copyright (c) 2010 Stefan Rudbäck, Matematica, , matematica.se sid 8 Date: Matematica/Example 2 If You want the massflow in a system with a magnetic volume-flowmeter You have to do the following calculation; flow(kg/h)=flow(m3/h)*density(kg/m3). Simplified first order code often calculates density linear as a function of temperature. This can lead to an error of several %! Matematica Lib calculates density with 0.01% uncertainty including pressure_impact

copyright (c) 2010 Stefan Rudbäck, Matematica, , matematica.se sid 9 Date: How can this be realized? In 3 steps; 1. The knowledge/math is ”on the shelf”. 2. Computers like PC/control system are also ”on the shelf”. 3. The knowledge/math are moved from the bookshelf to the computers without compromises.

copyright (c) 2010 Stefan Rudbäck, Matematica, , matematica.se sid 10 Date: Why? Because calculation errors often result in; 1. Waste. 2. Poor quality. 3. The production cannot be developed in an optimal way.

copyright (c) 2010 Stefan Rudbäck, Matematica, , matematica.se sid 12 Date: Processline The software which makes new software/function blocks for control systems. Processline is the tool you need to design your production site as good as possible at your desk. Output from Processline as standardized code will save time and errors for You.

copyright (c) 2010 Stefan Rudbäck, Matematica, , matematica.se sid 15 Date: Ex; With Processline You can: 1.Identify flow calculation errors. 2.Eliminate the errors with better code. 3.Automatic generate the code with a click on Procesline Kodfabriken/Bigblock Tag 4.Build a ”blindtarm” (dead end) that works side by side with the old code (if any). 5.Put the new code to work when it’s proven stable. Point 1-5 can reduce calculation errors from sometimes >10 to < 0.01%.
