CTI Janus Programmable Automation Controller IOG
11
Web Server Interface
The controller contains an embedded web server, which provides an interface to detailed information regarding
the controller configuration, operation, and history. The web server can be used to:
•
Obtain information about the product and application
•
Configure the product settings
•
Update product firmware
•
Perform file transfer operations
•
Access user-generated graphics pages (monitor and control application)
•
View diagnostic information (such as error and status info)
•
Access operational statistics
•
View Event Log
•
Supports user created web pages that access controller application data. (See Section
The web server can be accessed by entering the controller IP address in the URL box of your browser.
Online Change Support
The controller supports a comprehensive change facility that allows you to make extensive changes to the user
program, then download the changed program without bumping the I/O.
See the
Janus Workbench
Help for
detailed information and limitations.
Security
The controller employs a Secure Boot technology, which ensures the firmware loaded to the controller is an
authenticated CTI version. Access to the application program (using Workbench) and access to the web server can
be configured to require username/password authentication. You can also enable encryption between a web
browser and the controller web server.
Compatibility
The Janus Controller is designed to work in the same plant environment as the CTI 2500 Series PLC, supporting
many of the legacy interfaces. It is compatible with existing CTI 2500 Series and Siemens Series 505 local and
remote I/O and Profibus-DP I/O. It can function as an Ethernet CAMP server, allowing it to communicate with
existing HMI/SCADA workstations and CTI 2572/2572-A/2572-B communications modules. It can also act as a
CAMP client for peer-to-peer communications to existing CTI products. The Enhanced Data Cache Client protocol
facilitates high speed communications with CTI 2500 Series PLCs.
High Performance
All Janus Controllers are powered by an ultra-high performance SoC (System on Chip) with ARM®+ FPGA
architecture providing extreme I/O bandwidth with low system power requirements. This architecture provides
capability to simultaneously execute logic and I/O communications which translates to sub-millisecond cycle times
for many small applications.
