# Development Workflow

Create the project file (*.blu) following the steps below.

1. Setting up Display Units and External Devices

2. Creating Variables
3. Creating Screens
4. Simulation
5. Transferring

Note: The [Import Compound Objects] dialog box appears when you launch the screen editing software for the very first time. If required, import compound objects at this time. From subsequent launches, this dialog box will not automatically appear. Instead, use the Compound Object Explorer to import compound objects.

## Setting up Display Units and External Devices

Configure the display unit and external device.

For information about system settings, refer to the following.

Target Settings

Connecting Targets and Devices

## Creating Variables

Create variables for storing various data values. Assign created variables to external device addresses, switches, lamps, alarms, or other objects.

For information about variables, refer to the following.

Steps to Design (Variables, Array, Structure)

## Creating Screens

Draw screens that display on the display unit, and assign scripts to each function.

### Creating the Display Unit Maintenance Screen

To change the display unit settings such as IP address, clock and screen brightness, a Hardware Configuration screen is required.

Create this screen by using Hardware Configuration objects.

## Simulation

Before transferring the project file, you can check project operations on a computer without actually connecting to external devices.
What is Simulation?

## Transferring

By transferring a project file to the display unit, the display unit displays the screen and runs communication with external devices.

For information about the transfer process, refer to the following.

Before Transferring Projects

Note: Transferred project files are stored in the display unit's internal memory (application memory).
