Simatic Performance Management Overview
In today’s world of fully automated production it can be difficult to turn process data into useful information. One way of doing this is by using Siemens WinCC Performance Monitor in conjunction with Simatic Information Server. In this series we will cover the basics of these tools their benefits, details on implementation, and how to quickly realize the ROI on your investment.
Turning Data into Information
Many manufacturing companies cannot easily assess the health of their plants. This is rarely due to a lack of data. Process Historians collect real-time data and can be used to show trends over time, quality control data can be compared to those trends and even some KPIs can be calculated for the process as a whole. This system breaks down when raw data is the only resource available to provide the necessary insight to answer questions about operations.
Data fails to take into account micro-level details affecting macro-level performance. For example, with raw data alone it can be difficult to determine which machines are causing the most downtime, where bottlenecks are in the process and where quality losses are greatest. Determining the top 10 causes of downtime would require first collecting all of the data in one location, summing the downtime for all pieces of equipment, and ordering the list. If you are lucky you might be able to get all of this done before the phone rings with some other distractions.
How do people find ways to track their process, find the major issues, and get them resolved? One way is to use performance management systems such as WinCC Performance Manager and Simatic Information Server. These type of systems take the process data you are already collecting and provide the context necessary for the data to be useful as a decision making tool.
Deciding to Do Things Differently
The decision to implement a performance monitoring system can seem daunting. The cost of buying the software, the time involved in configuring things, learning a new system and integrating it into your workflow. While there are some costs associated with the system both in terms of time and resources, these systems can have a direct impact on your bottom line. One simple is example of this is by using the tools to identify and reduce the top 3 reasons for downtime in your plant, thus automatically increasing productivity. Our customers have made similar gains by decreasing processing time by identifying bottlenecks and reducing re-work and scrap by identifying faulty equipment.
In this series we will focus on Siemens’ WinCC Performance Monitor and Simatic Information Server. We will answer some common questions about what these tools have to offer and discuss of the direct benefits our customers have found after using them. If you are looking at similar solutions from other companies, we will cover continue to cover those in later posts.
To summarize, performance management systems give you the ability to ask questions about your operation while at the same time giving you the information you need to answer those questions and prioritize improvements. They give you an honest assessment of your plant’s health. While this may be difficult to stomach, if your plant needs some help wouldn’t you want to know exactly what to fix to make it better?
