This rung copies the "new" Data Block #12 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 #12 (B3:4/11 = M0:1.3411/11) 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 #12.
This rung copies the "new" Data Block #13 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 #13 (B3:4/12 = M0:1.3411/12) 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 #13.
This rung copies the "new" Data Block #14 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 #14 (B3:4/13 = M0:1.3411/13) 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 #14.
This rung copies the "new" Data Block #15 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 #15 (B3:4/14 = M0:1.3411/14) 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 #15.
