1 copyright (c) 2011 Stefan Rudbäck, Matematica,+46 708387910, mail@matematica.se, matematica.se sid 1 Date: 110502 1.Processline (matematica_processline_110502.ppt) 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.

4 copyright (c) 2011 Stefan Rudbäck, Matematica,+46 708387910, mail@matematica.se, matematica.se sid 4 Date: 110502 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%.
