Software Services - SCADA and HMI Systems, Cimplicity, iFix Configuration

We specialize in identifying customers' core business issues and designing data collection systems that allow them to create visibility into their processes so as to best manage and control their operations.

Information Systems Survey

An initial audit of all existing automation and information assets provides the starting point for any successful Software implementation. Coupled with interviews with key staff to assess business requirements, we deliver a report outlining current strengths in your data systems and identifying possible risks or areas for improvement, with a suggested path forward to optimize information effectiveness.
Data Integration

Accurate and timely information is key for making major decisions in a manufacturing environment. Data collected from plant floor controllers and processes are invaluable to the operation of any manufacturing facility. Our engineers are experts at:

  • Making disparate SCADA and data collection systems communicate.

  • Eliminating the 'pen and paper' logging of data from the plant floor.

  • Integrating plant systems to ERP and business systems.

  • Applying tools to analyze plant-floor data.


Our team of engineers is versed in applying many of the leading software tools in the industrial market, including:

  • GE Intelligent Platforms's Proficy Suite

    • Statisical Process Control (SPC)

    • Overall Equipment Effectiveness (OEE)

    • Plant Historian

    • Web Portal

    • Plant Apps and MES



  • Intellution iFix

Proficy Cimplicity and Windows 7

Many of our customers have a corporate IT initiative to move to Windows 7.   In other cases they purchase new hardware and notice that Windows 7 is the only OS available.   Cimplicity version 8.1 provides full support for Windows 7.    Automatic configuration upgrades with Cimplicity are the best around.  We've converted version 3 to version 8.1 with no manual touch ups.

Don't get caught with an old system that is not easily replaceable due to hardware availability.  Older Cimplicity versions (4,5) typically run on Windows NT machines and versions 6 and 7 run on XP.   Both these platforms are hard to find these days, so in the case of a hardware failure, buying a new PC and simply re-installing existing software may not be an option.  The best option is to upgrade proactively now while the older system is still functioning and you can do a side by side migration.

Calculate Return on OEE Improvement

Overall Equipment Effectiveness (OEE)


Improving Production Performance

Manufacturing facility managers are always looking for ways to improve the efficiency of their production lines and identify bottlenecks in their operations. One of the metrics that managers can use to characterize the performance of their organization is Overall Equipment Effectiveness (OEE). Managers that examine data on their production performance in an efficient manner and can correlate events with causes in real time can gain more control over their operational procedures and ultimately increase the quality and performance of their facility.
What is Overall Equipment Effectiveness?

OEE is a factor that is used by production managers to evaluate performance and effectiveness of a process, whether that process takes place at a single workstation or across a complete factory. OEE takes in several individual measurable metrics and normalizes them in such a way that OEE can be compared to other production lines or even other industries. OEE is often used as a key performance indicator (KPI) for manufacturing operations, particularly those focused on lean manufacturing. OEE also allows companies to benchmark their individual manufacturing lines against other plants within their organization and across their industry.
How to Measure OEE

There are three basic metrics that are used to calculate OEE:

  • Availability - Availability is the percentage of time that a machine is available for operation. Availability is the same as “uptime”, and is calculated as a ratio of available time divided by schedule time.

  • Performance - Performance compares the operational speed of a machine to its designed speed. Performance is calculated by multiplying the number of parts produced by the ideal cycle time, then dividing by the available time.

  • Quality - Quality measures the percentage of quality or “good” parts out of the total part run. Quality is calculated by dividing the number of good parts created by the total number of parts created.


OEE is therefore Availability X Performance X Quality. So, if a machine has 95% Availability, 85% Performance, and 93% Quality, then OEE = 0.95 X 0.85 X 0.93 = 0.75, or 75%. Because it is nearly impossible to achieve a perfect OEE, as even small reductions are multiplied through the equation, a target OEE of 85% is a common goal for many manufacturing operations. However, many manufacturing operations are thought to have actual OEE levels of 40-50%.
Tools for Tracking OEE

While it is possible to track OEE through manual data recording and collection, it is far more efficient to automate this data collection. Manual data collection is more prone to operator error, so, OEE values calculated with manually collected data is less accurate than if it is calculated using data collected automatically. Manual data collection is also slow, and it takes time to gather and analyze hand-written or hand-entered data.

GE Intelligent Platforms's Intelligent Platforms' Proficy Plant Applications Efficiency is a tool that can help facility managers get a handle on their current OEE, and plan methods to improve OEE. Proficy Plant Applications Efficiency can automatically collect the data from each manufacturing line needed to calculate OEE in real time, so managers can monitor line performance from shift to shift, looking for disparities in OEE and implementing effective solutions. Proficy Efficiency allows manufacturing facilities to leverage their existing manufacturing and automation systems by connecting with many different kinds of applications.
Benefits of Tracking OEE

When a manufacturing facility deploys an OEE tracking system effectively, the facility can get a better handle on production and performance metrics. These metrics can help managers make faster and more informed decisions about optimizing manufacturing processes. Managers can track downtime, production levels, and waste, and can determine causes or effects of system events in real time, allowing them to respond faster, and in turn improve OEE. Performance can be compared shift by shift and hour by hour, or product to product.

If OEE can be improved, facilities can increase their profit while maintaining operational costs:

Profit = Plant Sales x Plant Gross Margin x % Increase in OEE

For example, consider a plant producing $10M in product sales per year with a plant gross margin of 50% and a plant OEE of 60%. If the plant can realize a 10% increase in OEE from efficiency software & focused performance improvement efforts, this would result in an increase in profits of $300,000.

By implementing an automated method for measuring OEE, such as GE Intelligent Platforms's Intelligent Platforms' Proficy Plant Applications Efficiency software, companies can identify and take action on negative factors such as equipment bottlenecks, unexpected downtime, and production losses caused by shortages in materials or resources. Manufacturers that identify these negative conditions and take action can increase equipment utilization rates, providing them with a distinct and sustainable advantage over their competitors.
