Estimated time, in seconds, it takes for the process to respond to the slowest responding input. This field also corresponds to the horizon over which DeltaV Neural estimates input delays.
The Time to Steady State (TSS) is calculated as:
TSS = 50 × Data Sampling Rate × Sample Multiplier.
The Data Sampling Rate is the Historian Sampling rate entered in the NN function block Properties dialog. If you are using data from a file, the sampling rate in the file is read as the Data Sampling Rate for the TSS calculation.
To modify the TSS, edit the Sample Multiplier as shown in the formula above. For example, if Historian Sampling Rate is one second and the process TSS is estimated to be 100 seconds, set the Sample Multiplier to two (2). If you are using data from a file in which the sampling rate is two seconds, the minimum possible TSS is 100 seconds (Sample Multiplier = 1). Other possible TSS values are 200 seconds, 300 seconds, and so on for Sample Multipliers of 2, 3, and so on.
