Hello lalit; Step 7 Basis is the basic programming software for the S7-300 and S7-400 PLCs. You get all the basic tools, including programming software in STL, LAD and FBD. Step 7 Professional is a package that provides, along with Step 7 Basis, additional programming and debugging tools: -S7-SCL allows complex functions to be programmed in a Pascal-like platform,ideal for table and loop manipulations and mathematical calculations. -S7-Graph allows the development of sequential state-machine programs, based on the Grafcet standard; very good representation of machine operations. -S7-PLCSim is also provided, so you can debug your program without having a real PLC during development. You can look at the following link for more details on the Pro version: https://mall.automation.siemens.com/WW/guest/index.asp?aktPrim=0&nodeID=5000906&mlfb=6ES7810%2D5CC10%2D0YA5&aktTab=4&lang=en Hope this helps, Daniel Chartier |

ok. here is one morething, let's suppose if i create an application using pro, and use advance pascal tools to create some blocks,fc,fbs. will i be able to use basic version to troubleshoot those blocks, fc, fbc? is plc sim free with pro?

Hi, Yes, S7-PLCSIM is part of Step 7 professional. When you create a block using S7-SCL, you can not look inside this block, when you only use Step 7. Best regards, Wizard |

Also, it will not be possible to watch S7-Graph blocks. |

Hello, in fact it is possible to monitor the blocks (and you'd rather not to change), but just in the STL codewhich is compiled from these editors. The compilation from the SCL is more applicable for monitoring, the Graph compilation isn't continuous and issplitted so the monitoring there isless usable. Regards Sydney |

Watch a S7Graph - Block as AWL -codemakes absolute no sense! |

If it made no sense, it wouldn't work, don't you think? There could be found the steps and their code, as well as the transitions, anyway the monitoringthere isn'tso useful as I already wrote... Regards Sydney |

I think I understood from the above answers, I am almost clear about what I wanted to knew. however I would still keep this one open until someone else comesup with much more differences. Thanks

??? Just have a look at dchartiers answer up in this thread. Hardly to do the answer more detailed... Good look! |
