Overview of Analog Slaves Section 7-1
Note The input accuracy depends on the mounting method. For details, refer to the
Performance Specifications in 7-6-1 DRT2-TS04T and DRT2-TS04P Temper-
ature Input Terminals.
7-1-3 List of Data Processing Functions
The following tables list the data processing functions that can be used with
Analog Slaves. Refer to 7-4-3 Functions and Settings for details on functions
and setting methods.
DRT2-AD04/DRT2-AD04H Analog Input Terminals
Unit power supply Supplied by local power supply terminal. Supplied by communications power supply.
Communications power sup-
ply current consumption
30 mA max. 70 mA max.
Connections Poll, Bitstrobe Poll, Bitstrobe, COS/cyclic
Data allocated in Master Just temperature data for 4 inputs Default: Temperature data for 4 inputs
The following data items can be allocated
by making additional Configurator settings:
Peak value, Bottom value, Top value, Valley
value, Rate-of-change value, Comparator
result; Generic Status Flags, etc.
Node address setting Set using the DIP switch. Set using the rotary switches or the Config-
urator.
Baud rate setting Set using the DIP switch. Automatically detected: Uses the baud rate
set for the Master Unit.
Moving average Not supported. Supported. (Set using Configurator.)
Off-wire (disconnection)
detection
Supported.
Scaling, offset compensation,
peak/bottom hold, top/valley
hold, rate of change opera-
tions, comparator
Not supported. Supported. (Set using Configurator.)

Function Details Default
Moving average Calculates the average of the past eight analog input val-
ues, and produces a stable input value even when the input
value is unsteady.
Moving average disabled.
Setting the number of AD
conversion points
(DRT2-AD04 only)
By reducing the number of input conversion points, the con-
version cycle speed can be increased. For details, refer to
7-4-4 Calculating the Conversion Cycle (DRT2-AD04 Only).
