2. Display of Analog Output
Value of analog output is displayed in hex on screen. The relationship between
displayed value and real value of analog output is:
Real value = ×20mA (current output mode)
or Real value = ×5V (voltage output mode)
As shown in Fig 5-21, the displayed value of AO1 is 0x0800, so the real value of
AO1 is (0x0800/4096) ×5V or (0x800/4096) ×20mA.

3. Parameter Setting
Take AXM-IO21 (AXM-IO2 module in logic NO.1) for example.
“Electrical quantities relative to AO1 (10C2H)” register: this register determines
which electrical quantity AO1 should be relative to. (see Chapter 6 for
explaination). For example, if this register is “0”, then AO1 is relative to
