Hi, in Step 7 TIA V14 it´s possible to simulate a communication with PUT/GET but only over integrated interface of PLC - not over CPs. Check the following FAQ: How do you simulate communication between two CPU modules?Regards, Towome |

Hello, which version of PLCSim you use? Look at Chapter 7.2 of the PLCSIM V14 manual to see, which plc could communicate each others. https://support.industry.siemens.com/cs/ww/de/view/109741755 |

Hello kattus a physical S7-300 requires usage of FB14/15 GET/PUT blocks which are though NOT supported by PLCSIM. The trick is program your S7-300 as if it is an S7-400 and directly use SFB14/15 GET/PUT blocks and it will work (just make sure to change the program back to use of FB14/15 when you want to use it in a physical S7-300). |

New question published by vuvinh11 is split to a separate thread with the subject What should configure in program when call FB14/FB15 and to use as SFB14/15?. Best regards |
