4.2.58 Intelligent output terminal setting
You can assign the functions described below to the intelligent
output terminals [11] to [15] (C021 to C025) and the alarm relay
terminal (C026).
The intelligent output terminals [11] to [15] are used for open-collector output, and the alarm relay terminal
is used for relay output.
You can select the a-contact or b-contact output for individual output terminals by using functions "C031" to
"C035" and "C036".
When "01" (3 bits) or "02" (4 bits) is specified for the alarm code output "C062" (see Section 4.2.65), the
alarm code output is assigned to output terminals 11 to 13 or output terminals 11 to 14 (AC0 to AC3),
respectively. Subsequently, the settings of "C021" to "C024" are invalidated.
