WAN
(Wide Area Network)
Data network with a large geographical span, such as the Internet. telephone or enterprise
networks.
The following WANs can be used with SINAUT:
● Classic WAN networks
SINAUT communication is possible via the following networks:
– Private or leased dedicated lines
– Analog telephone network
– Digital ISDN network
– Private wireless networks (directional or omnidirectional wireless and private mobile
wireless with time slots)
– Mobile wireless network
A classic WAN is connected via suitable transmission device (modem) to a serial
interface of the TIM.
● IP-based WAN networks
SINAUT communication is possible via the following IP-based networks:
– Over wireless by using special wireless systems optimized for Ethernet, for example,
the components of a SCALANCE W IWLAN system
– Via fiber-optic cable, for example in conjunction with SCALANCE X switches with
optical ports. This allows distances of up to 70 km to be covered.
– Over public networks and Internet with DSL or GPRS
– Private wideband systems such as OTN, PCM30 etc.
An IP-based WAN is normally connected to an RJ-45 interface of an Ethernet TIM via an
Ethernet-compliant module (see section "Installation guidelines").
To allow use of GPRS, the serial interface of a station TIM 3V-IE can be connected to a
GSM network via the GSM modem MD720-3. This requires the MSC protocol to be
enabled in the STEP 7 > Properties dialog of the TIM > "Interfaces" tab. The WAN
interface then behaves like a virtual Ethernet interface.
WinCC
WinCC is a cross-branch and technologically neutral system for the solution of visualization
and process control tasks in production and process engineering. It provides function
modules for graphics display (Graphics Designer), for signaling (Alarm Logging), for
archiving (Tag Logging) and logging.
WinCC API
As a completely open and expandable system, WinCC makes a comprehensive API
(Application Program Interface) available. This involves an interface over which the user
programs such as ST7cc Server and ST7cc Config can access WinCC. A comprehensive
description is available with the WinCC ODK (Open Developers Kit).
