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.
Holds the maximum and minimum analog input values.
Holds the top and valley values for analog input values.
Calculates the rate of change for analog input values.
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.
Detects disconnections of analog inputs. (Valid only for the
input ranges 4 to 20 mA and 1 to 5 V)
Adjusts the input when an offset occurs in the input voltage
or current.
Calculates an approximation to the integral of analog input
values over time.
Records the date of the last maintenance in the Unit.
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.
Adjusts the output when an offset occurs in the output volt-
age or current.
Calculates an approximation to the integral of analog output
values over time.
Sets the value output when a communications error occurs
for each output.
Records the date of the last maintenance in the Unit.
Calculates the average of the past eight temperature
input values, and produces a stable input value even
when the input value is unsteady.
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.
Holds the maximum and minimum temperature input val-
ues.
Holds the top and valley temperature input values.
Calculates the rate of change of temperature input val-
ues.
