Make your own Soft-SPS in only a few steps with an emtrion DevKit and freely available software from logi.cals. At first you integrate the logi.RTS runtime system into the RootFS of the DevKit. Afterwards you install the development environment logi.CAD 3 compact onto the host.
Now you can generate a SPS-application according to IEC 61131-3, load it onto the target and execute it. The integration of I/O-support can be realized by using emBRICK modules. logi.CAD 3 allows you to debug, step through the program and watch/set variables. Visualization is possible via a web interface.
