The radio communication links for the different cranes were isolated from each other by configuring different frequency hopping codes for each crane data link. The stationary 900-MB's were multi-dropped on an RS-485 line back to the host PC.
A smelter used a network of SCADALink 900-MBs
to monitor the status of their overhead cranes. Crane PLC status was
transmitted via the 900-MB to a corresponding 900-MB located at the end of the
1 mile corridor.
