10.1 Scan Time
10.1.3 Factors that increase the scan time
(9) Time taken to collect module errors
When using the module error collection, the scan time increases by the time found by the following calculation
formula.
Calculation formula
Collection time = N1 + N2 (Number of module errors collected in one scan)
The following table shows N1 and N2 values.
