Communication of the RTU3010C and RTU3030C with a master station TIM
Telecontrol with the "DNP3" protocol
The following example contains a configuration with stations that communicate with the
master via the mobile wireless network and the Internet.
In this example, the master is duplicated. The two devices of the DNP3 master (main and
substitute master) in the master station are addressed by the RTU using one DNP3 address
but two different IP addresses.
The connections between stations and master are via an OpenVPN server "SINEMA
Remote Connect".
When using the DNP3 protocol, for example, SIMATIC PCS 7 TeleControl or the system of a
third-party provider can be used as the master. If you use SIMATIC PCS 7 TeleControl as
the DPN3 master, you require the necessary DPN3 driver.
