Virtual DTSW Bit
for Data Block #9
Virtual DTHW Bit
for Data Block #9
This rung monitors the DTCW and DTSW bits for Data Block #9. When a transfer of data using Data Block #9 is not in progress, copy up
to 128 words to the appropriate M-file location for Data Block #9 in the 1747-BSN module.
Virtual DTCW Bit for Data Block #9
Virtual DTCW Bit for Data Block #9 Virtual DTHW Bit for Data Block #9
Unlatch the virtual DTCW bit for Data Block #9 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 #9. When B3:7/8 has been unlatched, the module is ready for the next data transfer via Data Block #9.
Virtual DTSW Bit
for Data Block #10
Virtual DTHW Bit
for Data Block #10
This rung monitors the DTCW and DTSW bits for Data Block #10. When a transfer of data using Data Block #10 is not in progress, copy
up to 128 words to the appropriate M-file location for Data Block #10 in the 1747-BSN module.
Virtual DTCW Bit for Data Block #10
Virtual DTCW Bit for Data Block #10 Virtual DTHW Bit for Data Block #10
Unlatch the virtual DTCW bit for Data Block #10 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 #10. When B3:7/9 has been unlatched, the module is ready for the next data transfer via Data Block #10.
Virtual DTSW Bit
for Data Block #11
Virtual DTHW Bit for
Data Block #11
This rung monitors the DTCW and DTSW bits for Data Block #11. When a transfer of data using Data Block #11 is not in progress, copy
up to 128 words to the appropriate M-file location for Data Block #11 in the 1747-BSN module.
Virtual DTCW Bit for Data Block #11
Virtual DTCW Bit for Data Block #11 Virtual DTHW Bit for Data Block #11
Unlatch the virtual DTCW bit for Data Block #11 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 #11. When B3:7/10 has been unlatched, the module is ready for the next data transfer via Data
Block #11.
