1.3 Data Processing Functions
1.3 Data Processing Functions
1.3.1 Analog Input
For analog input, there is the “General sampling function,” “Averaging function,” and
“Offset changing function.”
1.3.1.1 General Sampling Function
The analog input values are converted point by point and the digital values are stored
in converted value area (input contact area).
1.3.1.2 Averaging Function
From the data sampled according to the number of times set in the shared memory, the
average value of the data (excluding the maximum and minimum values) is stored in
the conversion value area (input contact area). If the number of times is 2 or less, or
outside of the allowable range (65 or more), the general sampling function is used.
The time for the average value to be stored in the conversion value area changes
drastically depending on the number of inputs used, the used input range, and the
average number of times.
For detailed information section 6.3
1.3.1.3 Offset Changing Function
The conversion data for the all ranges of the input channels is offset by the amount set
in the shared memory (range: -2048 to +2047) and stored in the conversion value area
(input contact area).

1.3 Data Processing Functions
1.3.2 Analog Output
For analog output, there is the “Analog output hold function.”
1.3.2.1 Analog Output Hold Function
Non-hold, hold (final value during RUN mode), and hold (any value) for the analog
output during the FP2 CPU unit PROG. mode can be set by the shared memory
settings.
For hold (final value during RUN mode), the analog output value is held corresponding
to the final digital data written during the RUN mode before changing to the FP2 CPU
unit PROG. mode.
Forhold(anyvalue),theanalogoutputvalueisheldcorrespondingtotheholddata(any
value) set in the shared memory when changing to the FP2 CPU unit PROG. mode.
Note When set to either hold (final value duringl RUN mode) or hold
(any value), the each analog output is held during stops in
operatiohn due to FP2 CPU unit hardware malfunctions or
operation delays.
