S7-200 PLC's on a PPI network

[Electromechanical30]

Hello all,

I have a project that involves integrating several S7-200 CPU's. I have already looked at the help pages in S7 micro/Win. I tried linking an S7-226 to a S7-222 as an experiment, but I didn't get any result. I did use the NET_EXE wizard in micro/Win to configure the NETR and NETW commands on the master (the 226 CPU). I have the 226 addressed at the default, 2. The 222 is addressed as 3. I have the program on both set up so that the discrete IO is moved into a V memory byte(s), per the micro/win help...

I am using Profibus cable and connectors for the interface cable (port 0 on the 226 and port 0 on the 222). Could this be my problem? Is the profibus cable compatible with PPI protocol?

Any comments, further questions, and/or links to reference material is greatly appreciated.

Thanks!
