Acceptance of the BL20 Station Configuration
4.9 Acceptance of the BL20 Station Configuration
When making a new configuration of the BL20 station or an alteration of the existing station structure
(“Module list”), the current configuration must be accepted in the CANopen mirror of the BL20 gateway.
This is done through the configuration button between the two rotary encoding switches.
Pressing the set button with a pointed object for at least 2 seconds saves the current station
configuration in non-volatile memory. A hardware reset will then be carried out automatically. With this
reset, all the CANopen parameters will be restored to their default values, if the newly saved
configuration is different to the old one.
The actuation of the button is indicated by a rapid (4 Hz) green blinking of the "IOs" LED. After 2
seconds, the LED changes to yellow blinking at 4 Hz, thus indicating that the station configuration is
being saved. When the storage procedure is completed, the LED changes to a continuous green light.
Note
The green "IOs" LED indicates that the current BL20 configuration matches the stored
reference module list.
Attention
When saving the BL20 configuration, all the CANopen objects must be parameterized again,
if their parameter values differ from the default values. The complete parameterization of the
station must subsequently be reloaded into the BL20 station.
