Module Data, Status, and Channel Configuration for the Input Module 3-11
Valid Input Data Word Formats/Ranges
The following table shows the valid formats and min./max. data ranges
provided by the module.
1769-IF4I Real Time Sampling
This parameter instructs the module how often to place the most recently
scanned data for each enabled input channel into the Input Data file. This
feature is applied on a module-wide basis.
During module configuration, you specify a Real Time Sampling (RTS) period
by entering a value into Word 0 of the Configuration Data file. This value
entered in Word 0 can be in the range of 0 to 5000 and indicates the sampling
rate the module will use in 1 ms increments.
If you enter a 0 for the Real Time Sample Rate, the module will place each
input channel’s most recently scanned data into the Input Data file at as fast a
rate as possible, controlled by the filter setting selected for each enabled
channel.
