4.4.3 Writing of Digital Data for Output (12-bit Mode)

The analog I/O unit (FP0R-A42/A21) writes data for conversion as the output switching flags
are not contained in the 12-bit mode.
 I/O allocation (12-bit mode)
WY3 WY2
CH1 data CH0 data
 Writing data for conversion
• The analog I/O unit writes the analog output digital data of a maximum of 2 channels to two
memory areas (WY2/WY3) by user programs.
•
Always insert a program which checks the upper and lower limits to make
written digital values be within the allowable data ranges referring the
programs described on the following pages.

 Sample program (12-bit mode: -10V to +10V range)
The following program shows the case that the data of DT0 to DT1 is converted and output to
the CH0 to CH1 of the first expansion analog I/O unit (FP0R-A42/A21).
