Relationship between driver connection name - PLC IP

[pablo.chamorro]

Hello,

We are trying to obtain a list of our S7 driver connections with the name connection and IP, we found that _S7_Config.IPAdress and _S7_Config.Connections.All use not a lineal relationship.

How the driver connection knows wich IP has to use?

In my test the entries in the shown DP elements match.
Do you get the correct information when opening the S7 panel and choosing one of the connections?
Did you do the configuration for the S7 connections using the panels or have imported an ASCII file and/or did you use an own script?

The dpe '_S7_Config.Connections.All' contains only a list of '_S7_Conn' datapoints. The value of the datapoint element '<_S7_Conn>.DevNr' should be the index in the '_S7_Config.IPAddress' list (and other dyn elements at this level).

Hi gschijndel,

I checked it, you are right.

Thanks so much!
