I am having trouble communicating my s7200 to my PC using MPI/USB adapter. But when i try to communicate using USB/PPI there is no problem. I don't know what is wrong, i have checked my PG/PC interface, I changed my baud rate to the available one's,there are three of them, (19.2kbps, 187.5kbps and 1.5Mbps) all of them did not work. My local connection is connected to USB.
I don't know what is wrong, could someone help me, thanks in advance, i will really appreciate your help, this will help me in my studies and for our defense. As you can see I'm still a student.
It works, but with newer CPUs only (I think firmware 2.XX)
But MPI minimum speed is 19,2, and S7-200 port is factory (default) configured to 9,6.
So you first need a PPI cable to change system parameter PORT SPEED to 19,2, and then, if firmware is 2.XX, you can use MPI cable.
If you work with Siemens equipment, I strongly reccomend you to have a PPI/RS232 cable, it is usefull also for transfering application and OS to a HMI devices.
Yes, it works as a PPI with s200, just change the interface settings. I use it as a MPI and PPi cable. But it wil not work as a PPI with firmware updates for panels.
