5.2Address and baud rate

Up to 32 devices can be addressed in one CAN bus network branch and up to 127 devices in the extended network. Each device is identified by a unique address. The default node address for a device is 127.

The default baud rate is 125 kbaud.

Each device must be assigned its own node address, i.e. any given node address may be assigned only once in the network.

Setting address and baud rate The address is set directly at the device via parameter canAddr and the baud rate via parameter canBaud.

The baud rate must be the same for all devices in the fieldbus.

5.3Commissioning the fieldbus network

5.3.1Starting fieldbus mode

Configuration with SyCon Note on using the Hilscher configuration software SyCon:

Do not change the setting Geräteprofil (value = 0) in the

Knotenkonfiguration dialog box!

If this value is changed, communication with the drive will no longer work. However, the setting cannot be reset to the initial value.

To restore communication with the product:

Click the Knoten BootUp button in the Knotenkonfiguration dialog box.

Click Prüfe Knoten Type and Profile in the Knoten Auf- schaltreihenfolge dialog to skip this step.

Testing fieldbus operation After correct configuration of the transmission data, test fieldbus opera- tion.

This requires installation of a CAN configuration tool that displays CAN messages. The acknowledgement from the product is indicated by a boot-up message:

Switch the power supply of the product off and on again.

Observe the network messages shortly after switching on the device. The positioning controller sends a 1 byte boot-up message after initialization of the bus: 128 (80h)+node-Id.

With the node address factory-set to 127 (7Fh), boot-up message 255

(FFh) is transmitted via the bus. The drive can then be put into operation 11.2008 via NMT services.
