The Project Properties window is displayed.

Communication Error Message
If a user is attempting to write to a project in the Designer or from a Client, and the Comm Mode is not enabled for Read/Write, they will get an error message. There are a couple places to check:
- From menubar Main Toolbar go to Project, and make sure to see if the Comm Mode is set to Read/Write.
- If Comm Read/Write is checked, you may have a Client Event Script enabled that could be preventing you from writing to a project or a Tag, as shown in the example below. From the menubar, go to Project > Client Event Scripts. You may need to edit your Client Event Script.
