This video gives basic information on Using the Normally Open Contact in the Do-more Designer software. It presents information that is commonly missed by users. This WILL NOT be a complete tutorial for the instruction but rather a supplement to the help file and customer experience.
While assigning a Bit to the contact this display will inform you if the bit assigned has been previously used. This will be indicated by an X. This contact mimics the behavior of a momentary normally open relay. When the assigned bit is on, the contacts close, allowing power flow. This contact can be assigned to the ladder logic by using the F2 hotkey.
