7-140 RIO Block Transfer Publication 1747-6.22 Rung 2:3 | Copy the BTW status area to an integer file only when a BTW is in progress.

When a BTW is complete, the done or error bit is set. The ladder program must then unlatch the enable bit, then wait for the SN module to turn off the done/error bit before | another BTW to the same M-file location can be initiated. This completes one BTW cycle. | | | | VIRTUAL | | BTW DONE CHECK BTW | | BIT STATUS | | N7:64 B3 | |-+----]/[-----+-------------------------------------------------------(U)-----| | | 13 | 3 | | | | | | | | | | | VIRTUAL | | | | BTW ERROR | | | | BIT | | | | N7:64 | | | +----]/[-----+ | | 12 |
RIO Block Transfer 7-141 When a BTR successfully completes, buffer the BTR data and unlatch both the BTR virual enable bit and the BTR | pending bit. Also, latch the bit that continues checking the BTR status until the SN module turns off the done bit. | | | | VIRTUAL | | BTR DONE | | BIT BTR DATA | | N7:60 +COP---------------+ | |----] [------------------------------------------------+COPY FILE +-+-| | 13 | |Source #M1:1.110| | | | | |Dest #N7:0| | | | | |Length 10| | | | | +------------------+ | | | | | | | | | | | | | | | | BTR | | | | PENDING | | | | B3 | | | +----(U)---------------+ | | | 0 | | | | | | | | | | | | VIRTUAL | | | | BTR ENABLE | | | | BIT | | | | N7:50 | | | +----(U)---------------+ | | | 15 | | | | | | | | | | | | | | | | | | | | | | | | CHECK BTR | | | | STATUS | | | | B3 | | | +----(L)---------------+ | | 2 | Rung 2:6 When a BTR unduccessfully completes, buffer the error code and unlatch the BTR enable bit and the BTR pending bit.
