Scheduler Interface

Maker utility can only configure SCH-10 modules that have device or
functional block shapes in this top-level subsystem.

7. Select the SCH-10 device to be configured in the SCH-10 Devices list.

8. Click the Download Design button to configure the selected device. Any

previous schedule design for the device will be overwritten. The download
may take one to five minutes depending on schedule size and network load.
If you are OnNet, you can speed up downloading by turning off monitoring
in the LonMaker tool. A status message at the bottom of the Load/Save tab
will display the download status. When the status message is cleared, the
download is complete.

Once you have finished loading, saving, and downloading designs into a
network, you should close the network database by clicking the Close button.
You may then open another database if you wish.

Click the Exit button in this tab to exit the LonPoint Schedule Maker
application.

Setting the SCH-10 Time

Prior to using the SCH-10 module for the first time, you must ensure that it has
the correct date and time. To set the time, follow these steps:

1. Open a drawing containing the SCH-10 device using the LonMaker tool.

2. Right-click the Real-Time Clock functional block and select Browse from the

shortcut menu.

3. Right-click anywhere in the row containing the SetTime network variable

and select Details from the shortcut menu.

4. For each field, click the plus sign next to the field, click twice on the value

(i.e. slower than a double-click), and enter the correct value.

5. Click OK to update the time.

Changing the Mode and Mode_Out Types

By default, the Mode and Mode_Out network variables of the State Machine
functional block are the SNVT_hvac_mode type. You can change these types to
generate different types of mode inputs or mode outputs. However, the types
must be set to SNVT_hvac_mode when downloading a design as described in the
previous section.

To change the type of the Mode or Mode_Out network variables, follow these
steps:

1. Download the design to the SCH-10 module as described in Downloading a

Supervisory Application Design.

2. Open the LonMaker subsystem containing the State Machine functional

block.
