An international energy standard based on the Common Industrial Protocol architecture can help you reduce energy use quickly and cost-effectively.
We've heard the numbers before: Manufacturing consumes more than one-third of the global energy used annually. Plus, it's one of the largest contributors to indirect costs. If we all understand the challenge, why haven't manufacturers done more to reduce energy consumption?
The fact is, with no uniform method to measure, report and control energy consumption, it's one of the most difficult costs to manage. At the same time, implementing an energy management system often requires significant application-code development, and might duplicate the existing control structure.
As a result, manufacturers see energy-improvement projects as too costly and time consuming to implement.
To respond to this challenge, Rockwell Automation is participating in groundbreaking work with ODVA to develop an international energy standard based on the Common Industrial Protocol (CIP™) architecture, called CIP Energy. Following are the five most important reasons to leverage CIP Energy to help manufacturers solve their energy management challenges.
- CIP Energy is an Extension of the No. 1 Industrial Ethernet Protocol in the World
The specification for CIP Energy is based on the protocol at the heart of EtherNet/IP™, which shipped 4.5 million nodes through the end of 2011 according to ODVA estimates.
In fact, the ARC Advisory Group's latest Industry Ethernet-based Devices Worldwide Outlook report confirmed EtherNet/IP's market position. The study indicated that the highest percentage of all industrial Ethernet nodes shipped worldwide are EtherNet/IP devices. That means you can take advantage of a common-command interface and network-visible data structure based on a protocol you — or someone in your plant — already knows and understands.
- It Can Help Save Money
Many energy-management projects require separate systems and metering equipment to gain visibility into energy usage. However, these systems often don't meet the required two-year or less payback period required by many businesses and, as a result, energy-savings projects receive a lower priority.
With CIP Energy embedded directly into existing Rockwell Automation Integrated Architecture™ systems, manufacturers can avoid installing a separate energy-management system. That helps reduce project implementation costs and creates a more feasible ROI timeline.
- CIP Energy Can Help Save Time and Effort
Energy management solutions often require significant resources and effort to install, including outside specialists to configure and program the system. With CIP Energy, manufacturers can significantly cut down on installation and commissioning time to develop an energy-monitoring and conservation solution.
Why? Because the energy data is now transmitted transparently over the network. This helps eliminate the need to design, document, test and debug special code in the controller to extract and format the energy data.
For example, in a trial application of the technology in an energy management solution, system-configuration time dropped from 80 hours to just two hours by using CIP Energy.
- It Helps Visualize Energy Consumption
If a manufacturer is conducting any machine or production process-level metering at all, it's probably performed by a separate system. Personnel likely aren't reviewing the data collected in real-time, either. That means manufacturers are either losing or considerably delaying meaningful and timely insight into energy usage.
CIP Energy makes energy data available over the network. It provides easy access to energy information, and allows greater visibility into energy usage at the operational level for easier baseline data creation.
This helps optimize energy usage during production and diagnose potential problems with the specific machine or process. For example, awareness of energy use at the equipment level might reveal an opportunity to automate equipment shutdowns when not in use to reduce unnecessary energy consumption.
- It Allows Manufacturers to take Advantage of the Smart Grid
With CIP Energy, manufacturers can begin to manage and optimize energy use at the machine, process and plant level, which provides a foundation for transacting energy with utilities.
For example, manufacturers can optimize tariff arrangements or demand-response programs with utilities and aggregators by taking advantage of tight integration between energy information and plant operations.
