2. Digital Values of Analog Output

• The digital values are stored in the special data registers (DT9096 to DT9103) by the board number selector of each
board.
• Be sure to use the F0 (MV) instruction to transfer the digital values into special data registers DT9096 to DT9103.
• The data is transferred from the special data registers at the time of I/O update in each scan.
Example: Transfer the digital value of data register DT100
to special data register DT9096 when X1 turns
ON.
• The digital data can be transferred into special data registers DT9096 to DT9103 using NPST-GR Software or FP
Programmer II.
Note:
• When the FP-M control board mode selector is set to the PROG. mode or an error occurs, the analog
output data becomes 0.
