▶ Select the XN300 slice module you want and then select <Add device>.
The XN300 slice module will be added to the "Devices" configuration struc-
ture.
A maximum of 32 XN300 slice modules can be added to the CANopen
device.
The device tree will now show all the devices.

If you are using analog modules, observe the following requirements:
• If you use the default mapping (index 0x6401/x) for analog modules, you
will need to enable PDO-based transmission for these I/O slice modules
by setting the value of object index 0x6423, subindex 0 to TRUE.
• Regulate the bus load on the CAN field bus
The following procedure is recommended in order to prevent the XN-
312-GW-CAN gateway from generating a heavy load on the CAN field
bus:

You can change the order of the XN300 slice modules in the
configuration structure by dragging and dropping them accord-
ingly.
