Crane Sentry System Adds Allen-Bradley Connectivity with Help from Real Time Automation’s 435NBX Gateway
Laser-View Technologies wanted to offer reliable, consistent Allen-Bradley PLC Connectivity in its Crane Sentry® Location Manager overhead crane positioning system. As the manu-facturer of the Crane Sentry® product line and authorized distributor of Dimetix laser distance sensors and accessories in the USA, customers had come to love the laser collision monitoring system as a cost effective solution to add semi-autonomous control to their overhead crane and hoist ap-plications. The solution is especially popular since it can ret-rofit into existing applications while utilizing the established drive systems. To meet the Allen-Bradley connectivity re-quests of their customers, Laser-View Technologies knew they had to find a way to interface the ASCII data from the Dimetix laser distance sensor. As Laser-View Technologies sought an answer, Real Time Automation offered a solution.
“It came down to this. None of the other solutions matched the value we found with the 435NBX,” said Steven Lubeck, president of Laser-View Technologies. “RTA was always ready with prompt re-sponses, units guaran-teed to be in stock and support beyond our expectation.”
The 435NBX gateway accepts the position data from both lasers over the two available RS-232 serial channels and delivers the measurement values directly to user de-fined tags in the data table of the Allen-Bradley PLC. There’s no message instruction or IO tree to mess with in the PLC. All the programmer needs to implement is a simple tag length based handshake to integrate the ASCII values.
Real Time Automation’s commitment to guaranteed stock and same-day order fulfillment meant Laser-View Technolo-gies wouldn’t have to worry about lead times that could cripple entire system integrations. “On a complex machine, even the smallest part can cause big headaches,” said Lubeck. “Finding quality vendors like Real Time Automation is paramount to our continued success.”
