B2.2.10 I/O Parameters
The I/O parameters are classified into two categories: required and optional. The required
setup parameters must always be checked and set, and the optional setup parameters
may be set as required. All I/O parameters apply to individual loops.
The required setup parameters are input type selection and control type selection
parameters. They are the most basic loop setup elements.
The optional setup parameters include PV-related parameters for changing the input range
and selecting a burnout operation, as well as parameters that are used only in two-input
changeover mode.
 I/O Type Settings
These parameters are used to select input types (ranges) and output control types for
individual loops. These parameters are the most basic loop setup elements.

*1 To select input type by software, you must set the input type selector switches to “set by software”, that is, “SW5=0 and
SW1-4=OFF” (also see Section A4.1, "Selecting Input Types and Power Frequency").
 Input Range Settings
Use these parameters to set up the input of individual loops, as required, such as
changing the input range or selecting an appropriate burnout operation.
