When you start PLCSIM you select PLCSIM(ISO). Try then. |

HiVispute Prashant, Thank you very much. Can you please explain more about virtual backpane/softbus and when we will be using that type of connection. If possible please send a manual.

dear all, the Named connections works only with the PC Internal Local mode of interface. In this mode, the PC station which is configured for the project acts a virtual communications gateway. the address of the recieving CPU as well as the address of the recieving OS station is determined by the station manager. The PCS7 OS, AS and ES communicate only to the station manager defined interfaces via logical addresses. Hence, this cannot be realised in a PLC SIM environment, as the AS cannot be addressed by the Station manager. The PLC SIM can only simulate the S7 module functionality, but not replace the modules themselves. This is the reason. |

Hi Saravana kumar, Ofcourse!!! The documentation as such for "virtual backpane/softbus " I did not found anywhere but by experience I can try to explain you. Let us consider the classic example of theAS Redundancy. InAS redundancy, assumeES & OSare having two CP1613 for example. In such case the tags in OS shall be under Named connections. The time you try to take online in CFC ofcourse you can use ISO for that matter. But in such case, if there is switchover of CP by any chance then you need to define the MAC address for the connection and all those stuff you need to do. Inspite of ISO if you set PG/PC as Local, in this case even on CP switchover you can monitor the values in CFC uninteruptly. The moral is, the Local can be selected in case we wish it to communicate with Simatic component in PG/PC. The PLCSIM is Tool which interpretes thedata framesas per your selection of the PROTOCOL e.g. TCP/IP, ISO, PROFIBUS, MPI, Local, etc and understands the Medium of communication. I hope that should clarify your Q. Best Regards, |
Prashant VISPUTE |

I completelty agree with Prashanth. In addition, I would like to expand on his example to clarify some of the points in my previous post. Our H systems are a classic example of simultaneous synchronised processing. This is important from process control availability point of view, but not for testing. Hence the PLC SIM does not provide any H station type functionality. It will only simulate the cyclic code execution and emulate H/W resources like timers, counters and I/O. That said, it must also be observed that we need to define a cpu access node whenever simulating any project. This eliminates any logical module addressing ( cpu, cpu etc... not to be confused with I/O modules and IM's). Now consider a case where there are 1 or 2 CP 1613 cards available and we deal with an H System. As prashant said, a switch over of the CP/CPU cannot be tested. also, in this case, the statiion manager would eveluate the diagnostics of the CP's involved and decide on which CP1613 must be used for data communication. all this cannot happen with PLC SIM. |

Hi Prasanth , Shankar, Thank you very much for your reply. As per your suggssion I have selected PLC SIM local, But I was not able to download the program. Is it needed to download the connection in Station Manager or is there any other way to do that. If possible please send a manual for using Local mode with PLC SIM and H-system with PLC sim.

Dear saravana kumar, it is not possible to simulate a complete H station with 2 CPU's which are redundant and synchronised. With PLC SIM V5.4 SP4, 2 different AS can be simulated simultaneously, allowing you to test AS-AS Communication and the rest. Again, the "LOCAL" type of interface must be used only when working with an actual AS. the tags can be switched from one connection to another in the SQL server. so switch the tags from named connectiosn to ISO and test your program. Once checked, you can switch the tags back to named connections. |

Dear sir , I am not able to connect PLSIM with PCS 7 using TCP/IP After following all standard steps in wincc the ststus of driver communication (s7 program) shows disconnected .. So can any one plz help me for that ? is there any manual for the setting to communicate PCS 7 to PLSIM ?? Thanks in advance... Shruti

it isnt possible use plc sim with name coneection, you have to do compile the project in another kind of connection maybe in ethenet, and then in the win cc project in the the system mangement in the conection for example industrial ethernet, system parameters change to PLC SIM, and work the PLC SIm in the OS |
