Taking Siemens Support advice, I uninstalled and reinstalled MicroWIN. Upon attempting to communicate with the PLC, I get an error that is to the effect of "could not establish communication over PROFIBUS network. there may be another master on the bus. check addressing and cable." I am attempting to communicate through comm port 0, at 187.5 kBaud, and am searching all baud rates for a connection. any ideas? Brooks
