3.2.4.6 CAN Network (X4)
The CAN interface (Controller Area Network) is an isolated communication network with speed of up to 1 Mbaud,
seeing that the CANopen protocol is implemented in the SCA06 (see details in the CANopen manual). It is supplied
as standard from the factory with all the SCA06 devices. Its connection is done in connector X4, according to the
pinout presented in
Figure 3.17 on page 3-23
. It is recommended the use of a shielded cable with two pairs of
twisted wires. It is also necessary to provide a power supply of 24 Vdc (-15 %, +20 %) to the network connector.
A terminal resistor (120 Ω) must also be used in the extreme devices connected to the CAN network. This resistor
must be connected between pins 2 and 4 of the connector.
