Chapter 2 - Creating Your First Project
Often the best way to learn about new software is to just jump right in. This chapter will step you through the process of
installing the BlueLeaf configuration software and then using the software to create a sample project that can be downloaded
to your OIT. We won’t go into much detail as to how each feature works. The purpose of this chapter is only to provide you
with an overview of the process of creating a functional OIT that can communicate to a PLC. For our sample project, we
will configure the OIT using the Modbus RTU protocol but you may feel free to select whichever protocol driver you intend
to use.
By the end of this chapter, you should be able to:
Install and start the BlueLeaf configuration software.
• Create a sample project with two screens and several graphics objects.
• Save a project, compile a project, and download the project to the OIT.
• Verify that the OIT is functioning properly.
Before You Begin
Before you install BlueLeaf, make sure your computer meets the following minimum system requirements:
• Pentium-based 90MHz or higher processor
• 16 MB of RAM (more memory improves performance)
• 10 MB available hard disk space
• VGA or higher-resolution monitor set for 256 color 800x600 pixel mode
• Microsoft Mouse or compatible pointing device
• One available RS-232 port
• Microsoft Windows 95, 98, NT or higher
Connecting OIT to Computer
Before you start your first project, the OIT should be connected to the computer so that the project can be downloaded after
creating it. You should also connect the PLC that you are using to the OIT so that you can test the operation of the OIT after
you have finished creating this sample project.

To connect your OIT to the computer
1. Connect a +24VDC power supply to the OIT.
2. Connect the programming cable (Maple P/N 7431-0102) to the computer and OIT.
• Connect the end marked
HMI
to the OIT port labeled
RS-232/RS422
.
• Connect the end marked
PC
to the COM port of the computer.
3. Apply power to the OIT.
