1. a) How many module groups are in a full RIO rack? b) What is the rack number range for a 1747-SN scanner module? c) List the three addressing modes available in SLC500 RIO systems? d) List the qty of racks that an 8 I/O slot chassis would consume for each of the addressing modes outlined in (c). e) What is the maximum cable distance of a RIO system? f) What type of cable is used to interconnect RIO systems? (qty of conductors, shield/unshielded, part number) g) Where are terminating resistors installed on a RIO communication cable? Why? h) How many digital output points can a 1747-SN RIO scanner module control? i) Give an example of a RIO address and clearly explain the structure of the RIO address (fig 2-12, unit 2) j) Which rack # and I/O group corresponds the word 21 of the 1747-SN scanners output image? k) List the scanner output word that corresponds to rack 2, I/O group 4 for a 1747-SN scanner installed in local slot 5. 1) A 1747-ASB RIO Adapter module is located 1000 feet away from the SLC 5/04 processor. Briefly explain how you could use the LED's on the adapter to determine which mode the SLC 5/04 is in (program or run), so you do not have to walk back the 1000 feet to the processor.
