This section describes how DRT2-slave data can be allocated for remote I/O
communications with the Master Unit.
3-2-1 Overview of Remote I/O Allocations for Smart Slaves
Unlike the DRT1-series Slaves, the DRT2-series Smart Slaves store data
internally. When necessary, the user can specify which data is allocated for
remote I/O communications with the Master Unit. (Allocation is not required,
however, for the default I/O data.)
• Data can be specified in either of the two ways described below.
Smart Slave I/O

using the Master’s connection set-
ting.
