}
The module will detect an open circuit between outputs O0+ and O0.
}
The result of open circuit detection is signaled to the head module via a virtual input.
The result is available within the user program:
}
No open circuit detected: Status bit set
–
Open circuit detected: Status bit not set
}
Loads over 3 kOhm may mistakenly be detected as an open circuit.
