Description |
Application |
| CT
Server™ |
The
Java-based engine that interfaces CTC controllers with the network. |
Provides
bidirectional Internet/Intranet access to parameters and data in CTC
controllers. |
| HTTP
(Hypertext Transfer Protocol) |
A
simple extensible protocol used for data exchange over the Internet.
Browsers use HTTP to communicate with servers. |
Used
to serve static pages as well as diagnostics and monitoring applets
from CT Server. Enable of many of the other technologies within CT
Server. |
| Modbus/TCP |
A
protocol used for Modbus messaging in an Internet or Intranet environment. |
Users
can exchange and integrate data with other devices conforming to Modbus/TCP
protocol. |
| RMI
(Remote Method Invocation) |
A
Java-based messaging protocol standard that can interrogate, change
and control one or more CTC controllers. |
Users
can view and edit controller parameters via Jav-based applets embedded
into web pages or via WebMon™, CTC's Web-based monitoring and
control application. This makes remote diagnostics, upgrades, and
customization possible. |
| SOAP
(Simple Object Access Protocol) |
Based
around XML, SOAP is a lightweight, cross-platform protocol for data
exchange and control in a distributed environment. It can interrogate,
change and control one or more CTC controllers. |
SOAP
eanbles applications running on different platforms to exchange data
bidirectionally. It extends XML's capabilities to be "read/write."
Because SOAP uses HTTP, it is especially suited to sharing data with
third parties or remote locations. |
| SMTP
(Simple Mail Transfer Protocol) |
A
standard protocol for transporting email messages between servers. |
Alarm
and error conditions can trigger an email or pager alert, enabling
faster dtection and resolution of system events. |
| SQL (Structured
Query Language) |
a
standard interactive and programming language for getting information
from and updating a database via queries. Queries take the form of
a standard command language that lets you select, insert, update,
or find out the location of data. |
Any
application requiring bidirectional sharing of data, especially for
older databases that do not support XML. |
| XML
(Extensible Markup Language) |
A
World Wide Web Consortium- (W3C) endorsed standard for document markup
and data exchange. Highly user-configurable means of defining data
and its structure. |
Users
can pull production data from the controller and display it on a Web
page, manipulate it using XSLT (Extensible Stylesheet Language: Transformation),
store it in XML-compliant databases, or use it with other XML-savvy
applications. |
