- Monitoring and Control System for Windows Based Software

0

Not just another Windows based software package. Rel-tek manufactures complete gas monitoring and control systems, including the powerful and easy to use Millennia-DX PC software. Millennia-DX is designed for those of us who don't have time to become computer experts, but who need a quality system with an easy, intuitive setup; modularity to enable the system to grow; fast, reliable communications; and low budget pricing.

Parameters: PC/Windows based software, computer, communication drivers and intelligent field I/O cards; 10-mile range hardwired, or unlimited with modem.

Millennia-DX (Version FT) is an enhanced version of the already powerful and easy-to-use EZ-Trol/DX™ real-time monitoring and control software. Version FT is a true (native) 32-bit application running on a Pentium PC under Windows 98, XP, or 2000 taking advantage of powerful 32-bit features and utilities within the latest Windows platforms.

The uniquely integrated software and hardware package provides a fast, capable monitoring and control system - specially engineered for high reliability and ease of use. Millennia-DX is written as one distinct program and eliminates the slow and often unreliable DDE links most competitors use for inter-module message transfer.

Field data communication speeds as high as 115k baud virtually eliminates polling delays, enabling PLC performance without the higher costs.

A. Overview-- The new Millennia-DX (Version FT) system runs much faster, with greater ease of setup, more visibility of status for the operator, enhanced security and with more powerful graphics and user interface features. The Millennia-DX software is backward-compatible with previous EZ-Trol/DX versions, permitting setup and configuration files to be imported without modification. Upgrading is automatic, adopting all previous setup files. However, this new FT version requires Windows 98, 2000 or XP and will not operate on Windows-3.1. or 95.

General Software Highlites:

  • System Menu provides easy access to all features and utilities. No longer buried beneath layers of windows, one click at the Windows tray brings this window/Menu to the front for easy click-on calls. A window on this menu bar lists all active operating functions for quick reference.
  • Printing has been enhanced to provide printout of all graphic and text based setup and viewing screens, including the Control Logic Editor and all data and status viewing windows.
  • All setup, data and control logs are saved in an industry standard (CSM) database format, permitting export to Excel and other popular data base programs.
  • Automatic backup occurs on exiting a setup menu, with all changes recorded as an audit trail for future reference. Automatic file backup to floppy is now standard.

B. Units Screen -- This defines the field I/O card types, addresses, I/O channel designations, data ranges, units and the like. Enhanced menu options includes a feature to quickly enable or disable all units (addressees) or selected ranges, rather than one at a time. A right click brings a simpler card type selection; just pick from a list.

Image

C. Password & Security -- Setup has been simplified and more logically organized for defined access. Any menu function can be protected, using hierarchical passwords.

Image

D. Signal Screen -- This is the utility where individual channels (analog or digital inputs or outputs) are identified and assigned to field I/O card addresses. A right click brings a menu of all available I/O card, showing all available channels, A left click assigns the sensor to a selected channel. Add any number of sensors using powerful Find/Replace and Copy/Paste utilities, with new sensors retaining all the same attributes as the sensor model used. A signal check utility shows if a signal is being used by the system before permitting modifications or deletions.

Image

E. Alarm and Status Screen -- This screen shows the current status of all outstanding alarm and control functions. A quick glance reveals the outstanding - un-acknowledged - alarms. The status screen has been reorganized for more concise visual information, usually without scrolling. Greater flexibility was added for customizing and prioritizing alarm events by color.

Image

F. Historical Trending and Data Logging --Threshold of value changes for logging is now easily modified by a simple global command, or by selecting groups of sensors. Local overrides are always possible. Logging groups and signal lists are now sorted for easier access. The Data Viewer utility has been seriously modified for easier setup and more precise viewing. Grids and units title/names for each color are displayed, in addition to the standard day/week/month time base selection as before. Printout is also easier, and graphs have a distinctively professional format.

Image

G. Script Editing -- A number of new commands were added providing better access to the Windows screen and file controls. Script library was expanded to include custom control strategies using intuitive, symbolic code.

Image

H. Control Logic Editor -- This unique and powerful utility depicts boolean control logic visually, using a menu of inputs and outputs with and/or gates, pulsers and timers in a schematic format showing 'virtual' connections and logic flow strategies. Color changes show active control paths for easily identifying the source and results for each control action.

Audio functions were added, providing wave file selections of bells, whistles, horns and even stored voice messages as output options. Script control for time on, time off, time delays, etc. were also added for invoking Windows commands as a basis for control actions and alarms. Grid size was cut in half to permit doubling the number of control lines per page, and with more command logic space per line. Speed of control scanning has been increased many fold, allowing even large systems to operate with fractional second timing.

Image

I. Window Viewer and Window Maker -- These utilities have been enhanced to add new capabilities, as well as to permit easier, more powerful setup and usage. New icons: Polyline and Polygon tools, permitting irregular, closed, straight line symbols having selectable fills and color options. A dynamic cursor feedback provides clear identification of selected elements and groups; flags show command names for easy reference. The icons can be grouped for dynamic display and control, as well as exporting to a library and importing as needed. Also, digital and analog meter icons can now be scaled to any size for special effects and easy viewing from a distance. Analog meter icons show tic marks, as well as max/min values.

A very useful Object Inspector window permits addressing and controlling icon elements within a group without ungrouping. The powerful screen editing tools now have Cut/Paste/Copy commands which greatly facilitates screen development with very professional results. Bitmap imports are also scalable, and screen animation tools along with realistic 3-D graphics are available.

J. Remote Link-- Remote access allows you to access real-time data over a local area network The Remote Access capability uses the TCP/IP protocol to transmit real-time data between remote workstations and the central computer. Each station must have a valid TCP/IP address defined for it. This is done from the Network Control panel in windows. A Remote Host workstation can send data to any number of client workstation. A Remote Client can connect to only one host (central computer) in the current version of the software. A Host can also be a client, therefore data can be daisy-chained from one computer to another.

K. Ethernet to LAN Communication -- a new feature on top of serial communication that was added to Rel-Tek Corporation control and monitoring software, Millennia/DX FT. It allows for Millennia/DX FT to communicate over LAN through Ethernet by sending and receiving data packets. Because Millennia/DX communication is over LAN, it doesn't have to be running on a computer that's directly connected to the hardwares as supposed to serial communication. This means Millennia/DX system can be run on any computers and communicate over LAN or ultimately the Internet (WAN) (see the diagram).

Image

L. FT Protocol -- FT stands for Fast Telemetry. This is our major enhancements to our original protocol. So, that overall communication between our hardware and the computer system speeds up the pooling cycle speed.
