Scaling Performs scaling.
Scaling allows conversion of values between 0 and 6,000 (0
to 30,000 in the DRT2-AD04H) into values using the indus-
try unit required by the user. It reduces the number of oper-
ations requiring ladder programming in the Master CPU
Unit. Scaling also supports an offset function for compen-
sating for mounting errors in sensors and other devices.
0 to 6,000 (DRT2-AD04)
0 to 28,000 (DRT2-AD04H)
Peak/bottom hold Holds the maximum and minimum analog input values. Disabled
Top/valley hold Holds the top and valley values for analog input values. Disabled
Rate of change Calculates the rate of change for analog input values. Disabled
Comparator Compares the analog input value or an analog value after
math processing (value for peak, bottom, top, valley, rate of
change) with the four set values HH, H, L, and LL, and indi-
cates the result with the Analog Status Flags.
Disabled
Off-wire detection Detects disconnections of analog inputs. (Valid only for the
input ranges 4 to 20 mA and 1 to 5 V)
Enabled
User adjustment Adjusts the input when an offset occurs in the input voltage
or current.
Disabled
Cumulative counter Calculates an approximation to the integral of analog input
values over time.
Disabled
Last maintenance date Records the date of the last maintenance in the Unit. 2002/1/1 (DRT2-AD04)
2004/1/1 (DRT2-AD04H)
Function Details Default
Scaling Performs scaling.
Scaling allows conversion of values between 0 and 6,000
into values using the industry unit required by the user. It
reduces the number of operations required in ladder pro-
gramming in the Master.
Disabled (0 to 6,000)
User adjustment Adjusts the output when an offset occurs in the output volt-
age or current.
Disabled
Cumulative counter (main-
tenance function)
Calculates an approximation to the integral of analog output
values over time.
Disabled
Error output value setting Sets the value output when a communications error occurs
for each output.
Low limit
Last maintenance date Records the date of the last maintenance in the Unit. 2002/1/1
Function Details Default
Moving average Calculates the average of the past eight temperature
input values, and produces a stable input value even
when the input value is unsteady.
Moving average disabled.
Scaling Performs scaling.
Scaling allows input values to be converted using default
upper and lower limits that can be set independently in
each Unit. The scaling function reduces the number of
operations requiring ladder programming in the Master
CPU Unit. Scaling also provides an offset function to
compensate for mounting errors in sensors and other
devices.
Disabled
0 to 28, 000
Peak/bottom hold Holds the maximum and minimum temperature input val-
ues.
Disabled
Top/valley hold Holds the top and valley temperature input values. Disabled
Rate of change Calculates the rate of change of temperature input val-
ues.
