The Siemens Industry Automation Division is expanding its TeleService (remote maintenance/diagnostics) and Telecontrol ranges with three new products for remote access by mobile radio (Fig.). The CP 1242-7 module adds a GSM/GPRS (Global System for Mobile Communications/General Packet Radio Service) networks interface to the Simatic S7-1200 controller. The Telecontrol Server Basic control center software can address up to 5,000 Simatic S7-1200 and Simatic S7-200 microcontrollers via the mobile radio network. The third innovation is the IE Basic TeleService Adapter with the TeleService GSM module for dial-up connections which facilitate the remote maintenance of a Simatic S7 by mobile radio. Remote access solutions from Siemens enable plants to be economically monitored, controlled and maintained from a distance. The technology also facilitates communications from machine to machine (M2M).
