OSCAT Building
OSCAT Building v1.00 - Open source library with 57 functions for building automation is ported into Mosaic
We ported for you the open source library OSCAT Building 1.00. The library has 7 chapters and there are about 57 functions and function blocks. Documentation is available in english or in german. The library is supported in Mosaic from version 2015.2. The Building library is not the default part of Mosaic installation and it is necessary to add it manually in the Mosaic directory of libraries. Compiled library in format .mlb including all other relevant files can be downloaded here: OSCAT_Building_v1.00.zip.
OSCAT is acronym of „ Open Source Community for Automation Technology “. This community created Open Source Library - (Download) - based on the standard IEC 61131-3. The aim was to create the library which is not dependent on the funtions of the PLC manufacturers and is easy transferable to all PLC, which are compatible with the IEC 61131-3 standard . Description of the portation of OSCAT library for Mosaic in english is here. The community has its own web site www.oscat.de.
