The SLC controller communicates with the block I/O using a Distributed
I/O Scanner module (cat. no. 1747–DSN) or an RIO Scanner module (cat.
no. 1747–SN). The 1747–DSN scanner can address up to 7 blocks using an
SLC 5/01 Controller, and up to 30 blocks using an SLC 5/02 Controller.
The 1747–SN scanner, only used with the SLC 5/02 processor, can address
16 blocks. When used with the Distributed I/O Scanner module, block
addresses must be contiguous. The actual number of blocks to which the
1747–DSN scanner module will communicate is determined when
programming the SLC controller.
Refer to publication 1747–NM004 Series A, “Distributed I/O Scanner,“
and publication 1747–NM005 Series A, “RIO Scanner” for complete
information on switch settings and addressing of the block I/O.
