14.2.64. Registers CAL_XXX
These registers contain several calibration constants for current generation, current measurement,
voltage measurement and temperature measurement.
Factory values can be overridden but the saving of the new values in non-volatile memory is not
allowed unless valid unlock codes are entered in registers
CAL_UNLOCK_CODE0
and
CAL_UNLOCK_CODE1
.
14.2.65. Registers CAL_UNLOCK_CODE[0-1]
These registers contain unlock codes to allow saving in non-volatile memory of the various
calibration constants used for current generation, current measurement, voltage measurement and
temperature measurement.
14.2.66. Register BOARD_COMMAND
This register is used to execute special actions. Allowed values are listed below. Avoid operation with
non-listed values.
•
When 0 no action to perform
•
When 1 register file is read from non-volatile memory (current contents will be overridden)
•
When 2 register file is written to non-volatile memory (current contents will not be affected)
•
When 3 the controller is rebooted
•
When 4 the voltage autodetect is started if the DC/DC converter operates in autodetect
voltage mode (register
CONVERTER_MODE
set to 1). This setting has no effect if the DC/DC
converter operates in fixed voltage mode (register
CONVERTER_MODE
set to 0)
Changes to the register file are saved in non-volatile memory only when a specific command is
issued to the controller using this register. The register is automatically set back to zero after the
requested action has been completed.
14.3. Operation with a web browser
The controller has an Ethernet interface that allows it to be easily configured using a web browser.
The default configuration uses the static IP address 192.168.0.32. It is possible to change this factory
configuration using either the serial RS485 interface with Modbus/RTU or the Ethernet interface with
Modbus/TCP, Modbus/UDP or the web pages. The factory settings can be restored using the INIT
button (see
for a description of the INIT button functionalities).
For more information about the Modbus/RTU, Modbus/TCP and Modbus/UDP protocols and
the
Modbus register file please refer to
To access the web pages of the controller it is necessary to connect the controller to a PC using a
standard Ethernet cable and to configure the PC to operate in the same local network used for the
controller. The web interface can then easily be accessed by entering the controller IP address in
the browser (factory IP address is 192.168.0.32). Microsoft Edge, Google Chrome and Mozilla
Firefox are all supported web browsers. Other web clients have not been tested.
The following paragraphs detail the web interface of the controller.
14.3.1. Main page and navigation menu
Once the web browser is successfully connected to the controller, the main web page of the controller
will be displayed (see the image in
