NetLinxTM Without Wires: Wireless Ethernet Improves Plant Productivity
Rockwell Automation's NetLinx network architecture provides seamless communication between Ethernet, ControlNet and DeviceNet. Now with Data-Linc Group's SRM6200E Ethernet Radio Modem, industrial plants may gain the benefits of NetLinx without additional cable installation. Designed for control, configuration and data collection applications, the NetLinx architecture adds broad capability to Ethernet in Allen-Bradley systems. By providing a highly reliable wireless Ethernet connection, peripherals may communicate on the plant network without the expense and delay of cable installation.
The wireless connectivity also solves the problem of communicating to devices where cable installation is impossible such as portable workstations and devices installed on moving platforms. In the past, these devices would be isolated from the plant network. For example, a portable PC may now connect to the network virtually anywhere in the plant. This permits plant engineers to work at the problem location while having full access to the Rockwell Automation network. Remote locations up to 20 miles away (farther using Repeaters) may also connect to the plant network using the SRM6200E. This eliminates the cost and unreliability of leasing telephone lines.
Applications for the SRM6200E Radio Modem include:

Data-Linc Group Radio Modems Featured in A-B Journal Article
In the A-B Journal, Data-Linc Group is featured in a Partner Application article. Data-Linc Group was instrumental in developing a data acquisition system for Victor Valley Wastewater Reclamation Authority in Southern California. Data-Linc successfully integrated Allen-Bradley PLC-5s and MicroLogix programmable logic controllers with Data-Linc radio modems and wireless Ethernet modems for accurate, reliable and near real-time data acquisition.
This scalable, high-speed, multi-tier, multi-drop radio frequency communications network delivers precise measurements quickly. Victor Valley engineers can turn pumps on or off, control water pressure and adjust flow levels from a computer in the main station, saving time and labor. "I can even monitor and make adjustments to the pumps from my PC at home so I don't have to send somebody out there," said Bruce Correia, application engineer, Victor Valley Wastewater Reclamation Authority.

Wireless ControlLogix With Data-Linc Ethernet Radio Modems
Data-Linc introduces license-free data communications for the Allen-Bradley ControlLogix platform utilizing the SRM6200E Ethernet Radio Modem (10Base-T, 10Base-FL, TCP/IP) providing exceptional data reliability and integrity as a result of its Smart Spectrum frequency hopping spread spectrum technology. The important advantages of industrial Ethernet communications, including ease of connectivity and multiplexing, make the Data-Linc SRM6200E an ideal solution for interfacing with Ethernet capable industrial automation equipment. The SRM6000 Serial radio modem and the SRM6200E will be both be available for rack mount.
Allen-Bradley Hands-on Training Features a SCADA Application Using Data-Linc Radio Modems
Six half day hands-on training sessions, presented by Allen-Bradley's Automation Specialist Ken Roach, focused on a SCADA application incorporating a DF1 multidrop network as controlled from an RSView Master station. Rockwell Automation asked Data-Linc to supply its SRM6000 license free radio modems for these wireless demos which were part of the three day SCADA Seminars they conducted in six west coast cities from San Francisco to Seattle during May and June, 2000. Topics included RSView and DF1 fundamentals, remote device configuration, configuring the RSLinx DF1 Polling Master Driver, using RSView for system monitoring and control, tuning DF1 parameters, system troubleshooting, tips on minimizing system disruption due to missing remotes and incorporating a Remote programming station. A diagram of the demo system, as well as other diagrams showing Data-Linc modems interfaced with Allen-Bradley Equipment, can be seen by going to our Allen-Bradley diagrams section.
Data-Linc Wireless Modems Let You Install Allen-Bradley PanelView "Anywhere You Need It"
The space-saving design of the Allen-Bradley PanelView, available in a flat panel or 14-inch CRT, makes it very convenient for use in monitoring and control applications on the shop floor. Unfortunately, in the typical industrial environment, wiring it to a PLC that isn't located in the same area is rarely as convenient. Rather than investing time and money into running cable or worrying about cabling distance limitations, why not consider a wireless alternative instead?
A pair of Data-Linc license-free SRM6000 Radio Modems can connect your PanelView Master to a remote DF1 Channel 0 device such as a PLC even at distances up to 35 miles! Reliable communication even in high interference is assured because of Data-Linc's Smart Spectrum technology that uses advanced frequency hopping and error correction. The modems are capable of high-speed data rates including 19.2 kbps, the typical data rate for PanelView. The SRM6000 comes factory pre-configured for your specific application to ensure easy installation and operation.

Allen-Bradley MicroLogix 1000 & 1500 Controllers as DF1 Half-Duplex Remotes With Data-Linc LLM1000 & the New LLM1100 FSK Wireline Modems
DF1 half-duplex protocol and RTS/CTS hardware handshaking have been added to the RS-232 serial ports of Allen-Bradley MicroLogix controllers. This improvement allows these popular controllers to be used as half-duplex Remotes to a New Platform PLC-5, SLC-5/03, /04 and /05, or other DF1 half-duplex Master devices.
MicroLogix 1000 controllers prior to Series D did not have this half-duplex functionality. All MicroLogix 1000 controllers with analog, and all MicroLogix 1500 controllers have this functionality.
The Data-Linc LLM1000 and LLM1100 units are compact, cost-effective long-line modems that operate over any dedicated twisted pair wire. They have a maximum data rate of 1200 baud in half-duplex mode for multi-drop applications. The LLM modems require hardware handshaking
