DRT1 Series
Supplied by local power supply terminal.
30 mA max.
Poll, Bitstrobe
Just temperature data for 4 inputs
Set using the DIP switch.
Set using the DIP switch.
Not supported.
Supported.
Not supported.
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.
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.
Calculates the average of the past eight analog input val-
ues, and produces a stable input value even when the input
value is unsteady.
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).
Supplied by communications power supply.
70 mA max.
Poll, Bitstrobe, COS/cyclic
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.
Set using the rotary switches or the Config-
urator.
Automatically detected: Uses the baud rate
set for the Master Unit.
Supported. (Set using Configurator.)
Supported. (Set using Configurator.)
