Hello List, I have several years in programming both PLC's and System Applications (C/C++). For the PLC's I have used all IEC 1131 languages and in the past Assembler, STL and LAD for older PLC's The last few years several PC-Based control vendors are promoting Flow Charts. I have tried some and have mixed feelings, what do you think Is Flow charting good for Interlocking?, State Machines? Step programs? What do you think of Decisions instead of Transitions in the classic language "SFC" are they good or clumsy? Can a PLC program be created with Flow Chart only or should Flow Chart only be used for specific parts of the program? Thanks, Ronald Nijssen
