I have a question about DD.When I use advanced function blcok's DD library,I found that some input parameters were defined to be output parameters .For example,"Disable_1"and"Op_Select" is one of the input parameters of the INPUT SELECTER function block,but in the file "adv_parm.ddl",these two parameters were defined to be the output class. I also found that most of the advanced function block have the same problems as I described above.Could you tell me why they were defined to be a output parameter?
