The new firmware version 2.0 for Simatic S7-1200 CPUs features Profinet IO Controller functionality, enabling communication with Profinet IO devices. The integrated web server, with customizable web pages, allows users to access CPU information and process data via a standard web browser. It also includes a history logging function for saving user program data at runtime.
Two new communication modules are available for connecting S7-1200 controllers to Profibus. The CM 1243-5 module, a ProfibusDP master, allows up to sixteen DP slaves, such as Simatic ET 200 modules, to be connected to the Simatic S7-1200. S7 and PG/OP communication with other controllers, as well as with HMI (Human Machine Interface) devices and programmers (PG), is also supported. The CM 1242-5 allows the Simatic S7-1200 to operate as a Profibus DP slave, for connection to any Profibus DP master. Both communication modules are installed to the left of the CPU and communicate easily via the S7-1200's internal bus.
The new CP 1242-7 Module, TeleService Adapter IE Basic, and TeleService GSM Module enable remote access to Simatic S7-1200 controllers. Any distributed or remote station equipped with Simatic S7-1200 can now be monitored, diagnosed, maintained, and controlled cost-effectively. Simply connect a CP 1242-7 GSM/GPRS interface to the Simatic S7-1200's internal bus to gain full remote control functionality. The TeleService Adapter IE Basic and the TeleService GSM Module are available for remote maintenance and diagnostics (Teleservice). To take advantage of these new telecommunication services, simply sign a standard SIM card contract or a special M2M (machine-to-machine) contract. With an internet connection and a programmer or PC running Step V11 engineering software, the user then has full remote access
to the controller. This wireless access allows for the detection and resolution of errors and faults at the remote station from the central monitoring station.
