4.6.2 Saving the settings

The changed settings will not automatically become persistent, which means, they will not be stored permanently. For this purpose, an extra storage process needs to be carried out explicitly. This is carried out by writing the string "save" into the Index 102.

4.6.4 Restart

A restart is carried out by briefly disconnecting the sensor from the power supply. A restart can also be carried out by writing the string "boot" into the index 104. This command is not responded to by the sensor, as the sensor will be reinitialised immediately.

4.7 Example configuration process

The configuration message for all the following examples is the previously described PGN is

61184 (0x00EF00), in case of a successful request, the sensor responds by using the same

PGN.

4.7.1 Example: Read out profile number

All the settings of one device are combined in one profile. By reading of Index 0 of the Object

List (OL) the 2 bytes long profile number is sent, the HYDAC inclination sensor HIT sends the profile number 4. As described earlier, the reading of the entry in the Object List is possible directly without a prefixed command.

4.7.3 Example: Edit Baud rate

The Baud rate is set via a Baud rate index (see chapter 4.2.2

Setting of the Baud rate ). The

parameter is located on the OL Index 2 of the OL. In the example the Baud rate 500 kBit/s is set (Baud rate index 2). A new Baud rate will not be saved before the Baud rate index has been changed, saved and the device has been restarted. As an entry will be changed in the

Object List in this example, writing must be activated previously.

4.7.4 Example for a communication sequence

The following example is based on the communication between a sensor configured to the device address 1 and a sender using the device address 2 (i.e. controller or a PC with a CAN interface). The Baud rate of the sensor is changed to 500 kBit/s. For this purpose, the configuration mode has to be activated and afterwards, the Baud rate is changed, the changes in the OL will be permanently stored and finally, the sensor is restarted --> Please ensure that the Baud rate is also changed subsequently in the master.
