Edit button

Click this button to open the selected graphic display for editing in the Graphic Displays editor.

Edit button

Click this button to open the selected information message file for editing.

Acknowledge hold time

Select the minimum length of time to hold the Ack connection value at 1 after the operator presses the information acknowledge button. If the operator is still pressing the button when the hold time expires, the connection is not reset to 0 until the operator releases the button.

Maximum update rate

Select the maximum rate at which data servers will supply data to the Value tag specified in the Connections section. This includes any tags used in Value expressions. The default update rate is 1 second.

At run time, all Value tags are updated immediately upon startup, no matter what the update rate is.

Connection

Assign a tag or expression to these controls:

  • Value - a read connection. You can assign a tag or an expression to this connection. The graphic display opens when the Value connection at the data source changes from zero to any non-zero value. If the value matches a message's trigger value, the message is shown. If you assign an expression, the application calculates the value of the expression and displays the message with the trigger value that matches the expression value.
  • Ack - a write connection. Assign a digital tag to this connection. When the operator presses the information acknowledge button, the Ack connection is set to 1 at the data source. When the acknowledge hold time expires, the connection is reset to 0. If the operator is still pressing the button when the hold time expires, the connection is not reset until the operator releases the button.
