I can do the communication with only one S7-400 and S7-300, but I can’t do the configuration of 3 S7-400 communicating with the S7-300 on NetPro. When I try to do the configuration on NetPro of the second S7-400, the follow message is showed “No valid connection could be established between the local and remote partners (for example, due to incomplete network or there are no more connection resources)”. What’s wrong in my configuration? Thanks.

In such a case the communication over networkborders is not possible. If you have a multi-project you have to interconnectall the networks within STEP 7. Is it possible that you use Repeater? May you provide, if possible, a screenshot ofyour NetPro configuration? Best regards J_Bell
