IO Modual
Real value = ×20mA (current output mode)
or
Real value = ×50V (voltage output mode)
As shown in figure 3-10, the displayed value of AO1 is 0x0800, so the real
value of AO1 is (0x0800/4096) ×5V or (0x800/4096) ×20mA.
Figure 3-1 shows the displayed value of analog output read by the utility
software.

3. Parameter Setting
Take AXM-IO21 (AXM-IO2 module in sub address 0) for example.
“AO output mode (10a9H)” register: this register determines the output
mode of analog output circuits. If this register is “0”, then the analog
output mode is 0 to 20mA. If this register is “1”, then the analog output
mode is 4 to 20mA. If this register is “2”, then the analog output mode
is 0 to 5V. If this register is “3”, then the analog output mode is 1 to 5V.
Displayed Value
