The SLC controller communicates with the block I/O using a Distributed
I/O Scanner module (cat. no. 1747–DSN). The scanner can address up to 7
blocks using an SLC 5/01 Controller, and up to 30 blocks using an SLC
5/02 Controller. When used with the Distributed I/O Scanner module,
block addresses must be contiguous. The actual number of blocks to which
the scanner module will communicate is determined when programming
the SLC controller.
Refer to the 1747–DSN Scanner module user’s manual for more
information.
In this chapter you learned how to identify and set the configuration
switches on the block.
