GlobalViewer (GV) is a set of Web pages (HTML, XML, JS) and graphics that are
loaded into the memory of an IPL T S interface. These pages provide an interface for
control of devices attached to the IPL T S interface. They communicate with the event
scripts running on the device, and the event scripts issue the commands and queries.
This communication between the Web pages and the event scripts occurs through
predetermined memory locations in the IPL T S interface. GV is initially created by
Global Configurator; however, it is possible to edit GV's HTML, XML, and JavaScript
files outside of GC. This edited GV is called "hard-coded" or manually generated
GlobalViewer.
HTTP is an acronym for the HyperText Transfer Protocol (HTTP), a Web protocol
based on TCP/IP, that is used to fetch HyperText objects from remote Web pages.
Internet Protocol (IP) is the protocol or standard used to send information from one
computer to another on the Internet.
IP address is a unique, 32-bit binary number (up to a 12 digit decimal number,
xxx.xxx.xxx.xxx) that identifies each sender and each receiver of information
connected to a LAN, WAN, or the Internet. IP addresses can be static (see Static IP) or
dynamic (see DHCP).
IP Netmask is a 32-bit binary number (12 digit decimal number, xxx.xxx.xxx.xxx)
used on subnets (smaller, local networks) to help the router determine which network
traffic gets routed internally to local computers and which network traffic goes out on
the Internet.
Media Access Control (MAC) Address is a unique hardware number given to
devices that connect to the Internet. When your computer or networking device
(router, hub, interface, etc.) is connected to the Internet, a table (see ARP) associates
the device's IP address to its corresponding physical (MAC) address on the LAN.
Pass-through allows control systems to work with the IPL T S interface, and provides
a link between two ports.
Ping is a utility that tests network connections. It is used to determine if the host has
an operating connection and is able to exchange information with another host.
Port number is a preassigned address within a server that provides a direct route
from the application to the Transport layer or from the Transport layer to the
application of a TCP/IP system.
Static IP refers to an IP address that has been specifically (instead of dynamically —
see DHCP) assigned to a device or system in a network configuration. This type of
address requires manual configuration of the actual network device or system and
can only be changed manually or by enabling DHCP.
Transmission Control Protocol/Internet Protocol (TCP/IP) is the communication
protocol (language) of the Internet. Computers and devices with direct access to the
Internet are provided with a copy of the TCP/IP program to allow them to send and
receive information in an understandable form.
Telnet is a utility available on most PCs that allows the computer system to
communicate with one of its remote users/clients. A user who wishes to access a
remote system initiates a Telnet session, using the address of the remote client. The
user may be prompted to provide a user name and password if the client is set up to
require them.
URL encoding allows you to send information and commands to the unit to change
its configuration or provide you with feedback.
Web Server resides on the IPL T S interface and provides storage of the default Web
pages, GlobalViewer, and your custom Web pages.
