In the Object Explorer window click on the refresh button, this will refresh the SysmacDB to include the newly added dbo.OmronDemoTable.
Step 3 - Configuring Database Security and adding the NJ/NX MAC as a User
In the Object Explorer Window under Security -> Logins, right click and add a New Login.
Under General
