Siemens upgrades Simatic S7-1200 controllers

March 10, 2016 - Siemens upgrades Simatic S7-1200 controllers with an Energy Meter module, firmware version 4.2 with backup/restore function, and a safety CPU.

The Energy Meter module SM1238 precisely records energy flows. For operators looking to branch out into the field of machine-related energy management, the SM1238 Energy Meter module is just 45 millimeters wide, and can be used to record energy flows simply and precisely, directly on the machine. The measurements are processed directly in the CPU, and visualized with an HMI (Human Machine Interface) system, such as a Basic or Comfort Panel. The SM1238 Energy Meter module records measured electrical values, such as voltages up to 480 V AC, 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 ampere current transformer with a conversion factor of up to 10,000 is used to measure the current.

The CPU 1212FC can be used for failsafe applications in the lower power range. The Safety CPU is able to handle standard and safety-related automation tasks, such as protective door monitoring, in a single device. This also reduces the wiring required in comparison to conventional solutions. Supporting Profisafe enables safety-related devices to be connected via Profinet - for example, the integrated safety functions of Sinamics drives can be used directly via Profinet. This also reduces wiring outlay, saves space in comparison to conventional safety solutions and allows more flexible safety concepts.

Firmware version 4.2 includes a backup/restore function for backing up project data for the 2-port CPUs 1215 and 1217. The firmware has been updated with the new version of the TIA Portal V14 engineering framework, and expanded to include additional functions. Version 4.2 includes the Media Redundancy Protocol (MRP) for the 2-port CPUs 1215 and 1217, increases network availability, and offers greater flexibility when it comes to network configurations, for example in ring topologies. This is rounded off with the backup/restore function for backing up project data with up-to-date values to prevent data losses.
