B3.2 Setting I/O Parameters
I/O parameters are classified into two categories: required I/O parameters that must be
checked and set, and optional I/O parameters that can be set as required. All I/O
parameters apply to individual loops.
The required parameters are described in Sections B3.2.1, “Input Type Selection,” and
B3.2.2, "Control Type Selection."
Optional I/O parameters are used for changing the input range, for selecting burnout
detection, as well as for setting the upper and lower limits of the PV range when using
Two-input Changeover control.
For details on functions selectable with optional I/O parameters, see Chapter C3,
“PV-related Functions”.
I/O parameters must be enabled before any written content can take effect. For details on
how to enable parameter settings, see Section B2.3, “How to Enable Settings.”
Changing an I/O parameter initializes operation parameters and other related I/O
parameters. Therefore, always set I/O parameters before setting operation parameters.
B3.2.1 Input Type Selection
These parameters specify the input type of individual loops. Select a preset value that
matches the temperature range and voltage range of the sensor to be used.

Frequency." If a selection is made using a hardware switch, the setting cannot be changed by software.
