4. A/D conversion time is the time it takes for an analog signal to be stored in
memory as converted data after it has been input. It takes at least one cycle
before the converted data is read by the CPU Unit. D/A conversion time is
the time required for converting and outputting the PC data. It takes at least
one cycle for the data stored in the PC to be read by the Analog Output Unit.
By executing an I/O refresh, the conversion time may be extended by an
additional 0.3 ms approximately.
5. The default setting is for current output (load resistance: 250
Ω
). When
using voltage output, or when using current output with a load resistance
other than 250
Ω
, perform the offset and gain adjustment as required.
