MD741-1 GPRS router

The MD741-1 GPRS router has an RJ45 interface and permit data transmission using the GPRS - and EGPRS service (EDGE: 4 to 5 times faster than GPRS) of a GSM mobile radio provider both for the SINAUT ST7 telecontrol system and other Ethernet-based automation devices, e.g. for remote maintenance. Since data transmission from the GPRS provider to the control center or maintenance center is frequently implemented over the Internet, the MD741-1 has an integral VPN router and firewall. This allows bidirectional IP connections with optimum security to be established between the station and control center/maintenance center.

• Use with SINAUT ST7
  In a station, the MD741-1 is connected to a TIM communication module with Ethernet interface and a permanent connection to the control center is established. The TIM handles the transmission of process data based on changes, events and/or time. Operator inputs from the control center can be received at any time via the bidirectional connection and forwarded to the process. As counterpart of the VPN router in the station, a SCALANCE S module (S612 or S613) is used in the control center.
  
  
• Use with other applications
  Used for other applications, e.g. remote maintenance. Remote programming, parameterization and diagnosis can be performed securely via VPN from a maintenance center that is connected over the Internet to machines and plants installed worldwide. All the automation devices connected to the Ethernet port of the MD741-1 can be accessed. For additional information, see SIMATIC NET Configuration 9
