the Brightness group box, select the 100%, 75%, 60%, or 30% option button.

the Installation Manual that came with the OIT. For the OIT3160, OIT3165, OIT3175,

OIT Operation
OIT Displays a Blank Screen when power is applied
Possible Causes:
•
If the OIT displays a blank screen and you hear a steady beeping, then the OIT does not
contain a complete project and is waiting in download/upload mode for OITware-200 to
download a project. Simply connect the OIT to your computer and use OITware-200 to
download a new project to the OIT.
•
If the OIT displays a blank screen after displaying “Initializing” and “Attaching to PLC”,
then the OIT is communicating to the PLC, waiting for a command from the PLC or from
the keyboard to display a message. Configure one of your messages as a startup message
if you want a message to automatically display on the OIT after power is applied.
Possible Solutions:
•
Download the OITware-200 project, OIT operational software, and PLC protocol
software to the OIT again. Follow the steps in the Downloading an OITware-200 Project
section in CHAPTER 1: Getting Started.
•
Configure one of the messages as a startup message.
OIT is Not Displaying Expected Information on the Display
Possible Causes:
•
The OIT does not contain the entire OITware-200 project, OIT operational software, or
PLC protocol software.
•
The OITware-200 project was not configured to do what you expect.
Possible Solutions:
•
Download the OITware-200 project, OIT operational software, and PLC protocol
software to the OIT again. Follow the steps in the Downloading an OITware-200 Project
section in CHAPTER 1: Getting Started. Observe the messages on both the PC and OIT.
Note any messages that indicate a problem.
•
Review the OITware-200 project.
