5. Connections between the stations themselves via a local Ethernet network are not DNP3
connections. The connections are configured as S7 connections.
Access to the CPU data of the DNP3 station is configured using the TD7onTIM objects of
the TIM. Data is exchanged using the PUT/GET services.
The connection mode of the Ethernet interface of the TIM in DNP3 station 3 must be set
to "Neutral".
