Introduction

 In this example DASSim will be used. This DAServer simulates values. A tagname/register we can read is called Integer1. 

1. I will test "Integer1" with wwclient. You can see in this example we can read the value and quality is good.
   
   Since Integer1 might not mean a lot to most people we want to add an alias that has meaning to this tag. I will call it “TankLevel1”
    
2. Open up your OI/DAServer configuration. Go to the Device Items tab(next to Device Group). 
   
3. Right click the blank space and select "Add".
   
4. Now you want to create the alias. In the Left side under "Name" create the name you would like the tag in the PLC to be referenced by. In the right side under "Item Reference" You will put the tag/register as it exists in the PLC.
5. I can now advise both tags with wwclient using either name. TankLevel1 is easier to identify then Integer1.
