Help For PC PLC Communication........

B]I am having network of 4 PCs, 4 PLCs and one server.
I want my server to read PLC Signals and send the information to respective PC.
Is this possible?
If so, will tcp/ip is useful or DDE service is ok?
I want VB(PC)-VB(PC) communication as well as VB(PC)-PLC communication.
I am doing PC-PLC communication using RsLinx

Thanks for reply.

I did the same exact thing but I used OPC from VB to do this.

I don't know if you managed to figure this out yet but the key in your case would be to use RSLinx Gateway. Have all of your VB apps connect to a "Server" running RSLinx Gateway, then the "Server" can connect to all the PLCs
