• 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.
