SRM6100 Wireless Serial Radio Modems Revamp Operations in a Power Generation Plant in China

Mounted antenna (in forground) allows modems to transmit data between central control and ship-side coal unload manchines.
A power generation plant's coal-unload system that became operational in August of 1996 in China was brought into the 21st century by a recent revamping of the system. A PLC and supervisor PC provide the control and monitoring while an OMRON-200 PLC operates in the unload machine driver room. Ten mobile coal-unloaded machines work on ships during the coal handling process. Since 1996 coal-unload machines communicated with the control room through a slide wire with limited data transfer. Not only was data communication limited, but the slide wire was costly, difficult to maintain requiring continual maintenance for optimal performance. The revamped system utilizes Data-Linc's SRM6100 wireless serial radio modems which eliminate the need for costly slide wire.

Since the update the operator can read the parameters, movements and operations of the individual remote coal-unload machines and send control commands to them. Maintenance personnel in the control room can change the program on the remote PLC at the unload machine; additional PCs in the control room can share data from the unload machines; the PLCs have the capability to receive control and program commands from the control room; and if the primary PC (PC1) has problems, a switching circuit switches the SRM6100 wireless modem to another PC, ensuring the RF communication between control room and coal-unload machines.

Wireless RF Modems Extend Network Distance and Provide Exceptional Noise Immunity in Remote Control and Monitoring Applications

Application Description

The ability to transmit data between remote locations reliably, regardless of weather conditions is a difficult and expensive project using conventional dedicated line, wire, or fiber optic network media. Extending the distance of Omron's Ethernet and Host Link networks without jeopardizing the reliability or integrity of the system is a key requirement in solving remote control and monitoring applications. Radio modems using spread spectrum technology from Data-Linc Group can provide a cost effective, reliable solution for these remote applications.

Omron/Data-Linc Group Solution Features and Benefits

    Cost effectively transmit information reliably over 20 miles, with extended distances possible using Repeaters!

    Reliable extension of Omron's Host Link and Ethernet Networks

    Exceptional data reliability and integrity and the robust design which results in superior correlation/sensitivity and signal/noise specifications.

    Operating temperature range of -40°C to +75°C for all SRM Series modems and industrial grade shock/vibration immunity.

    Serial version data rate of 115.2Kbaud, thereby providing substantial "cushion" in the event of interference, to protect and maintain PLC line speeds in spite of significant impact upon the radio throughput.

    Ethernet version's 100kbps data rate supports ranges of up to 35 miles with omni directional antennas and without Repeaters (multiples of this distance with Repeaters)

    Easy installation.

Omron/Data-Linc Group Advantages

    Omron's Host Link protocol has been performing for over 20 years in harsh industrial environments.

    Both Omron's Host Link and Ethernet network protocols are open and fully published.

Industries and Applications

    Mobile Machinery provides flexibility in relocating machinery often without installing costly communications cable.

    Rotating machinery and equipment where wiring is difficult due to the movement of the mechanics.

    Mining, Metals, Oil and Gas, Pulp and Paper, Power/Utilities, Transportation.

    Remote Terminal Units (RTUs) and Pump Stations in the water/wastewater and pipeline industries.
