How Communication Takes Place and I/O Image Table Mapping with the DeviceNet Adapter 5-3
System Throughput System throughput, from analog input to backplane, is a function of:
• the data format selected
• the type and mode of sensors selected
• whether filtering is selected
The A/D converter which converts channel 0 through 7 analog data to a
digital word provides a programmable single low pass filter. You can set the
frequency of this filter during module configuration. The selection
influences the A/D output data rate, thus affecting system throughput.
