Instrument Control System Seminar, 20 th -24 th October 2014 Prelimnary Conclusions + Simple adaptation of existing code. + CPU consumption when running C++ modules is very low. + Opens the door for implementing more advanced applications. + Communication module to module via input/output is very simple. - Development environment (XAE) is not yet a mature product. - Some problems with Object Ids when exporting C++ code with methods called from PLC code. - Beckhoff documentation is still rather poor in many areas.
