2.4.3 CAN bus
The CIO module(s) can be configured as the only device on the CAN bus or together with an engine control-
ler (ECU) on the same CAN bus as shown in the below example. CIO module(s) can be placed together with
all the different engine protocols which are available in the AGC (both J1939 and CANopen), because the
CIO module will adapt to the baud rate on the CANline.
It is possible to connect up to three CIO modules of each type to one AGC.
A controller cannot have both CIO modules and Beckhoff modules connected
Below is an example that shows how the CAN bus can be connected:
