Virtual DTSW Bit
for Data Block #6
Virtual DTCW Bit for Data Block #6
Virtual DTHW Bit
for Data Block #6
Virtual DTHW Bit for Data Block #6
This rung monitors the DTCW and DTSW bits for Data Block #6. When a transfer of data using Data Block #6 is not in progress, copy up
to 128 words to the appropriate M-file location for Data Block #6 in the 1747-BSN module.
Unlatch the virtual DTCW bit for Data Block #6 when the comparable virtual DTSW bit is set by the 1747-BSN module to indicate that it has
received the last data via Data Block #6. When B3:7/5 has been unlatched, the module is ready for the next data transfer via Data Block #6.

Virtual DTHW Bit
for Data Block #7
This rung monitors the DTCW and DTSW bits for Data Block #7. When a transfer of data using Data Block #7 is not in
progress, copy up to 128 words to the appropriate M-file location for Data Block #7 in the 1747-BSN module.

Unlatch the virtual DTCW bit for Data Block #7 when the comparable virtual DTSW bit is set by the 1747-BSN module to indicate that it has
received the last data via Data Block #7. When B3:7/6 has been unlatched, the module is ready for the next data transfer via Data Block #7.
Virtual DTSW Bit
for Data Block #8
Virtual DTHW Bit
for Data Block #8
This rung monitors the DTCW and DTSW bits for Data Block #8. When a transfer of data using Data Block #8 is not in progress, copy up
to 128 words to the appropriate M-file location for Data Block #8 in the 1747-BSN module.
