Siemens Simatic S7-1200 Basic Controllers portfolio expansion

Siemens has added a range of modules and functions to the Simatic S7-1200 Basic Controllers. This includes the SM1238 Energy Meter module; the Safety CPU 1212FC for failsafe applications in the lower power range; and the latest firmware 4.2 version of the TIA Portal V14 engineering framework.

For operators looking to branch out into the field of machine-related energy management, the SM1238 energy meter module is a suitable choice. At only 45 mm wide, the module can be used to record energy flows precisely, directly on the machine. The measurements are processed in the CPU and visualised with a human machine interface system, such as a Basic or Comfort Panel. The module also records measured 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 Safety CPU 1212FC can handle standard and safety-related automation tasks, such as protective door monitoring, in a single device, reducing the wiring required in comparison to conventional solutions. Supporting Profisafe enables safety-related devices to be connected via Profinet, which also reduces wiring outlay, saves space and allows more flexible safety concepts.

Version 4.2 firmware has also been updated and expanded to include additional functions. This version includes the Media Redundancy Protocol (MRP) for the 2-port CPUs 1215 and 1217, increases network availability and offers greater flexibility for network configurations, eg, in ring topologies. Also included is a backup/restore function for backing up project data with up-to-date values to prevent data losses.
