Right-click a Register or Handshake control or constant and select Configure Register Type or Configure Handshake Type from the shortcut menu to display this dialog box.

Use this dialog box to configure the Register or Handshake control or constant. You can specify the data type of the register item or handshake item.

This dialog box includes the following components:

Option Description
Data Type Specifies the data type of the data in the register item. Click the arrow to see the list of supported types. If you select FXP, configure the data type in the Fixed-Point Configuration section.
  • Fixed-Point Configuration—Sets the configuration settings for fixed-point data. Set Data Type to FXP to enable the fixed-point settings. LabVIEW automatically determines the Range based on the Encoding settings you specify.
    Note Register items do not support overflow for the fixed-point data type.
  • Encoding—Sets the binary encoding settings for a fixed-point value.
  • Signed—Sets the fixed-point data to represent a signed number.
  • Unsigned—Sets the fixed-point data to represent an unsigned number.
  • Word length—Sets the number of bits that LabVIEW uses to represent the possible fixed-point values.
  • Integer word length—Sets the number of integer bits, or the number of bits to shift the binary point to reach the most significant bit, for all the possible fixed-point values. Integer word length can be positive or negative.
  • Range—Indicates the range for a fixed-point value.
    Note LabVIEW displays these values in double-precision floating-point representation, so the precision of Maximum, Minimum, and Delta might not be exact in terms of fixed-point representation. However, the deviation is very small.
  • Minimum—Indicates the minimum value for the fixed-point data range.
  • Maximum—Indicates the maximum value for the fixed-point data range.
  • Delta—Indicates the maximum distance between any two sequential numbers in the fixed-point data range.
  • Custom Control—Opens a dialog box in which you can navigate to the custom control you want to use. This button appears only when you select Custom Control in the Data Type pull-down menu.
