6.13 Configuring the Node ID / baud rate

DIP switches for
colour configura-
tion

DIP switches for ad-
dress+ baud rate

8 DIP switches are available for configuration:

• DIP switches 1 to 6 for the Node ID (büS/

CANopen address)

• DIP switches 7 to 8

for the baud rate

Please note:

Values fixed by DIP switches invalidate software-
configured values!

Fig. 8:

Position of the DIP switches

6.13.1 Setting the baud rate

Adjustment of the control head to the baud rate of the network:

Baud rate

DIP 7

DIP 8

125 kbit/s

off

250 kbit/s

off

500 kbit/s

off

Factory settings:

software configurable baud rate

with pre-setting: 500 kbit/s

*) Via software (Bürkert Communicator) configurable baud rates: 50, 125, 250, 500, 1000 kbit/s;

via software (CANopen/SPS)

additionally

configurable baud rates: 10, 20, 100 kbit/s

(see chapter “6.19.4 Access to further parameters (cyclic and acyclic)”).

Please note:

The baud rate of all network participants (control heads, gateway, possibly other products) must
correspond to each other!

To apply any changes to settings, restart the device!

If the settings are changed by actuating the DIP switches, these changes will not take effect until the device
is restarted! For a restart:

• trigger a restart command via Bürkert Communicator or

• briefly disconnect the control head from the power supply and reconnect or

• switch the power supply off/on or

• transmit an appropriate reset message.

Special characteristics for configuration of the “software configurable baud rate”:

• Hardware configured values (via DIP switch) have priority over software configured values!

• If the DIP switches were set to “software configurable baud rate”, the current baud rate is still valid - until

a new baud rate is selected via software. Then restart the device!

Example:

Resetting the factory setting without using the software:

Set DIP7+8 to 500 kbit/s. Restart device. Then set DIP7+8 to “software configurable”. Restart device.
