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
