B3.1.3 Monitoring Mode
The monitoring mode parameter configures how channels are combined. The module
supports Single-input mode and Two-input Changeover mode. In Two-input Changeover
mode, two channels are combined and used as one.

Single-input Mode
This is the standard mode of use.
In Single-input mode, each input operates independently,
and is configured separately. Descriptions in Section
B3.2, “Setting Input Parameters” and Section B3.4,
“Operation” assumes the use of Single-input mode.

Two-input Changeover Mode
Two-input changeover mode uses two channels of
monitoring functions to monitor a single process value, by
switching between two inputs.
In this mode, setup and operation acts on a pair of
channels (channels 1 and 2, or channels 3 and 4). Only
parameters of even (2, 4) channels are used for
controlling.
Descriptions in Section B3.2, “Setting Input Parameters”
and Section B3.4, “Operation” assumes the use of
Single-input mode. For details on setup and operation
unique to Two-input Changeover mode, see Section
C1.2, “Two-input Changeover Mode.”
