I am trying to get the V120_Keypad_Entry_Variable_Control.vlp example program to work in order to adapt the concept to a current project. The example program allows one to switch to a 'Variable Entry' screen in order to update 6 variables and then save them and then return to a main screen with the ESC key. Upon entering the 'Variable Entry' screen, any variable may be selected for change by scrolling through the variables using the right arrow key. The selected variable is indicated by a scrolling graphic of an arrow. When the desired variable is reached, pressing the ENTER key should make the indicated variable active, thereby allowing it to be changed. Another press of the ENTER key should save this newly changed variable, and then scrolling to another variable can continue. When all desired variable are changed, hitting the ESC key will return us to a main screen. At least that is my interpretation of what the program should do. What actually happens is that the scrolling arrow icon and the scolling active variable (indicated by the blinking cursor) are out of sync, so that pressing the ENTER key on a variable highlighted by the arrow icon actually activates some other variable. Now the active variable may be scrolled thru the 6 positions while the arrow icon does not move. Is this operation correct? What am I missing? or is something wrong with the program? Original unedited sample program is attached. PLC: V120-22-R1 Visilogic 9.4.0 Build 0 V120_Keypad_Entry_Variable_Control.vlp
