As blocks are transferred between the module and the processor, each block
contains block identification codes that define the content or function of the block
of data transferred. The control blocks used by the module are displayed in the
following table.

Block identification codes 9901 to 9999 are used for special control blocks to
control the module. Each of these blocks is discussed in the following topics.
Normal Data Transfer Blocks
These data are transferred through read (input image) and write (output image)
blocks. Refer to Module Configuration for a description of the data objects used
with the blocks and the ladder logic required. The following topics discuss the
structure and function of each block.
Input Data (3x Register Data)
These blocks of data transfer information from the module to the Quantum
processor. The following table describes the structure of the input image.
Offset Description Length
0 Sequence Counter 1
1 Block ID 1
2 to 63 Command Response Data 62
64 to n Read Data 0 to 3999
Output Data (4x Register Data)
These blocks of data transfer information from the Quantum processor to the
module. The following table describes the structure of the output image.
Offset Description Length
0 Sequence Counter 1
1 Block ID 1
2 to 63 Command Data 62
64 to n Write Data 0 to 3999
