DNP3 telecontrol protocol 21
DNP3 - example of secure TCP/IP-based connection over Internet via DSL (star topology)
DNP3 - example of redundant telecontrol connections (point-to-point topology)
TCP/IP-based WAN media
• Ethernet networks, e.g. SCALANCE X with fiber-optic
cables
• Industrial Wireless LAN with SCALANCE W
• Public networks and the Internet using DSL and/or GPRS
To permit redundant data transmission, outstations can be
connected to the SIMATIC PCS 7 TeleControl center over two
paths.
