Way to make a bulk parameter change of user defined function blocks ?
Is there a way to make a bulk change of parameters of user defined function blocks in Freelance 9.2? In the export function of the Bulk Data Manager only the built-in function blocks can be selected.
I need to change some houndreds of measuring ranges and alarm points and I have to use the user function blocks from customer.
Thank in advance!
BDM option is not available with user define function blocks, But there is inheritance feature available with UFB so that if you change initial values of UFB variables, variables name or some internal logic to parent block/ UFB class then after plausibility check passed all the changes will automatically reflect in all the child instances used in different TASK/PL/FBD throughout the freelance project.
So in your case if you want to change measuring range and alarm points in UFB instances then make those changes in parent UFB class and child instances will follow those changes at several places.
Hope that helps to you..
Why do you think, that in excel you can do this work more quickly? If you need to change parameters than open project and do it )) In excel there will be the same number of paramaters. I have a project for ~300 UFB with 15 parameters per one block. There is maximum 2 hours to configure all this blocks.
With best wishes...
