BFM#0 :The current value of the input data for the channel specified with BFM#17 (lower 8bit data) is
stored. The current value data is stored by binary.
BFM#1:The current value of the input data (higher 4bit data) is stored. The current value data is stored
by binary.
BFM#17:b0⋅⋅⋅Channel (CH1,CH2) which does the analog to digital conversion is specified.

Photo-coupler isolation between analog and digital circuits.
No isolation between analog channels.
The blocks occupies either 8 input or output points
(can be either inputs or outputs)
Voltage input
At shipping, the unit is adjusted to a digital range of 0 to 4000 for an analog
voltage input of 0 to 10V DC. When using an FX
differing voltage inputs except 0 to 10V DC, it is necessary to adjust the
offset and gain.
