Connection with M12 adapter (reverse key coded)
With adapter (type: FBA−2−M12−5POL−RK, part no. 533118),
you can connect the CPV Direct to the field bus via an M12
plug connector. The plug connectors have an inverted mech
anical coding (reverse key or B−coded), to avoid confusion
between incoming and continuing connections.
You can disconnect the M12 adapter from the CPV Direct
without interrupting the bus cable (T−TAP function).
Connection to the field bus is made with a 5−pin M12 plug
with PG9 screw connector. Use the second connection socket
for the continuation of the field bus.
