This rung copies the "new" Data Block #4 data from the secondary 1747-BSN to a file within the secondary processor. When the Copy is
complete, the DTHW (Data Table Handshake Word) bit for Data Block #4 (B3:4/3 = M0:1.3411/3) must be set to inform the secondary
1747-BSN that the secondary processor has received the latest Data Block and is now ready for the next block of data via Data Block #4.

This rung copies the "new" Data Block #5 data from the secondary 1747-BSN to a file within the secondary processor. When the Copy is
complete, the DTHW (Data Table Handshake Word) bit for Data Block #5 (B3:4/4 = M0:1.3411/4) must be set to inform the secondary
1747-BSN that the secondary processor has received the latest Data Block and is now ready for the next block of data via Data Block #5.

This rung copies the "new" Data Block #6 data from the secondary 1747-BSN to a file within the secondary processor. When the Copy is
complete, the DTHW (Data Table Handshake Word) bit for Data Block #6 (B3:4/5 = M0:1.3411/5) must be set to inform the secondary
1747-BSN that the secondary processor has received the latest Data Block and is now ready for the next block of data via Data Block #6.

This rung copies the "new" Data Block #7 data from the secondary 1747-BSN to a file within the secondary processor. When the Copy is
complete, the DTHW (Data Table Handshake Word) bit for Data Block #7 (B3:4/6 = M0:1.3411/6) must be set to inform the secondary
1747-BSN that the secondary processor has received the latest Data Block and is now ready for the next block of data via Data Block #7.
