1.Processline (matematica_processline_110502.ppt)

The software which makes newsoftware/function blocks for control systems. Processline is the tool you needto design your production site as good as possible at your desk. Output from Processline as standardized code will save time and

errors for You.

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 Tag4.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%.
