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, |
