Help with Siemens S7-200

Please help;

Can i use the PC adapter ( MPI- serial converter) to connect my notebook to S7-200 cpu

Thanks

Mostafa

The communications protocol that a S7 200 uses is Siemens PPI (point to point interface) not MPI (multi-point interface) so I guess the answer is no!

You will need the PC-PPI interface cable, part number 6ES7 901-3BF20-0XA0

Paul,

that's entirely right. MPI works at 187.5 kbaud, whereas S7-200 (and thus PPI) is limited to 9600 or 19200 baud depending on the CPU.

Kind regards,

get the CP5511 if you have the cash. You can talk to the 200's , 300's, and 400's

Thanks guys for replaying but do not forget that S7-200 could be on a MPI network... So Why not?

Many plc's can be on many networks...that doesnt mean they can be programmed using that network interface.

Mostafa,

you're right about an S7-200 in an MPI network, but that's only to exchange data with S7-300's and S7-400's, not to program the darn thing.

I wonder why we would however use that possiblity, because it means we have to bring the speed of those rather expensive MPI-interfaces down from the normal 187.5 kbaud to 19.2 kbaud. It sounds to me like hiring a 20-tons trailer to get some bread in the bakery less than 1km away from home. Why not use those two long things below my body, I think we call them legs.

Kind regards,
