5.6 Activation of the terminating resistor
If the gateway is used as the first or the last station in the bus communication, the fieldbus line has
to be terminated using a terminating resistor.
The BL20-E-GW-CO allows the activation of the resistors
R
T
using the last DIP-switch.
5.7 Storing of the BL20 station configuration
When configuring the BL20 station for the first time or changing the existing station structure (mod -
ule list), the current configuration must be transferred to the CANopen image of the BL20 gateway.
The configuration acceptance at this device is done via the DIP switches set to address 0.
Please proceed as follows:
1 Set the DIP switches at the gateway to a Node-ID  ”0”.
2 Switch on the system supply U
sys
and the field supply U
L
.
3 Set the Node-ID to “0“.
 The device stores the station’s configuration. This is indicated by the flashing of the “IOs“ LED.
 After the storage procedure, the “IOs“ LED shortly flashes orange and than stops flashing.  The
LEDs “Err“ and “Bus“ flash alternately red with 4 Hz due to the invalid Node-ID “0“ which is still set at
the gateway.
4 De-energize the gateway and set a Node-ID

“0“ at the gateway.

After power-on, the “IOs“ LED changes to green after approximately 2 seconds.

NOTE
The green "IOs" LED indicates that the current BL20 configuration matches the stored ref -
erence module list.
If the new configuration stored to the gateway does not match the old configuration, all
CANopen-parameters are set to their default values. Therefore it is necessary, to reload the
whole station parameterization.
