Siemens has added a range of modules and functions to the Simatic S7-1200 Basic Controllers. One of the modules, the Energy Meter module SM1238, records energy flows. In addition, the controllers have also been enhanced with an updated CPU 1212FC for failsafe applications in the lower power range. The firmware for the Simatic S7-1200 Basic Controllers has also been updated with the latest version of the TIA Portal V14 engineering framework, and expanded to include additional functions. The version 4.2 release now includes the Media Redundancy Protocol (MRP) and a backup/restore function for backing up project data for the 2-port CPUs 1215 and 1217.

The SM1238 Energy Meter expansion module can be used to record energy flows directly on the machine. The module records electrical values, such as voltages up to 480 VAC, in a 1- or 3-phase network with a direct connection but without a transformer. The user can freely adjust the diagnostic parameters for over- and undervoltage, overload, tolerance value and tolerance time. An external 1 or 5 A current transformer with a conversion factor of up to 10,000 is used to measure the current.

The firmware update increases network availability and offers greater flexibility when it comes to network configurations. The backup/restore function allows for backing up of project data with up-to-date values to prevent data losses.

The Safety CPU 1212FC is able to handle standard and safety-related automation tasks, such as protective door monitoring, in a single device, and now supports Profisafe.
