Set using the DIP switch.
Not supported.
The following tables list the data processing functions that can be used with
Analog Slaves. Refer to 7-3-3 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
7-3-4 Calculating the Conversion Cycle.
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 requiring ladder program-
ming in the Master CPU Unit. Scaling also supports an off-
set function for compensating 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.
