2. Next, right-click on IDAS and select New I/O Server
- Complete the I/O Server Location field with the node name that the I/O Server is located on.
- Choose the appropriate I/O Server type from the list.
- Choose the appropriate Protocol Type (DDE for non-AVEVA Servers).

Section 2 – Analog Tag Example
6. Now that we have an I/O Server and Topic configured we can create tags. The first example will be an analog tag. Right-click on the Topic in the hierarchy. Select “New Analog Tag” Enter the appropriate tagname and click on Next.

9. Now, configure the desired Storage Method and storage Deadband. Typically, we will leave the Active Image configuration default. Click on Finish.

10. This tag should now be shown in the right-hand pane. The last step is to “Commit Pending Changes” which must be performed during most configuration changes on running InSQL servers. Right-click anywhere in the hierarchy in the left-hand pane, and select “Commit Pending Changes” Click on the Commit button.
