#Hannover New Components for Controlling and Monitoring Plants via Remote Access

New modules and UMTS routers extend the range of solutions offered by the Siemens Industry Automation Division in the field of remote access. The two new modules TIM 3V-IE DNP3 and TIM 4R-IE DNP3 enable controllers of the Simatic S7-300 and S7 400 series to be controlled and monitored over different communication networks, such as the mobile network. The modules support the open DNP3 protocol, for communication with the control center. Extensive diagnostics functions are available to users, including logging the sent and received message frames. It is also possible to program S7 controllers that are connected to the modules remotely over an IP-based network, which reduces the number of costly on-site service visits.

The new UMTS routers Scalance M873 and M875 have been designed for remote access solutions in classical teleservice and telecontrol applications. Communications between the control center and the routers take place over the UMTS mobile network. They are also suitable for more complex applications, such as video transmissions. Scalance M875 also features a VPN function (Virtual Private Network) and a firewall. Due to the integrated security functions, Scalance M875 supports the protected connection of distributed automation cells to a control center over the mobile network. Scalance M875 can also be implemented in the context of Siemens Remote Services. This comprehensive service allows companies to commission Siemens with the monitoring, control and maintenance of distant plants and machines via remote access.
