4.2.59 Intelligent output terminal a/b (NO/NC) selection<br />
The intelligent output terminal a/b (NO/NC) selection function<br />
allows you to specify a-contact or b-contact output for each of<br />
the intelligent output terminals [11] to [15] and the alarm relay<br />
terminal.<br />
The intelligent output terminals [11] to [15] are used for open-collector output, and the alarm relay terminal<br />
is used for relay output.<br />
