The DGFC communicates to the DRIVE through a device called DPRAM. This device allows the
write or read from the parameters of
DRIVE, and consequently to condition its functioning. In DPRAM
there are various communication structures with different functioning modes.
The structure piloted by the IDA block carries out a reading operation of DGFC from the
parameters.
The maximum number of parameters to be controlled by this structure is 10. The reading of the parameters
occurs in an asynchronous way compared to the regulation cycle.
The communication structure is composed of ten slots. Inside each
slot
3 data are contained:
l
Identifier of DRIVE parameter
l
T Y P E
Type of DRIVE parameter
l
VALUE
Value to be read from the parameter specified by
During the transition of DGFC from
the communication structure is configured:
l
DGFC copies
parameters in the
field of the respective slots.
l
DGFC requires the
to carry out the configuration of the communication structure.
l
The
analyses the parameter identifiers in the
field and if it finds them in compliance with
each other, it writes the type of the required parameter in the
TYPE
field. The TYPE field will be used
during the communication to perform the automatic conversion of data.
