I suspect 1. something wrong with your network. Are you using redundant ring or single ring? What is your network topology? 2. are you segregating terminal bus and plant bus? 3. any similar issues before? since when it happened? 4. any possibilities of IP conflict? 5. check your network node one by one to ensure all the IP are okay. |

1. What is the frequency of the errors? What is the time between failure? Is the failure happened in consistent timeframe? 2. check you take a picture at your netpro realtime connection detail? 3. check the wincc diagnose folder log, read all the log file, check any suspicious event? c:\program files\ siemens\ wincc\ diagnose. 4. How many network adapters do you have for your OS servers? 2 network adapters or 4 network adpaters ? 4 network adapters means -> plant bus -A, plant bus-B, Terminal bus -A, terminal bus -B. |

The error happened only one time and now resolved? check on the station with the client and server stations. How you do your redundant terminal bus and redundant plant bus? are they in standby redundancy or using PRP? |
