Overview
Each of the eight intelligent terminals may be assigned any of the options in the following
table. When you program one of the option codes for terminal assignments C001 to C008, the
respective terminal assumes the function role of that option code. The terminal functions have a
symbol or abbreviation, which we use to label a terminal using that function. For example the
“Reverse Run” command is [RV]. The physical label on the terminal block connector is simply
1, 2, 3, 4, 5, 6, 7, or 8. However, schematic examples in this manual also use the terminal
function symbol (such as [RV]) to show the assigned option. The option codes for C011 to
C019 determine the active state of the logical input (active high or active low).
