Connection lost with CP 243-1

[mulderm 3]

Hello, I have a Siemens s7-200 plc (CPU222) and a CP 243-1 ethernetmodule. Most of the time when I will going online using MicroWin I get no connection with the CP 243-1 and sometimes I get good connection. When I going to the communications option and I click on the refresh than sometimes I get "unknow" adres and "not connected". The leds on the CP 243-1: Run and Link leds are green. When I using a ping command always I get response from the CP 243-1. The cable is correct. When sometimes I have connection (led cfg is yellow) then the communication stay's good. When I going offline and try online again then there is again no connection. Who recognise this problem? Greetings, mulderm

Sounds like a connection timeout issue. If you wait more than say 5 minutes after disconnecting, does it allow you back in? It just might not be timing out your sessions when you disconnect fast enough.

Change (Force) your PC ethernet connection speed to 10Mbps, you will get a very good connection quality.
