Downloading/Uploading a Project

Before you can access the controller, you must establish PC-PLC communications.

You can establish PC-PLC communications via Ethernet or USB cable.

Ethernet

Connect your PC to the controller using an Ethernet cable.
Access the controller's Ethernet settings by opening UniApps.
UniApps is a collection of applications and tools that are embedded in the operating system of the controller. Via UniApps, you can perform a number of operations, such as:
- View and edit system data
- Run updates to upgrade different aspects of the controller
- View and edit communication settings
- Implement Working Mode actions such as resetting the controller.
You can enter Information Mode at any time without regard to what is currently displayed on the LCD screen.

Entering UniApps:
- Touch and maintain contact for several seconds with the upper right corner of the HMI Panel touchscreen until UniApps appears.
Check under Network> Ethernet to see the controller's IP address, subnet mask, and default gateway.
Note that you can edit these values by touching a field to open the keypad.
In UniLogic, on the Solution Explorer, click PLC Communications>Panel. The settings here must match the controller's settings.
Click the PLC tab on the program ribbon, and then click Communication.
Select Ethernet, and enter the controllers address; you may need to click the refresh icon in order to establish communications.

Click OK.

USB

Directly connect your PC to the controller using a mini B USB cable.
Click the PLC tab on the program ribbon, and then click Communication.
Select USB; the network Discovery utility will begin to search for UniStream devices.
Click the desired device to establish communications.

After establishing communications:

Click the PLC tab on the program ribbon, click Download or Upload, and then select the desired option.

Download Options

Full Download

Compares the project in the PC to the project in the controller; downloads only the differences, including Media folders

Logic only

Downloads the project without Media folders

Media only

Downloads only the contents of the Media folders

Full download with Upload

Select this option if you want to enable project upload.

Logic only with Upload

Select this option if you want to enable project upload.

Download all

This downloads the complete project, overwriting the entire project in the PLC. Note that it does not include the ability to upload the project.

Export Project as a file

You can export a complete project to a local or external drive, or to an SD card, and then install an exported Project File into any number of PLCs as a new project, or use it to update an existing base project. You can import a project file via UniApps, or vis Ladder function.

To install the project from an external flash drive or SD card, install it in the appropriate UniStream port, and then, in UniApps, select System>User App Upgrade>Import Application.

To install via Ladder function, refer to LF: Update Application.

Note that the model and OS of the UniStream units must be identical.

The network Discovery utility will begin to search for UniStream devices; click the method USB or Ethernet, and then click the desired device to begin download.

Download via USB

Download via Ethernet

Ethernet, or IP Favorites, is a global file that is available in all of your UniLogic projects.

Note

To access the controller's Ethernet settings,open UniApps and check under Network> Ethernet.
To download Logic-only via the last used PC-PLC Communication method, you can use the keystroke Ctrl + D.
HMI Screens
-After Project Download and Power-up: The main screen loads
-After Project Updates: after downloading an update, the screen that was being displayed when the project was downloaded will be shown immediately after download, followed by the main screen.

UniStream PLCs (UniStream without built-in HMI panel)

The default IP address of a UniStream PLC is 192.168.10.1.
Note that Basic (B3) models do not offer a USB device port, and may be programmed via Ethernet.

PLC Restart after Download

When you edit an existing program and download it to the same controller, the controller may require restart. The PLC will require restart if:

Note that after a firmware update, the controller may need to be turned off and on (powering-off and powering-on).

You can view the Signature log containing the history of your project by selecting the Tools> Signature icon on the UniLogic ribbon.
