Configuration Tab 1756-IF6I and -IF6CIS, integer

Use this tab to configure the 1756-IF6I and 1756-IF6CIS integer, analog input modules.
Use the
Configuration
 tab to:
  • Select the channel to configure
  • Select an input range
  • Select a notch filter frequency
  • Enter a real time sample period
    TIP:
    The module’s configuration information is stored in the controller and the controller configures the

    module.
    module
    A device, typically an I/O device, that communicates with the controller. The controller, a particular 1756-IB16I or a PanelView are all considered modules.
Parameters
Channel
Select one of the channel buttons to display its information on this tab.
Input Range
Select the operating range of a specific channel.
  • -10 to 10V
  • 0 to 5V
  • 0 to 10V
  • 0 to 20mA
The 1756-IF6CIS module has only 1 operating range (0-20 mA).
Notch Filter
Select a frequency. This filter attenuates the selected frequency and its harmonics in the input signal. You can choose the filter frequency to filter out line noise.
RTS (Real Time Sample period)
Enter the time (in milliseconds) to indicate how often the module’s inputs are to be sampled.
There is only one RTS for the entire module (you can’t have a different one for each channel).
The RTS period controls how often the module prepares new readings. The Requested Packet Interval (RPI on the Connection tab) controls how often the module sends its current readings to the controller. Generally these two values should be similar so that each reading gets sent to the controller one time.
OK
Select this button to accept your edits on any tab and close the dialog.
Cancel
Select this button to cancel your edits on any tab and close the dialog.
Apply
Select this button to apply your edits on any tab and continue editing.
If:
  • You are online in Program, Remote Program or Remote Run mode and,
  • This controller is the owner controller and,
  • You have changed the module’s configuration in the software,
when you select the Apply or the OK button, the information is automatically sent to the controller. The controller tries to send the information to the module (if the module’s connection is not inhibited). If you don’t select Apply, your changes are not sent to the controller.
