Input data used for analysis can be viewed through the Control Loop asset Monitor
Ex CLAM Faceplate tab - Trend as shown in
PV, SP, and CO can be adjusted as necessary.

Description
Flag documenting whether a loop is the inner or
outer loop in a cascade (no performance
index). If a loop is master the flag is set to 1 and
0 otherwise.
steps (no performance index). This can be
useful for tuning, model identification etc. If the
data contains one or more setpoint steps the
flag is set to 1 and 0 otherwise.
Flag indicating if the data set is suitable for
model identification (no performance index). If
the data is suitable the user does not have to
perform own tuning experiments. If the data is
suitable for model identification the flag is set to
1 and 0 otherwise.
Index storing static input/output gain for tuning
purposes (no performance index), i.e. static
nonlinearity analysis.
Stores the prediction horizon used by Harris
Index (no performance index). This parameter
is also used to store error signals from the
calculations.
Reports which Loop Category the loop was
assigned (no performance index).
