CCA.
Channels
Divisions of radio frequencies supported in a wireless network.
Contract
An agreement between the system manager and a device in the network involving the
allocation of network resources by the system manager to support a communication
need of that device.
Comma Separated
Values
A method to store data that is separated by “comma”, so that it can be easily read and
processed by Win32 and Unix programs.
Device role
Device capabilities that will be accepted by the Security Manager.
DHCP
Dynamic Host Configuration Protocol – a method to automatically configure the IP
settings of a host connected in a LAN.
EUI64, EUI-64
The 64-bit address of a device in the network; it is a unique identifier usually set at the
manufacturing of the device.
Field
The geographic space that contains all the nodes of a wireless network.
Field device
A physical device designed to meet the rigors of plant operation that communicates via
DPDU’s conforming to the ISA100.11a protocol.
Gateway
An entity in the ISA100.11a network that serves as an interface between the ISA100.11a
network and a client.
Graph
(communication)
A collection of unidirectional interconnected devices, which defines a set of
communication paths between a source device and a destination device.
Graph (Topology)
A graphical representation of the network topology.
Input/output
A device with minimum characteristics required to participate in an ISA100.11a network
and which provides or uses data from other devices.
ISA100.11a
A low data rate and low power wireless communication protocol used for industrial
sensing and control applications. The protocol was standardized by the International
Society for Automation (ISA) and certified for compliance to the standard by the
Wireless Compliance Institute (WCI).
Link
A momentary or persistent interconnecting path between two or more devices for the
purpose of transmitting and receiving messaging.
Network Address
The 128-bit address of a device in the network.
Packet Error Rate
The ratio, in percent, of the number of lost packets (DPDU’s) to the total number of
packets sent by the selected device to its parent.
Process value
The quantity being controlled or the measurement value.
Provision
To update settings on an entity in order to prepare it for working in the network.
Revision
The device software revision related to vendor/model.
Router
A device that has data routing capability.
Security Manager
An entity in the ISA100.11a network which assigns the security keys that are required
