Note that all version checks are performed by REF542CONF before configuration
download. Therefore, the fault can occur only after a REF 542plus firmware
upgrade/downgrade or after FLASH configuration data corruption.
The following table describes signalling/handling of the configuration faults:

DSP (Digital Signal Processor)
The DSP supervision verifies correct DSP start-up and correct DSP working status
during normal operation.
The DSP start-up supervision verifies:
*
DSP version
It is used to verify communication at start-up and to check SW version
compatibility.
*
DSP Analogue Inputs calibration factors
The data is retrieved from the Analogue Input module. If the data is not present
or if it is corrupted, the system will be stopped because it is not able to guarantee
reliable measurements and safe protection executions.
*
DSP configuration
The DSP configuration is built by the MC from the Analogue Input and
Protections configuration. It is sent to the DSP that performs a consistency check
on it.
