The setting of AI (used as DI) function is the same as that of DI. For details, see the descriptions of DI setting.
The following figure takes AI input voltage as an example to describe the relationship between AI input voltage and
corresponding DI state.

VDO valid state selection
Default
00000
Setting
Range
Unit's digit: VDO1.
0
Positive logic valid
1
Reverse logic valid
Ten's digit: VDO2 0, 1 (same as unit's digit)
Hundred's digit: VDO3. 0, 1 (same as unit's digit)
Thousand's digit: VDO4. 0, 1 (same as unit's digit)
Ten thousand's digit: VDO5. 0, 1 (same as unit's digit)
VDO functions are similar to the DO functions on the control board. The VDO can be used together with VDIx to
implement some simple logic control.
⚫
If VDO function is set to 0, the state of VDO1 to VDO5 is determined by the state of DI1 to DI5 on thecontrol
