Assign Unit Attribute Values

After an attribute has been created, you must define specific values for each attribute of each unit that belongs to the process class. You can assign only numeric values. You may need to define an external translation table so that value assignments can easily be related for the appropriate attribute. In the example plant referenced earlier, stainless steel reactors have been assigned a value of 1 and glass lined reactors have been assigned a value of 2. Also, a separation type of 1 represents the presence of a liquid/oil separator, while a value of 2 represents the presence of a liquid and solid separator.

To assign a unit attribute value

1. On the Processes tab, select the required unit from the Units list.

   

2. Select an Attribute from the Attribute list.

3. In the Value box, type the value of the attribute for the selected unit.

4. Click Change.

   The value appears in the Attribute and Value list.
