Glossary
The following terms are used throughout this manual. Refer to the Allen-Bradley
Industrial Automation Glossary, Publication Number AG-7.1, for a complete guide to Allen-Bradley technical terms.
Adapter
−
Any physical device that is a slave on the RIO link.
Adapter Image
−
That portion of the scanner image assigned to an individual adapter.
ASB Module
−
The Catalog Number 1747-ASB, 1771-ASB, or 1794-ASB
Remote I/O Adapter Module. The ASB module is an adapter.
ASB Module Chassis
−
The chassis directly controlled by the ASB module. This includes the remote chassis and (if installed) two remote expansion chassis when using the 1747-ASB.
Block Transfer (BT)
−
See RIO Block Transfer.
Block Transfer Read (BTR)
−
A form of block transfer that occurs when a remote device transfers data to the SLC processor.
Block Transfer Write (BTW)
−
A form of block transfer that occurs when the
SLC processor transfers data to a remote device.
Complementary I/O
−
Functionality that allows you to maximize I/O usage by pairing up I/O data from a primary and complementary chassis.
Discrete I/O
−
An input or output device that has corresponding bit locations in the scanner’s input or output file.
Discrete I/O Module
−
An I/O module used to sense or control two–state (ON/
OFF) devices.
Data Transfer Control Word (DTCW)
−
This word is M0:s.3410 (where s=slot number of the BSN) and is used by the primary processor to initiate data transfers to the primary BSN. Eventually the primary processor initiates data transfers to the secondary BSN over the HSSL, and then to the secondary processor.
Data Transfer Handshake Word (DTHW)
−
This word is M0:S.3411 (where s=slot number of BSN) and is used by the secondary processor to inform the secondary BSN that it has received the latest data block and is ready for the next data block.
Data Transfer Status Word (DTSW)
−
This word is M1:s.3410 (where s=slot number of BSN and is used in both the primary and secondary systems to affect the transfer of data on the HSSL.
212
Glossary
Extended Node Capability
−
Functionality that allows you to use an
82 Ohm termination resistor at both ends of the RIO link for all baud rates. This functionality also allows for up to 32 adapters to be connected to the RIO link.
G file
−
The SLC file used to configure the scanner. You enter configuration information into this file during SLC processor programming. This file is loaded to the scanner by the SLC processor upon entering run mode.
High-Speed Serial Link (HSSL)
−
2 Mbit/second link between primary and secondary BSN modules to provide the secondary SLC processor with input, block transfer, and user retentive data. Network status and control information are also transferred between BSN modules on this link.
Inhibit
−
A function by which the scanner stops communicating with a logical device. The logical device considers itself inhibited if it does not receive communications from the scanner within a certain period of time.
Input file
−
The scanner’s input image file that is updated during the
SLC processor input scan.
Local Expansion Chassis
−
A chassis that is connected to a local
SLC chassis using a 1747-C9 (91.4 cm [36 in.]) or 1747-C7 (15.2 cm
[6 in.]) cable.
Local SLC Chassis
−
The chassis that contains the SLC processor and scanner.
Logical Device
−
Any portion of a logical rack that is assigned to a single adapter. Adapters may appear as more than one logical device.
Logical Group
−
A logical group consists of one input and one output word within a logical rack. A word consists of 16 bits, each bit represents one terminal on a discrete I/O module.
Logical Rack
−
A fixed section of the scanner image comprised of eight input image words and eight output image words.
Logical Slot
−
A logical slot consists of one input and one output byte within a logical group. A byte consists of 8 bits, each bit represents one terminal on a discrete I/O module.
M files
−
The SLC M0 and M1 data files that reside in the scanner. M files contain RIO network status (M1) and control (M0) information.
The contents of these files can be directly accessed by your application program. Also, the M files are used to control and monitor
RIO block transfer operations.
Publication 1747-6.22
Glossary
213
Module Status Word (MSW)
−
This word is M1:s.3401 (where s=slot number of the BSN) and is used to monitor the status of the
1747-BSN itself and its counterpart in the remote system.
Output file
−
The scanner’s output file that is updated during the
SLC processor output scan.
Remote Chassis
−
The chassis containing an ASB module and connected to the local SLC chassis via the RIO link.
Remote Expansion Chassis
−
A chassis that is connected to a remote chassis using a 1747-C9 (91.4 cm [36 in.]) or 1747–C7
(15.2 cm [6 in.]) cable.
Reset, Adapter Decide
−
Commands sent by the scanner to a logical device during an RIO discrete transfer. These commands instruct the logical device to reset all of its discrete outputs if hold last state is not selected, or to hold all of its discrete outputs in their last state if hold last state is selected.
Reset, Adapter Reset
−
Commands sent by the scanner to a logical device during an RIO discrete transfer. These commands instruct the logical device to reset all of its discrete outputs, regardless of the hold last state selection.
RIO Block Transfer
−
The exchange of up to 64 words of data between the scanner and a remote device. RIO block transfers only occur if you program them in your processor control program.
RIO Discrete Transfer
−
The exchange of image data between the scanner and adapter. RIO discrete transfers occur continuously whenever the scanner and adapter are communicating on the RIO link.
RIO Link
−
An Allen-Bradley communication system supporting high-speed serial transfer of Remote I/O (RIO) control information.
This link consists of one master and one or more slaves.
RIO Link Device
−
Refers to any Allen-Bradley or licensed third party product that connects to the RIO link as an adapter or slave device.
Scanner
−
The Catalog Number 1747-SN, Remote I/O Scanner, which is the master on the RIO network.
Scanner Image
−
The data table area within the scanner, used to exchange I/O information between the scanner and all the adapters on the RIO link. The scanner image is a portion of the SLC processor image.
Publication 1747-6.22
214
Glossary
SLC Chassis
−
A physical SLC rack that houses SLC processors and
1746 and 1747 I/O modules.
SLC Processor
−
The processor that controls the SLC chassis in which the scanner is installed.
Slot
−
The physical location in any SLC chassis used to insert I/O modules.
Specialty I/O Module
−
An I/O module other than a discrete I/O module (e.g., an analog module).
System Status Word (SSW)
−
This word is M1:s.3400 (where s=slot number of BSN and is used to monitor the status of the entire backup system.
