Re: [foxboro] ECB8 parameters online edits

I have added rungs (and deleted them) without any isue using the ladder editor 
and it doesn't affect other conected parameters (no reset "true-false-true" for 
example). But when editing parameters into the block like IFLs (not the logic) 
i'm not sure about a posible momentary transition. Maybe you can FORCE ON/OFF 
the output values while editing and CANCEL FORCE after to freeze outputs from 
the PLBVIEW app.
