BootP
BootP (Bootstrap Protocol) is a low-level protocol that provides configurations to
other nodes on a TCP/IP network. BootP configuration files let you automatically
assign IP addresses to an Ethernet module (you can also obtain subnet masks
and gateway addresses from BootP).
bps
Bits per Second. A measure of data transmission speed across a network or
communications channel;bps is the number of bits that can be sent or received
per second.
Bridge
A node between two similar communication subnets where protocol translation is
minimal.
C
Channel
One portion of the available radio spectrum that all devices on a wireless network
use to communicate. Changing the channel on the access point/router can help
reduce interference.
CIP
Control and information protocol, the EtherNet/IP application layer uses the
producer/consumer networking model. In this model one producer broadcasts
(multicasts) the data once to all the consumers. All consumers see the data
simultaneously and may choose whether to consume (receive) the data or not.
Delivery time is consistent, no matter how many consumers there are.
Client
A client is software program, or the device on which that program runs, that
makes requests for information from a software program, or the device on which
that program runs, in a client-server relationship.
A Client on an Ethernet network is equivalent to a Master on a serial network.
Configuration PC
A Computer that contains the configuration tools for the ILX34-AENWG.
Connection
The communication mechanism from the controller to another module in the
control system, usually used to exchange I/O data.
consumer
A destination device in the CIP networking model. See CIP.
