11 CAN module (optional)
The CAN module enables the AT40 door controller to be connected to a CAN bus. The interface is implemented according
to CiA Draft Standard 301, profile 417. The Service Tool must be used to set the power of command to CAN, so that the
controller can be addressed via the CAN bus. This deactivates the digital inputs. The factory settings of the major
parameters are:
Parameter
Command output
CANopen node ID
Baud rate
Door number
When the baud rate is set to "automatic", the CAN module automatically determines the baud rate on the CAN bus. To do
this, the CAN module must have received some valid CAN telegrams. The LED H3 flashes quickly at 5 Hz while the baud
rate is being automatically determined. All LED signals are listed in the following table.
LED signal (H3)
Off
Flashes briefly once per second
Goes out briefly once per second
On
Flashes rapidly
The connection can be made via the RJ45 socket (X15) and/or the terminal connector (X16). Each of the ferrites included in
the scope of delivery must be laid around a CAN line near the controller. The pin assignments are listed in the following
tables.
