1.3.6 Connecting the field bus
There is a bus plug on the CPV valve terminal for connecting it
to the Smart Distributed System. The following are connected
to this plug:
The two bus cables
The power supply ( +24 V DC and 0 V) for the bus inter
face and the internal logic
The hardware basis of the bus interface is the CAN bus. It is
typical for this bus that the bus interface is supplied with volt
age via the field bus plug.
Field bus socket
Connection to the bus is made via a branch line with a metal
4−pin M12 socket. Make sure that the cable screening/shield
and the metal field bus socket are connected (see also Ap
pendix A, Accessories).
Please note
Refer to your PLC manual or your bus interface manual for
information on the T−adapters and the maximum branch
line length permitted for your controller.
