2 Setting Up the Hardware
2.1 Set-up and wiring
Manual: Section 2
The CAN 300 PRO is connected to the S7-CPU on the S7-300
mounting rail with the backplane bus connector supplied.
The DIP switch of the CAN 300 PRO has no function in this start-
up application because all settings are made in the project.
The CAN 300 PRO and the CANopen
®
device now have to be
connected on the CAN bus. Please pay attention to the
terminating resistors (120 ohms) between CAN High and CAN
Low at both ends of the cable and ensure that the three cables
CAN High, CAN Low, CAN-GND are not confused.
Manual: Section 3.2
The following table shows the pin assignment of the CAN 300
PRO module:

No terminating resistor
is integrated into the
CAN 300 PRO module.
Please note that the CAN 300 PRO module does not have a ready
installed terminating resistor. The terminating resistor must be
installed or activated in the connector.
