Chapter 4. Functions
If the advanced loop type setting is enabled for
[Loop type]
, any loop type can be selected regardless of the model
number. However, input assignment is required for the PV and RSP. Virtual AIs (analog inputs) can also be used for
input assignment. The loop type can be set by the SLP-C7 Smart Loader Package.
z
Loop types
Normally, the implemented analog inputs are assigned to the PV and RSP of each
loop without overlapping. The number of analog inputs is different for each model,
which means that the selectable loop types differ depending on the model.
However, if the advanced loop type setting is enabled, any loop type can be selected
regardless of the model, because the standard numerical codes can be assigned to
the PV and RSP instead of to analog inputs, and overlapping of assigned numerical
codes is also allowed.

Input assignment
Normally, when a loop type is selected, analog inputs of a certain block are
automatically assigned to the PV and RSP.
In the case of advanced loop type setting, the standard numerical codes are assigned
to the PV and RSP according to the setting.
