Overview of Analog I/O Units
Section 5-1
5-1-3
List of Data Processing Functions
The following tables list the data processing functions that can be used with
Analog I/O Units. Refer to
for details on func-
tions and setting methods.
GRT1-AD2 Analog Input Units
GRT1-DA2V/GRT1-DA2C Analog Output Units
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
By reducing the number of input conversion points, the con-
version cycle speed can be increased. For details, refer to
5-4-4 Calculating the Conversion Cycle.
2-point conversion
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 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.
0 to 6,000
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 (i.e., value for peak, bottom, top, valley,
rate of change) with the four set values HH, H, L, and LL,
and indicates 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.

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.
