Analog Output Units Section 7-3
Allocation of Output
Words
Four output words are allocated, beginning from the first word following the
last I/O word allocated to the CPU Unit or already-connected Expansion I/O
Unit or Expansion Unit.
Writing the Range Code Write the output use and the range code to words n+1 and n+2. The D/A con-
version will start when the set data is transferred from the CPU Unit to the
Analog Output Unit.
â–  Range Code
• The Analog Output Unit will not start converting analog I/O values until the
range code has been written. The output will be 0 V or 0 mA.
• From when the range code has been written until data in the analog out-
put convertible range is written, 0 V or 0 mA will be output in the 0 to 10 V,
-10 to +10 V, and 0 to 20 mA ranges, and 1 V or 4 mA will be output in the
1 to 5 V and 4 to 20 mA ranges.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
