CAN Communication Plug-in Module
The location of the DIP-switches for selecting the
type of analog input and output signal and RS485 line
termination can be better visualized in
the analog inputs and/ or outputs with signals in current,
adjust switch S1 and the related parameters according to
table 1. For further details about the control connections
refer to Chapter 3 - Installation and Connection of
CFW500 user's manual.

Any other combination of switches is not
allowed.
The CFW500-CCAN Comunication Plug-in Module has
a 5-way plug-in connector for CAN communication with
the following features:
Allows communication CANopen and DeviceNet
„
in the product.
Galvanically isolated interface fron main power
„
supply with a differential signal, giving greater
resistance against electromagnetic interference.
allows connection of up to 64 devices on the
„
same segment. A larger number of devices can be
connected using repeaters. The maximum number
of devices that can be plugged into the network also
depends on the protocol used.
Maximum bus length of 1000 meters.
