Each object in the I/O Map can take values from 0–100%. On/O digital objects such as switches take
a value of 0% when O and 100% when On. Analog objects can take a value anywhere between 0%
and 100%. If an analog object is mapped into an object expecting a digital value, it is interpreted as
0% = O and any non-zero value = On. An analog value when mapped into an output object could
represent duty cycle or, if programmed for voltage compensation, a percentage of max voltage.
PROGRAMMING THE 1229
Use the I/O Map functions (objects) to construct the 1229 application program. When setting up
a new application, use a whiteboard or take “pencil-to-paper” and track the desired logical and
decisional sequences from each input to its output (i.e., signal-in to action-out) to achieve the desired
result. An application will have multiple of these I/O Maps as it uses the external inputs to the 23-pin
connector or CANopen to form the control commands to operate. Refer to the wiring diagrams in
Chapter 2 and the parameters in Chapter 4 as needed to establish the application’s program control.
Use the Logical Gates truth tables to apply logical structure to the program sequences. Each of the
ten logical objects (41-Logic Gate 1 through Logic Gate 10) oer an AND, OR, and XOR option.
Each output can be inverted to form NAND, NOR, and XNOR gates.

gate are TRUE/HIGH/ON (1). ink of the AND function as nding the minimum of its inputs. e
