other functional blocks in your system. To simplify using these inputs and
outputs, you will assign names to each input or output that you plan to use.
These names are only used in your schedule design, and are not downloaded to
the SCH-10 module. In the following examples, input names start with an i
prefix and output names start with an o prefix (except when using a digital
output schedule as described in the next paragraph), so example names are
iSystemEnable and oOccupied.

When defining a digital output schedule, the digital output names must be the
same as the event names used to control the outputs. This “wires” the event
names to the digital outputs. For example, if the schedule defines evtOccupied
On and Off events, and evtWarmup On and Off events, there must be digital
outputs named evtOccupied and evtWarmup.

In addition to the digital inputs, the State Machine functional block has a mode
input and output, an event input, and an internal power loss input. These
additional inputs and outputs cannot be renamed.

To define input and output names, follow these steps:

1. Drag an Digital Inputs shape from the LonPoint Scheduler stencil to your

LonMaker drawing.

2. Double-click the Digital Inputs shape. A drawing of the shape opens in a

new window.

3. Assign a name to each of the digital input network variables that you plan to

connect to other functional blocks. Fill in an optional description for each.
The optional description is useful for as-built reports.

4. Close the Digital Inputs shape drawing window.

5. Repeat steps 1 through 4 for your analog input network variables using the

Analog Inputs shape.

6. Repeat steps 1 through 4 for your digital output network variables using the

Digital Outputs shape. The names for the digital outputs must be the same
as your event names if your digital outputs will be controlled directly by the
