Creating an Industry 4.0 environment

Hardware is essential for Industry 4.0 components. But the real challenge lies in the software. SSV Software Systems has taken on both.

The architecture of Thinglyfied. While web pages are transmitted via HTTPS, MQTTS is used to transmit measured values. Each time the value is changed, the server sends the data via MQTTS without being asked, whereas a web form would first have to be requested via HTTPS.

With the DIL/NetPC DNP/9535, SSV Software Systems has developed an Industry 4.0-capable computer module based on an ARM Cortex-A5 with 528 MHz clock speed and 256 MB RAM. An embedded Linux with special extensions is located on the integrated MicroSD card in a lockable slot. The Docker container software Thinglyfied DC 1.0 is supplied as an external accessory. This provides easy-to-configure communication connections to other Industry 4.0 modules and any cloud platforms. In addition to a database, the Docker container has two proven cloud service standard interfaces, the SSV RTDC (Real Time Data Channel) and SSV HDC (Historical Data Channel). The external connections are made via the Cloud Connector Driver (CC Driver). Various plug-ins are available for this interface, which support practically all common cloud and IT platforms (MES, CRM, ERP). RTDC, HDC and CC Driver together form the SSV Embedded Cloud Services.

When developing the hardware and software, SSV was guided by the Industry 4.0 reference architecture model (RAMI 4.0) of the VDI/VDE Association for Measurement and Automation Technology (GMA). The Docker container serves as an Industry 4.0 administration shell and stores the data of the virtual representation for the DNP/9535 as well as the respective sensors, actuators and control functions of an application. DNP/9535 and Thinglyfied DC 1.0 have a standardized web interface for configuration in the application environment. Node RED serves as the basis in both modules, so that the required interfaces and data flow can be simply clicked together with the help of pre-installed function blocks via a web browser. Additional functions can be imported via the web interface.
