C3.1 Input Type Selection
Input types may be selected either using hardware switches (for all loops collectively) or
using software (for individual loops).
Input type selection using software is available only when switches SW1-4 = OFF and
SW5 = 0. Input type selection by software uses the I/O data register for the Input Type
Selection (IN) parameter. For details on input type selection using switches, see Section
A4.1, "Selecting Input Type and Power Frequency."

*1: You can also select the input types using hardware switches as described in Section A4.1, "Selecting Input Types and
Power Frequency." If a selection is made using hardware switch, the setting cannot be changed by software.
The I/O parameters, including the input type selection (IN) parameter, must be enabled
before their settings can take effect. For details, see Section B2.3, "How to Enable
Settings."
