4-8 Preliminary Operating Considerations
Update Time Calculation Example
The following example shows how to calculate the module update
time for the given configuration:
• channel 0 configured for 250 Hz filter frequency, enabled
• channel 1 configured for 250 Hz filter frequency, enabled
• channel 2 configured for 50 Hz filter frequency, enabled
• channel 3 disabled
Using the values from the table above, add the the sum of all enabled
channel sample times, plus one CJC update time.
• channel 0 sampling time = 12 ms
• channel 1 sampling time = 12 ms
• channel 2 sampling time = 60 ms
• CJC update time = 14 ms
Module update time = 12 + 12 + 60 + 14 = 98 ms
