C1300-0XX | Lightbus VME bus interface card

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.

Features

  • 16 bit VME bus slave
  • single or double card format available
  • Microprocessor (Siemens 80C166) implements the Lightbus communication procedure.
  • 4 kbyte dual-port RAM to the VME bus
  • representation of the I/O data in dual ported RAM
  • simple software interface using CDLs (communication description lists), status and control registers in dual ported RAM
  • initiation of up to 4 VME bus interrupts
