Hello Tom Ham customers have this weird tendency to dislike proprietary solution, moreso if they can't get local support for it and if it ties them to the OEM for support. So before you go and spend time and money on developing one, perhaps this may help: S7-1200's SD cards can be programmed in in a normal SD card capable reader (unlike the S7-300 MMC's which require a Siemens PG or Siemens USB Prommer). S7-1200's SD cards can additonally be used as either a so called "Program" card (i.e. permanent part of the CPU) OR as a so called "Transfer" card (i.e. used purely to "download/transfer" the program frpm the SD card into the internal load memory of the CPU without the need for the TIA portal software, see chapter 3.4.3 of the 1200 manual for more on this). I also know that you can at least view the contents of an S7-1200's SD card with Windows Explorer. What I don't know is if Windows Explorer can be used to simply copy a 1200 program onto a 1200 SD card (I don't have TIA portal nor a 1200 SD card and can't test/verify this) Let's assume itis possible, you could do the following: You use your TIA portal to create an empty SD transfer card and supply this ONE SD cardtogether with the (up to) 20 S7 1200 PLC's to the customer. You also give him a CD with all 20 odd S71200 programs on it. If one of the 1200's requires replacement, the customer takes the empty SD tranfer card, uses any Laptop/PC with an SD card reader and simply copiesthe correct 1200 program onto it using Windows Explorer. As said before, you (or someone out there) will need to verify if it is indeedpossible touse Windows Explorer to copy a 1200 program onto an SD "Transfer" card. Food for thought anyhow and I hope it helps |

Dear Fritz... Are you sure thatthe SD card can be programmed with a normal SD card reader. Regards. Tomy. |

Hello Tomy Master as sure as one can be who has NOT tested this himself, but instead received this info directly from Siemens during a (2 day agonisignly long) S7-1200 release seminar/workshop (which took place a couple of weeks when they were finally introduced into the Australian market and all I could think of was "where's my STL"). I most certainly did watch the Siemens Presenter usingWindows Explorer to "explore" the contents of an S7-1200 formatted SD card with his Laptop (mind you, he could have tricked me since all I did was asking "where's my STL"every couple of minutes or so, which wouldannoy even the most seasoned presenter). Note though that the question if its possible to tranfer the S7-1200 program onto the SD card with Windows Explorer issomething that I do not know and which someone else out there may be able to test and answer. |

Now this problem can also be solved by using theSiemens "S7-1200 Tool" |
