Notch Filter
Select a notch filter for this channel. The following are valid values.
  • 242 Hz
  • 123 Hz
  • 62 Hz
  • 19.6 Hz
  • 16.7 Hz
  • 10 Hz
  • 4.17 Hz
The default value is 242 Hz.
Enable HART
Select this check box to enable HART communication on this channel. If the check box is cleared, no HART data is available via the MSG instruction, the HART data is not updated in the Input Tag, and you cannot enable the HART current fault ratio limit or the HART commands.
The HARTFault bit is set for this channel in the Controller Tag.
Enable HART Current Ratio Limit
Select the check box to enable the HART current fault ratio limit on the channel. Clear the check box to disable this feature on the channel.
This field appears dimmed when the Enable HART check box is cleared.
HART Current Ratio Limit
Select the current ratio limit for the channel. Valid values are 5...31 percent of full scale.
The HART Current Ratio Limit appears dimmed when the Enable HART Current Ratio Limit check box is cleared.
OK
Click this button to accept your edits and close the dialog box.
Cancel
Click this button to close the dialog box without accepting your edits.
Apply
Click this button to accept/apply your edits. If the following conditions exists when you click Apply or OK,
  • you are online in Program, Remote Program or Remote Run mode and,
  • this controller is the owner controller and,
    controller
    A device that controls machines or processes elements (for example, a programmable controller or relay panel).
  • you have changed the module’s configuration in the software,
the information is automatically sent to the controller. The controller tries to send the information to the module (if the connection to the module is not inhibited). If you don’t click Apply or OK, your changes are not sent to the controller.
