SIMATIC-based Power Data Management System

SIMATIC-based solutions for the process and manufacturing industry

Very high energy consumption levels are often encountered in the processing and manufacturing industry. It therefore makes sense to integrate a power data management system in existing systems.

Communication through PROFIBUS DP

PROFIBUS DP enables integration of a wide range of devices:

• For the protection of distribution boards and loads:
• protective devices, such as circuit breakers
• For control: frequency converters, motor management systems and soft starters
• For detection
  
  • electrical measured quantities: via the 7KM PAC3200/4200 measuring devices
  • non-electrical measured quantities: via analog/digital converters

PROFINET and PROFIenergy

An increasing number of devices in automation technology offer PROFINET. A 7KM PAC Switched Ethernet PROFINET expansion module is also available for the 7KM PAC3200 und 7KM PAC4200 measuring devices.

PROFIenergy is a "Common Application Profile" from the PNO. Thanks to PROFIenergy it is possible to assemble an power data management system with standardized device interfaces.

Function block libraries for SIMATIC PCS 7 and WinCC

The function block library for SIMATIC PCS 7 and WinCC ensures device integration as follows:

• Measured quantities and states can be connected via CFC.
• Structured display of measured quantities and protection parameters for the 3WL/3VL circuit breakers.
• Limit value violations are displayed, archived and acknowledged in the relevant communications system in the usual way
• Circuit breakers can be program-controlled or manually operated with the appropriate user authorization

• Increased energy efficiency due to exact knowledge of the load profile
• Optimization of power supply contracts
• Assignment of power costs to cost centers
• Optimization of plant maintenance
• Identification of critical plant conditions
• Reliable monitoring of the power limit through automatic load management

The SIMATIC-based power data management system is used in all industries in which PCS 7 and WinCC are used, and the transparency and monitoring of power flows is crucial.
