Mitsubishi Application Examples

Data-Linc Provides Robust Wireless Communication
Between Central Control and a Mitsubishi A3ACPU PLC
for Steel Mill Coke Pusher Application

Steel mill coke pusher wireless Ethernet applicationData-Linc 2.4 GHz wireless Ethernet modems are being used to transfer data for one of a southwestern China steel mill's mobile coke pushers. A Mitsubishi A3ACPU PLC with GPP Control Software communicates with the Master Control PC to provide data collection, protocol conversion and program transferring for a SCADA system. This provides data monitoring, screen display, alarm, real-time trend display and data archiving despite the presence of dust, vibration, corrosive air and high temperatures.

Data-Linc wireless modems interface with Mitsubishi Series A2 PLCs to solve Huaneng Coal Conveyer SCADA disconnect problem

Huaneng China's power company had been using wire cable to monitor and control its two coal conveyer mobile platforms. Because the platforms moved back and forth along railroad tracks, the data cable frequently disconnected which interrupted operation resulting in costly downtime.

To eliminate these recurring breaks in service, Huaneng replaced the cable with three SRM wireless serial 2.4 GHz modems. They connected a modem to each of two Mitsubishi Series A2 PLC on the two mobile platforms. These Remote units transfer data to the Control Center PC via a Master SRM wireless serial 2.4 GHz modem (See diagram.). Because the Data-Linc Group system operates transparently, Huaneng did not need to reconfigure nor reprogram the PLCs. The company is now enjoying trouble-free operation.

Data-Linc modems undergo extensive testing with Mitsubishi PLCs and pass with flying colors

Data-Linc Group and H.D. Campbell, the Mitsubishi Distributor in Seattle, collaborated in a test program interfacing Data-Linc SRM6000 frequency hopping spread spectrum license-free radio modems and DLM4000/DL dial-up modems with the Mitsubishi FX2N PLC. Data-Linc Radio Modems support both Ethernet (TCP/IP) and serial connectivity at a range of up to 35 miles without Repeaters.

Additional tests with the older model FX PLC have also been undertaken to settle all potential compatibility issues.

Mitsubishi Distributors are now quoting Data-Linc wireless, dial-up and other Data-Linc modems for applications involving Mitsubishi PLCs.
