Hello Derek; Good question! The mathematical data for the S5 and S7 PID controllers are hard to find; they rely mostly on diagrams to show how they are using gain-independant position PID controllers. Have a look at the implemntation of FB251in a S5-100U, you can compare the structure of the controller to that of a S7 CPU: http://support.automation.siemens.com/WW/view/en/1086289 Also, follow the following FAQ to helps you adapt the parameters of a S5 PID controller to that of FB41 in a S7 CPU: http://support.automation.siemens.com/WW/view/en/17991108 Hope this helps, Daniel Chartier |
