Save energy with Profienergy during production breaks

The Siemens Industry Automation Division (www.siemens.com ) is now launching its first Profienergy products on the market: the Simatic ET 200S PM-E RO power module for the Simatic ET 200S High Feature distributed I/O system, and function blocks for Simatic controllers.The power module specifically switches off individual inputs and outputs of the ­Simatic ET 200S High Feature I/O system and disconnects their connected loads from the power supply.

 With the new function blocks it is possible to implement energy management of entire plant sections. They are based on the new Profienergy profile of the Profibus International (PI) and the new I device (Intelligent Device) Profinet functionality that permits

I/O communication between one CPU and other higher-level or central controllers. These function blocks take into consideration any automation structures with ­Simatic CPU 315-2 PN/DP, CPU 317-2 PN/DP and CPU 319-3 PN/DP controllers and Simatic ET 200S and ET 200pro distributed I/O systems with CPU functionality.

The vendor-independent and device-independent Profienergy profile standardized according to the PI enables individual devices or even entire sections of a production plant to be shut down without external hardware using a single controller via Profinet communication. Loads are switched off during production breaks in a coordinated fashion from a central location while other automation components are able to remain in operation, for example for safety-related tasks. At the end of the break the loads are then switched on again in a co­ordinated manner.
