The output LED 2 will switch on and you will hear the
relay contact switch to a closed state.
Now repeat the set/reset procedure of the last two
examples. You will receive messages with a reverse
behaviour of the output LED and relay contact. E.g. after
a ‘SET’ command, the LED goes off and the relay contact
switches to the open state and opposite.
An output configured as a closed contact can be
reconfigured to an open contact using the ‘Clear DO
configuration’ command (see 4.4.8) or using the opposite
configuration command.
Configure output as an open contact:
