The input logic convention is programmable for each of the five inputs. Most inputs
default to normally open (active high), but you can select normally closed (active low) in
order to invert the sense of the logic.

NOTE: An input terminal configured for option code 18 ([RS] Reset command) cannot
be configured for normally closed operation.

Intelligent Input Terminal Overview

Each of the five intelligent terminals may be assigned any of the options in the following
table. When you program one of the option codes for terminal assignments C01 to C05,
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 “Forward Run” command is [FWD]. The physical label on the
terminal block connector is simply 1, 2, 3, 4, or 5. However, schematic examples in this
manual also use the terminal symbol (such as [FWD]) to show the assigned option. The
option codes for C11 to C15 determines the active state of the logical input (active high
or active low).
