FXST SERVICE TOOL
The purpose of this tool is to allow access to the application level build information calibrations, probes and overrides and
allow reprograming of the target application and view faults and certain con gurations. For uploading a new application see
section 9.
Any Value shown in the tool with a
Overrides are only temporary and return to the original after a power
will be maintained thru power -cycles, the exceptions are the calibration header information. Any changes to this region will
cause the ROM defaults to be loaded on the next power - cycle. For more information on Overrides and Calibrations consult the
help documentation of the respective blocks in Simulink®.
All projects will include the following information plus any Probes and Overrides added to the application:
_app_checksum: Application CRC32 value. The 32 bit Cyclic Redundancy Check is an error detection code that validates the
integrity of the application.
_calibrations: contains a calibration header with a CRC32 value for the calibrations, a parameter storing the size of the
calibration section, a counter indication how many times the values in the calibration has been changed and the GUID of the
application for compatibility check. After the header group all the user calibration parameter will be included in the variable
group.
For both tools the default node address of an HFX unit is 0, this can be con gured in the application and it has to match
the con gured value in the service tool. To con gure the FXST service too select the
To support more than 1 HFX unit in the CAN 1 channel the units must be programmed to have di erent node
addresses so that the tool can di erentiate between the units.
