Data Weaver

The companion application that connects this computer to a controller on behalf of Logic Weaver.

Install on Windows

Data Weaver installs for the current user only — no administrator rights needed — and updates itself.

Checking the current version…

Signed by WCW Automation

Data Weaver is signed by WCW AUTOMATION LTD. Because it's new, Windows may still ask you to confirm for a while:

Your browser may say the file isn't commonly downloaded — choose Keep.
Windows may show a blue “Windows protected your PC” box — click More info. Check that Publisher reads CA, British Columbia, Courtenay, WCW AUTOMATION LTD., WCW AUTOMATION LTD., then click Run anyway. Can't see the buttons? The box is cut off — drag its edge to make it bigger, or maximize it.

If the publisher says Unknown publisher or any other name, click Don't run — that file didn't come from us. These notices fade as more people install Data Weaver.

Download Data Weaver only from this page.

After installing

Data Weaver opens by itself when the installer finishes.
In Logic Weaver (Chrome, Edge or Firefox), choose Connect to PLC… from the avatar menu — it finds Data Weaver on its own.
Click Pair this browser, then approve the request in the Data Weaver window. Once per browser.
Add your controller in Data Weaver's Controllers screen, or type its address in Logic Weaver.

Live Testing is a Max-plan capability of Logic Weaver. Data Weaver talks only to Logic Weaver on the same computer; nothing is exposed to your network.
