Configuration tab 1756-IF8 and 1756-IF16, integer

Use the
Configuration
tab on the
Module Properties
dialog to configure the 1756-IF8 and 1756-IF16 non-isolated analog input modules operating in integer mode. The configuration information for the module is stored in the controller. The controller configures the module.
Use the
Configuration
tab to:
  • Select the channel to configure
  • Select an input range
  • Select a module filter frequency
  • Specify a real time sample (RTS) period
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 10 V
  • 0 to 5 V
  • 0 to 10 V
  • 0 to 20 mA
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.
Module Filter (-3 dB)
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.
There is only one Module Filter for the entire module (you can’t have a different one for each channel).
