Glossary
This glossary defines terms used throughout this manual or that appear in the web interface of
the Smart Wireless Gateway.
Term
Definition
Access
Control List
A list of all devices that are approved to join the network. Each device will also have a
unique join key. Also referred to as a white list.
Active
Advertising
An operational state of the network manager that causes the entire wireless field
network to send messages looking for new or unreachable devices to join the network.
Baud Rate
Communication speed for Modbus RTU.
Burst Rate
The interval in which a wireless field device transmits measurement and status data to
the Gateway. Same as Update Rate.
Certificate
A digital signature used to authenticate a client/server while using encrypted
communications.
Connectivity
Typically refers to a combination of communication statistics and link reliability of a
wireless field device. May also refer to the connection between the Gateway and the Host
System.
Device ID
A hexidecimal number that provides unique device identification.
DHCP
Dynamic Host Configuration Protocol: Used to automatically configure the TCP/IP
parameters of a device.
Domain
A unique designator on the internet comprised of symbols separated by dots such as:
this.domain.com
Gateway
Refers to the Smart Wireless Gateway.
HART Tag
The device’s electronic tag that the Gateway uses for all host integration mapping. Refers
to the HART long tag (32 characters, used for HART 6 or 7 devices) or the HART message
(32 characters, only used for HART 5 wired devices connected via a WirelessHART
adapter)
Host Name
A unique designator in a domain associated with the IP address of a device such as:
device.this.domain.com. In that example the hostname is device.
HTML
Hyper Text Markup Language: The file format used to define pages viewed with a web
browser.
HTTP
Hyper Text Transfer Protocol: The protocol that defines how a web server sends and
receives data to and from a web browser.
HTTPS
HTTP over an encrypted Secure Sockets Layer (SSL)
Join Failure
When a wireless field device fails to join the WirelessHART network. Most join failures are
due to security reasons (missing or incorrect join key, not on access control list, etc.)
Join Key
Hexadecimal security code that allows wireless field devices to join the wireless field
network. This code must be identical in the device and the Gateway.
Latency
The time from when a message leaves a wireless field device until it reaches the Gateway.
Netmask
A string of 1's and 0's that mask out or hide the network portion of an IP address leaving
only the host component.
Network I.D.
Numeric code that associates wireless field devices to the Gateway. This code must be
identical in the device and the gateway.
