Siemens USB PC Adapter firmware upgrade

[zer0net]

Hello everyone,
I have USB MPI+ cable v1.2 and my OS is win Vista ultimate I think i need to upgrade to v1.3 and in order to do that one end of the cable needs to be connected to the PLC and the usb to the computer, my question is that if to do this will it change any thing inside the PLC or no?

Thank you

As in all plcs firmware versus software has a certain lockstep.

I think there was a siemens matrix on compatibility of firmware and software for their plcs. I would post this on the siemens website, they would be better to give you an answer then here.

But as first glance I would not think the version of MPI firmware cable would make much different to the plc like the minor revision that you are stating. But I know siemens revisions were major when even incremented on a minor from 1.2 to 1.3.

Again post on siemens website or call their support.

Thank you

You'll need to upgrade the firmware inside the adopter, not anything on the PLC!

And I'm a bit confused why "one end of the cable needs to be connected to the PLC and the usb to the computer"?! Only the PC-end should be connected for upgrading.

Which PLC are you working one, BTW? S7-200? or 300/400?

You'll need version 2.0 for Vista, if you're using Simatic 5.4

Sorry for the late reply,
I am using S7-300. This cable I got from ebay, its not the original Siemens cable.
However I just realized that it does not support Profibus and my PLC and HMI are connected through Profibus. Anyone have any idea as to how to modify the cable to work with profibus?

Thanx

You seem to be confused. One version of Profibus is RS485-based, which, supposedly, should be the interface supported by your cable. Perhaps you should contact Siemens application support.

What are your objectives for using this cable? You originally indicated that you'll connect the PLC with a PC using this. Your PLC should have an MPI port besides the Profibus DP port. This cable will connect to that MPI port.

What is the part number of your S7-300 CPU?
