Up to 255 distributed Lightbus input and output modules can be connected to the VME bus with a single C1300 interface card. Fibre optics carry data at 2.5 Mbaud between the VME bus rack and the industrial peripherals, rapidly and without interference.
The interface card has its own communications processor and 4 kbytes of dual ported RAM to the VME bus, in which the process image of the connected Lightbus modules is represented in real-time. Up to eight priority-controlled logical communication channels and convenient interrupt handling permit a simple program interface and relieve the load on the VME bus CPU.
Software solutions are available for integration in OS/9 and other operating systems for VME computers.
