On the embedded system, the VPI agent is integrated (a few kbytes of code), which communicates with the VPI cloud. These connections can then be used transparently from any cloud applications of the customer.
