Data Block Counters To help verify the functionality of the data transfer application
program, the 1747-BSN module has a counter for each data block that
can be transferred.
Each time that a block is transferred from the primary SLC 5/0x to the
primary 1747-BSN, the data block counter that corresponds to this
block is incremented once in the primary 1747-BSN. When the
secondary SLC 5/0x reads a block from the secondary 1747-BSN, the
corresponding counter is incremented once in the secondary
1747-BSN.
