Analog Input Functions and Operating Procedures Section 2-6
Response Time at 250-µs
Conversion Time/8,000
Resolution
Unit: ms
Symbols M: Number of input words used in DM Area
N: Average number of buffers set for the input number for which to find the
response time
Calculation Example The following example calculations are for a resolution of 8,000 with an appli-
cation using inputs 1 and 8, 64 averaging buffers set for input 1, and no aver-
aging set for input 8.
• Response time for input 1: t = {(64
− 2) x 2 + 10.5} x 1/4 = 34 (ms)
• Response time for input 1: t = 1 x (2 + 2) x 1/4 = 1 (ms)
2-6-4 Peak Value Hold Function
The peak value hold function holds the maximum digital conversion value for
every input (including mean value processing). This function can be used with
analog input. The following diagram shows how digital conversion values are
affected when the peak value hold function is used.
The peak value hold function can be set individually for each input number by
turning on the respective bits (00 to 07 for CS1W-AD081-V1, 00 to 03 for
CS1W-AD041-V1) in CIO word n.
