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