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.

Remote Link Screen

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.
Ethernet to LAN Communication Setting

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 diagrams below)

Remote Scanning communication Diagram

Remote Network Scanning

Remote scanning diagram shows that Millennia system running on a remote computer can communicate to the hardwares through LAN-Internet-LAN connection setup. As shown on the diagram, remote scanning was tested on a computer system that was at least 40 miles away from our company, where all the hardware was located i.e. I/O cards, sensors, outstations, etc. According to our test, communication was nearly perfect (99% to be exact).

Wired LAN DX-Com Card - is a specially developed card for LAN communication that receives network data packets, converts them to Rs485 bytes for local communication and vice versa.

DX4404 - is a input/output card that reads sensors' signal and relays to Millennia system. This perticular card has 4 analog input, 4 digital input, 0 Analog output and 4 digital output. Hence, DX4404.

All the other components shown in the diagrams are devices that make up LAN connections and the Internet - router, DSL modem, etc.

Ethernet to LAN communication Diagram

Ethernet To LAN Communication

Ethernet to LAN communication diagram shows that Millennia system can communicate over LAN connection to the hardwares. Every hardware and devices that need to be communicating with our system has to be connected to the DX-COM-LAN card as shown above. DX-COM-LAN card is specially designed for LAN communication by Rel-Tek Corporation. It directly connects to your LAN and provides a communication path between Our Millennia system and the hardware. DX-COM-LAN card receives network packets from Millennia System and converts them to RS485 data bytes. When the I/O card replies back to Millennia, DX-COM-LAN card takes the RS485 data bytes converts them to Network packets to be sent out to Millennia system.

DX-COM-LAN - is a specially developed card for LAN communication that receives network data packets, converts them to Rs485 bytes for local communication and vice versa.

U1 DXCARD - Input/Output(I/O) card with address 1.


U10 DXCARD - (I/O) card with address 10.

FT Protocol

By selecting one of the type (FT Protocol) option from pull-down-menu, Millennai/DX FT system can communicate with the hardware with faster DX-BUS polling cycle speed.

117 sensors per second

That's the processing speed of Rel-Tek's new "Millennia-FT" software and telemetry. Speed was measured on an actual 18-sensor system, clocking 392 scan cycles per minute - an cycle repeat delay of 0.15 sec. Equally significant is that after 3 days running and 30 million data updates there were zero errors. Not one. That's a communication reliability of 99.9999967%, and counting.

This recent test confirms the results of a very large system test conducted last year. That system was fully loaded and had an update delay of 3.5 sec. "FT" stands for "Flash Telemetry", a theoretical idea. On implementation, though, it far exceeded our expectations.

Communications is the backbone of any monitoring system. Without good speed and reliability, a telemetry system isn't worth anything. Rel-Tek released its "Flash Telemetry" monitoring and control package last year. To date, there are four systems operating in underground US coal mines. Another system is scheduled for shipment July 1, 2010.

The extreme speed and reliability of this "FT" technology reflects Rel-Tek's software prowess and the clever integration of telemetry with field outstations. Akin to ZIP files, the data stream is compacted for max density. The actual data rate is 19.2KB, transmitted over inexpensive twisted-pair cable.

High-speed repeaters are placed at one-mile intervals, extending a system to 20 miles straight ahead, while handling lateral branching as required. LAN, fiber and wireless WiFi data-highway interfaces are also available.

Our gamut of MSHA-approved and classified intrinsically safe sensors use generic 4-20ma analog signals, converted at the outstation using 12-bit resolution for just 0.0244% digitizing error. Sensors include CO, O2, CH4, smoke, temp and pressure. Air velocity, humidity, vibration, H2S, SO2, and CO2 are also available for use with the system. Generic is good.

MagiKal is a powerful utility for automatically calibrating hard-to-reach sensors - i.e. high overhead, in pits, over conveyors, inside silos, under unsupported roof, behind seals and such. It runs under the Millennia-FT package. Calibrations are implemented on a monthly schedule.

Other news -- Applications of Millennia-FT and gas sensors in "Refuge Alternatives" will include MagiKal to maintain sensor accuracy over years on standby, unattended. MSHA approval for Rel-Tek's "awAIR" shelter monitoring systems is pending. Included, is networking with the surface.

Large and small mines can benefit from these new technologies.
