7.2.9.1
Status output active state
The status output can be compared to an electrical relay that can function as make or break contact. For safety-
relevant applications, the operator will choose the break contact setting so that a power failure or failure of the
electronics can be detected like an alarm. In standard applications, the output is used as make contact.
The Status output state active state function allows the operator to define the behaviour of the status output.
