2. When Di external dry contact is connected, vg814 can provide the same pull-up
level as the power supply voltage internally, and the pull-up resistance is 20K
Ω.
3. When do is used as open drain output, the typical perfusion current can reach
450mA.
4. When do pull-up is used as output, it can output high-level signal. The open
circuit test voltage is the same as the power supply voltage. The pull-up
resistance is 20K Ω and has no load capacity.
8.2.1 IO link mode
Wet node link mode, need config : DI1 disable pull up use CLI. Off is 0, On is 1.
Dry node link mode, need config : DI1 pull up use CLI. On is 1, Off is 0.
