Telecontrol communication over the wide area network is largely determined by the communication infrastructure which already exists. Various transmission media such as dedicated line, analog or digital telephone networks, wireless networks (GSM or private), DSL or GPRS can also be combined with each other.

DNP3 telecontrol protocol

SIMATIC TeleControl for WinCC V7.4 also supports the DNP3 telecontrol protocol. Widely distributed outstations (RTUs) can be controlled and monitored with the DNP3 telecontrol protocol via serial or Ethernet TCP/IP communication links by means of the telecontrol center in SIMATIC WinCC.

The control center integrated with SIMATIC TeleControl into the SCADA system is the master during telecontrol communication. The slaves are represented by the remote stations. SIMATIC S7-1200, SIMATIC S7-1500, SIMATIC S7-300/S7-300F and S7-400/S7-400F/S7-400H/S7-400FH controllers as well as RTU3030C and third-party RTUs can be used as remote stations.

Further hardware and software components round off the range of products:

• TIM communication modules
• TCP/IP converters – serial and MD modem modules
• Mobile radio components (GSM/GPRS)
• TCP/IP routers and switches
• SCALANCE S security modules
• Dedicated line accessories
• Cables
• Engineering package for configuration of DNP3 data objects, stations, networks and connections as well as for diagnostics

In order to implement telecontrol networks, basic topologies including point-to-point, multi-point, star and ring can be configured using classic or TCP/IP-based media. These can be combined flexibly depending on the existing infrastructure.

Classic WAN media:

• Dedicated line via modem, e.g. SINAUT MD2
• Private radio networks
• Analog telephone network
• Digital ISDN network
• GSM, UMTS, LTE mobile network

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
