But I have to repeat it 8 times because I want to do the same thing on all my LOGO's Output. So that's why I created an UDF file. With all the logic blocks I need. I did exactly the same thing as I did on my first logic diagram (copy/paste). I just created an input on the UDF for the loop that Q1 output does on the LOG. This UDF has 4 input: 1 for M8, 1 for the loop of Q1, 2 for my input I1. (There are 2 cases: 1 for a Normally Open (NO) output (Q) and 1 for a Normally Closed (NF = NC in english) output (Q)) My UDF works very well for the NO case, but it doesn't work for the NC case. It is really strange because it works if it's not in a UDF. Has someone an idea? Thank you for your help Attachment Bloc éclaté pour udf.PNG (346 Downloads)

Blocks with purely logical functions (AND, NAND, OR, NOR etc.), whose inputs are connected to inputs of the UDF, only work if these UDF inputs are then connected with other blocks.
