The machine executes intermediate universal code similar to an assembler, compiled in CPDev engineering environment from source programs written in control languages of IEC 61131-3 standard. The machine is implemented as a C program, so it can run on different target platforms. Data formats and commands of the machine code are presented, together with the machine’s Petri-net model, C implementation involving universal and platform-dependent modules, target hardware interface, input/output programming mechanisms, and practical applications.}, type={Artykuły / Articles}, title={Development and Implementation of IEC 61131-3 Virtual Machine}, URL={http://journals.pan.pl/Content/93628/mainfile.pdf}, keywords={multi-platform virtual machine, assembler, IEC 61131-3, programmable controllers}, }
