I see that in this conversation there is discussion on being able to manually enter P,I, and D settings from a touch screen. I also need to be able to do this but I can not figure it out. I can find the following in the PID_Compact FB... P = r_Crtl_Gain I = r_Ctrl_Ti D = r_Ctrl_Td But I can not figure out how to read or write to these points. I am guessing it would look something like when accessing a Data Block (ex.%DB14.DBW0) Any help would be great. An example would also be nice!? Thanks Steve
