Quick Start to set-up either of the following for a SLC Remote I/O System:
When commissioning a RIO network with a SLC system, use the following steps to ensure minimal time is used commissioning RIO system.
Making the Physical Connection
- Make sure the RIO network consists of the following:
- A Scanner, 1747-SN, located in main system with processor
- At least 1 1747-ASBAdapter
- Connect the scanner Scanner to other RIO devices in a daisy chain (serial) configuration.
- Ensure the maximum distance of network is:
- 10,000 feet at 57.6k baud, 5000 feet at 115.2k baud
- 2500 feet 230.4k baud.
- Ensure Belden 9463 cable is used
- Attach a 1/2 watt terminating resistor across line 1 and line 2 of RIO connectors at each end of network.
Setting Baud Rate on the 1747-SN Module
There are 4 positions available with 3 different selections possible.
Bits 01 – 02 Set the Baud Rate
| Setting | Baud Rate |
| 11 | 57.6K |
| 10 | 115.2K |
| 01 | 230.4K |
| 00 | 230.4K |
Set Dip Switches on the 1747-ASB Module
- Make sure that the Baud rate is set for the same as on the SN module
- Make sure that the Comp switch is set for Complimentary even when not implementing Comp/Primary System
- Make sure that Logical Address & Group Number do not conflict with any other devices on the network.
- Make sure I/O image size reflects the correct number of I/O modules connected to the ASB. (Round up if an odd number of modules are connected.)
- Make sure the RESERVED switch SW2-4 is in the ON position.

Configure SN in RSLogix500 User Program
- Doing a Read I/O Config will not address any remote I/O connected up to SN module - Only SN module will be found.
- Make sure that the SN module is configured as a Series B in order to support Block Transfer capabilities.
S/N configuration (Series A) must be deleted and re-entered to change to a Series B. (RSLogix500 does not distinguish between Series A and B in the I/O Config)
- Leave Scanned Input and Output Words at their default of 32.
- Leave M0 and M1 Lengths at their default of 3300.
- Leave G File Length at 3 unless Primary/Complimentary system is desired in which G File Length would be set to 5.
- Edit G File Config so it exactly matches all devices on the network. A Logical Rack consists of 8 I/O modules.
If the ASB I/O Image Size is set to 12, a Full Logical Rack and a 1/2 Logical Rack will be required.
- COMMs LED indicates a match or mis-match between ASB and G Data as follows:
- COMMs LED on the SN module blinks green if there is a mis-match.
- COMMs LED will be solid when there is a perfect match between G Data and actual configuration.
- A blinking RED LED indicates that SN module is not able to communicate with any device/
If this occurs, check:
- Cabling
and/or
- Configuration
Addressing
ASB does not consume any I/O module addressing, only a physical location in RIO chassis.
I/O Mapping
I/O mapping for any Discrete module within RIO system is as follows:
- I is used for an Input module
- O is used for an Output module
Refer to the table below for I/O mapping guidelines:
| Logical Rack 0 Group 0 | I/O:Slot of SN.0 |
| Logical Rack 0 Group 1 | I/O:Slot of SN.1 |
| Logical Rack 0 Group 2 | I/O:Slot of SN.2 |

| Logical Rack 2 Group 6 | I/O:Slot of SN.22 |
| Logical Rack 2 Group 7 | I/O:Slot of SN.23 |
| Logical Rack 3 Group 0 | I/O:Slot of SN.24 |
| Logical Rack 3 Group 1 | I/O:Slot of SN.25 |
| Logical Rack 3 Group 2 | I/O:Slot of SN.26 |
| Logical Rack 3 Group 3 | I/O:Slot of SN.27 |
| Logical Rack 3 Group 4 | I/O:Slot of SN.28 |
| Logical Rack 3 Group 5 | I/O:Slot of SN.29 |
| Logical Rack 3 Group 6 | I/O:Slot of SN.30 |
| Logical Rack 3 Group 7 | I/O:Slot of SN.31 |
Example
Input module in Logical Rack 1 Group 1 would be addressed as follows:
I:1.9
assuming that SN module is installed in slot-1.
Block Transfers
- Block Transfers are used to handle data from any specialty I/O module and map to any defined data table.
- Block Transfer instruction (BTW & BTR) were added to Series C SLC5/03, /04 and /05 processors.
- A KnowledgeBase document offers several BT examples and help setting up a BT instruction. Refer to AID 18461, titled Examples of Types of Block Transfers using SLC BTW and NTR Instructions.
A Series B SN module is required in order to use the BTW & BTR instructions. If you are using a Series A SN, you must replaced it with a Series B in order to use the BTW & BTR instructions.
