Set up handshaking for the numeric input cursor point (Timing tab)

When the operator presses the Enter button, the numeric pop-up keypad or scratchpad writes a value to the data source. Use Enter key handshaking to hold the value at the data source for a specific period of time to ensure it is read before the operator sends a new value to the Value connection.

Tip:

For these settings to take effect, you must assign controls to Enter and Enter handshake in the Connections tab.

To set up handshaking for the numeric input cursor point

  1. In the Graphics Display editor, double-click the numeric input cursor point to open its Properties dialog box.
  2. In the Timing tab, specify the handshaking settings to use with the numeric input cursor point.

Options

  • Enter key control delay

    Select the length of time to delay between the time the operator presses the pop-up's Enter button and the time the application sets the Enter connection to 1. Assign the Enter connection in the Connections tab.

  • Enter key hold time

    Select the time the Enter connection will be set to 1. This time setting applies only if the Enter connection is assigned and the Enter Handshake connection is not assigned (in the Connections tab).

  • Enter key handshake time

    Select the maximum time the Enter connection will be set to 1. This time setting applies only if the Enter and Enter Handshake controls are both assigned (in the Connections tab).

  • Handshake reset type

    Select how the Enter Handshake connection resets the Enter connection to 0:

    • Non-zero value resets the Enter connection when the Enter Handshake connection is a non-zero value.
    • Zero to non-zero transition resets the Enter connection when the Enter Handshake connection changes from 0 to a non-zero value.
