Defining Single Properties ("Property/Definition")

Dionex recommends creating separate properties for values that can be set independently (for example, DrawSpeed and Response).

1. Select Properties or an existing property on the Definition tree structure.

2. Click New.

This action creates a new property with the default settings and opens the dialog box for editing the property. The dialog box provides various options.

• Enter the name for the new property (for example, DrawSpeed). Make sure that the name is unique within the device.

• Select an appropriate number format from the Type field (here: Floating Point).

• Enter the unit for the number value in the Unit field (here, e.g., µl/s).

• Min and Max determine the available value range (here, e.g., 0.01 and 50).

• The Step parameter is not considered for the moment (value = 0) (described below).

• In this example, the Number of Digits is 2. (For an integer, the Number of Digits should be 0.)

• Audit level indicates the filter level from which on this property is displayed in the Audit Trail.

• Using the Command Offset and Command Factor fields, the sent value can be multiplied by a factor and assigned an offset. If the offset is 10 and the factor is 2, the value 100 is changed to (100 x 2) + 10 = 210.

• In the Number of Characters field, enter the maximum number of characters that are allowed if String were selected from the Type list.
