Need pin out for 232 communication on Step 7 200

hello, can someone tell me what the pin out is for a communication cable that will connect from my laptop to the plc using a 232 cable. Thanks

PLC is RS485. You need to buy the cable from Siemens. They also do offer a USB version of that cable. I don't have the part numbers with me, but I can post them tonight.

Thanks, I do have an adaptor card and hardware adaptor for CP5512. My problem now is everyime I try to connect, I get a message that the port is being used by something else. I can not figure this out. I have the communications set on 5512MPI. Any ideas?

S7-200 is not MPI, it's PPI. MPPI is for the S7-300 and S7-400. S7-200 takes a different adapter than the big guys.

I figured it out and as I was going to post my fix, you verified what I discovered. Thanks for your help!!
