In a station for the S7-CPU, the communication module TIM 4R-IE DNP3 (TeleControl Interface Module) handles the data exchange with the assigned SIMATIC PCS7 TeleControl V8.0 master system using the open DNP3 protocol. In addition, the V3.0 module now also supports master and node functionality.

With the double-width S7-300 housing, the module can be fully integrated into the S7-300 system
Can be connected as a stand-alone module to a SIMATIC S7-400 and SIMATIC S7-400 H System
Two RS232/RS485 interfaces support connection of an external modem for data transmission via a conventional WAN or of a Modbus RTU slave to an S7-300 system
The module has two RJ45 interfaces for data transmission via IP-based networks
By using physically separate connection paths, the module permits media redundancy without loss of data during the switchover

Область применения

Low-cost automation of water/wastewater networks with both complex and simple structures
Control and monitoring of energy distribution systems and supply stations, such as oil, gas or district heating networks
Preventive maintenance (condition monitoring) of globally distributed systems
Connection of plants with basic or high-level security and availability requirements
Use in hybrid networks with wireless, Ethernet or Internet communications

Дизайн

The TIM 4R-IE DNP3 offers all the advantages of the SIMATIC S7-300 design:

Compact design with double-width S7-300 format
Two 9-pin sub-D connectors with a combined RS232/RS485 interface for connection to a conventional WAN via an appropriate modem
Two RJ45 sockets for connection to Industrial Ethernet or an IP-based network;
industrial design with additional retaining collar, for connecting the IE FC RJ45 Plug 180
2-pin plug-in terminal strip for connection of the 24 V DC external supply voltage
Front-panel LEDs for indicating the module status and the communication
Easy installation;
the TIM 4R-IE DNP3 is mounted on the DIN rail of the S7-300 and connected to adjacent modules by means of the bus connector supplied with the TIM. No slot rules apply.
For connection of an S7-400 station, it is linked as a stand-alone device via one of its Ethernet ports with one or more S7-400 CPUs.
Can be operated in the expansion rack (ER) in conjunction with the IM 360/361 interface modules
Can be operated without a fan
A backup battery and a memory module (C-PLUG) can be installed as options

Функции

Data is transmitted using the open DNP3 protocol
Media redundancy by the use of physically separated connection paths without the loss of data when switching over
Extensive diagnostics functions including the option of logging the sent and received message frames
Time-of-day synchronization with the assigned DNP3 master system is possible
Remote programming in the case of IP-based networks
Option for connecting a SIMATIC S7-400 and SIMATIC S7-400 H system
Modbus RTU Master connected to a serial port
Also available with the new Version 3.0
DNP3 Master
DNP3 nodes;
the module operates simultaneously as master and slave and, as a data concentrator, links the RTUs with the control center
Peer-to-peer communication in the Ethernet-based network between the TIM modules used as DNP3 slaves
Setting of DNP3 event classes (Class 1, Class 2 and Class 3)
Routing between TIM modules
Support of analog dialup modems (PSTN dialup)

The communications module TIM 4R-IE DNP3 has its own processor and a RAM for buffering up to 200,000 data points. This prevents any loss of data in the event of a fault on the communication link or the failure of a communication partner.

Diagnostics

The SINAUT diagnostics and service tool of the SINAUT ST7 Engineering Software V5.4 provides comprehensive diagnostic functions, including:

Operating status of the TIM module
Module status of the TIM module
General diagnostic information
Diagnostic buffer of the TIM module
Status of the connections to remote communication partners (e.g. SIMATIC PCS7 TeleControl V7.1 SP2)
Status and level of the transmit buffer
TIM frame monitor for recording the frame traffic

Configuration

The SINAUT configuration software V5.4 is used for configuring the TIM 4R-IE DNP3 module. Parameters are assigned with the aid of the SINAUT configuration software in STEP 7 HW Config and STEP 7 Netpro.

Интеграция

The TIM 4R-IE DNP3 module is connected to a WAN via two floating RS232/RS485 interfaces, and specifically via various data communication devices depending on the application:

Dedicated line modems for point-to-point, point-to-multipoint or line connections
Analog dialup modems (V3.0 or higher)
Fiber-optic cable modules (via RS485 converters)
Wireless devices from various manufacturers

In addition, it is possible to connect a Modbus RTU slave to the S7-300 system via the TIM 4R-IE DNP3.

Via two RJ45 interfaces, the TIM 4R-IE DNP3 module can be connected to the Ethernet, i.e. to IP-based networks (LAN, IWLAN, DSL, GPRS, UMTS, etc.).

Configuration examples in conventional and IP-based WAN

Use in a station with transmission via a dedicated line network

The connection to the master station is via the MD2 modem, which sets up the connection via a dedicated line.

Use in a station with transmission via Internet

The stations are connected by means of an Internet connection. In this case, DSL routers must be used in the station and control center – preferably in combination with SCALANCE S in order to establish secure connections using VPN tunnels.

Use in a station with transmission over the GSM mobile telephone service GPRS or UMTS

The stations are connected via the GSM mobile telephone service GPRS. In this case the GPRS router MD741-1 is used in the station and a SCALANCE S security module is used in the control center which ensures that the VPN connections are set up with the GPRS stations.

For higher data rates, in place of the GRPS router MD741-1, the UMTS Router SCALANCE M875 can be implemented for use of the UMTS mobile radio network.

Use in a station with path redundancy

The connection of the stations with a TIM 4R-IE DNP3 enables redundant connection paths to be set up. On the failure of the active connection (e.g. the Internet connection) a switch is made to the second connection path (e.g. WAN).

Особенности

High plant availability by means of end-to-end redundancy
Connection to DNP3 master systems from third-party vendors is possible by using the open protocol DNP3
Saving of traveling and maintenance costs due to cost-effective remote programming, diagnostics, control and monitoring via the Internet
Reduction in time and costs thanks to quick and user-friendly configuration of connections and data to be transferred with the SINAUT configuration software and block library
Reliable back-up of important data;
Storage of the DNP3 data points (max. 200,000 in the case of a master), including time stamp on the TIM if the communication path is faulty or a partner has failed
