Glossary
Access Control:
An important security feature that limits access to Modbus
TCP, INCOM Passthrough, QCPort Passthrough and SNMP to Trusted Hosts.
It has functions that are similar to a security firewall.
AWG (M) American Wire Gauge
: Standard wire cross-section area
BACnet/IP
: A
communications protocol that provides read-only data from
Building Automation Systems (BASs), so that the PXG600E can be easily
integrated in a BAS alongside other BACnet/IP-capable devices.
Baud Rate:
A measure of the symbol rate; that is, the number of distinct
symbol changes (signalling events) made to the transmission medium per
second in a digitally modulated signal.
Bus:
A Bus represents a group of devices. It will often be used to indicate a
group of electrical monitoring devices connected to the same power Bus.
CH Studio:
An Eaton software program that supports configuration and
monitoring of QCPort devices.
Coordinated Universal Time: See UTC
.CSV file format:
A comma delimited format where each record is a single
line and each field in the record is indicated by a comma.
Device:
A device is the actual communicating unit that is connected to one of
the downstream communications ports of the PXG600E.
DHCP:
DHCP (Dynamic Host Configuration Protocol)
is a set of rules used by
communications devices such as a computer, router or network adapter to
allow the device to request and obtain an IP address from a server which has
a list of addresses available for assignment.
DIN Rail Mounting:
DIN is short for Deutsches Insitut für Normung eV, the
standards setting organization for Germany. A DIN rail is a mounting rail that
conforms to one of the standards defined by DIN. The Ethernet Switch may
be mounted using a DIN rail.
DNS IP Address:
Location of server that provides mapping of names to IP
addresses. It is a configuration setting that is provided by the IT manager.
DNS Server:
On the Internet, the Domain Name System (DNS) stores and
associates many types of information with domain names; most
importantly, it translates domain names (computer hostnames) to IP
addresses. It also lists mail exchange servers accepting e-mail for each
domain. In providing a worldwide keyword-based redirection service, DNS
is an essential component of contemporary Internet use.
EDS (Electronic Data Sheet):
A worksheet that defines supported data
parameters for a specific device.
Ethernet:
Ethernet is a large, diverse family of frame-based computer
networking technologies that operates at many speeds for Local Area
Networks (LANs). The name comes from the physical concept of the ether. It
defines a number of wiring and signaling standards for the physical layer,
through means of network access at the Media Access Control (MAC)/Data
Link Layer, and a common addressing format (Ethernet and Timing).
