7.4.8 Get Configuration File Information Block
Block 9000 or -9000: Get Configuration File Information
This block is used to request information from the processor about the
configuration file, in preparation for transferring the configuration file from the
processor to the module. It specifies the location in the configuration file to start
copying and sending the information.
Block 9000 or -9000: Request from Module to Processor
Offset Description
0 Read Block ID: 9000 or -9000 request for configuration file information from
processor
1 Write Block ID: 9000 or -9000 to be used by the processor in its next Write block.
Block 9000 or -9000: Response from Processor to Module
Offset Description
0 Write Block ID: 9000 or -9000 configuration file information
1 Module's slot number.
2 Size of the module's Input image to the processor.
3 Size of the module's Output image from the processor.
4 Status of configuration file.
5-6 These two registers contain the size of the configuration file in bytes.
7-8 These two registers contain the CRC for the configuration file.
7.4.9 Get Configuration File Block
Block 9001 or -9001: Get Configuration File Information
This block is used to request the configuration file from the processor. The
module returns the requested contents of the configuration file.
Block 9001 or -9001: Request from Module to Processor
Offset Description
0 Read Block ID: 9001 or -9001 request for configuration file from processor
1 Write Block ID: 9001 or -9001 to be used by the processor in its next Write block.
2-3 File offset: Offset of the first register in the configuration file to begin transferring data
from. If the size of the configuration file exceeds the block transfer size, the file is
transferred in multiple blocks, and the file offset tells the processor which part of the
configuration file is being requested by the individual block.
4-5 Number of bytes of the configuration file to include in next block
6-7 Copy of the data contained in registers 2 to 3.
