The RS485 line polarizations and termination are settable
with jumper J2 as shown below.
See figure 15 to locate the jumper.

CAN
The CAN port is optional. Connect the cable for the CAN
field bus. The CAN bus is used to connect to the controller
devices that conform to the CANopen standard.
Considering that the CAN port is opto-isolated, it is not
necessary to disconnect the power to the device before
connecting it.
For the wiring of the line, use an approved cable.
Fasten the cable connector to that of the controller with the
appropriate screws.
Do not connect any filters other than the ones
described.

Warning: The CAN port has a line termination. If
the CPU module is the last or the first device on
the CAN line, you have to insert the termination
(120 Ω resistance, ¼ W, 5%) by setting jumper
J1 as shown in figure 23.
Remember that the CAN bus must be
terminated at both ends.
