Description
All I/O modules are connected to a high speed Bus Interface Module (BIM) via a proprietary bus system called ‘Railbus’ and one BIM can control up to 32 modules. The module carrier provides the transmission medium for the Railbus and by plugging a module onto a carrier, connections are made between the module and the bus. The connectors on the carrier also provide the power supply links to the module.
