SST SST-PFB-CLX Profibus Interface Card

The card has an onboard Intel i960 processor with 512 Kbytes of local RAM.

The card has an additional 256 Kbytes of RAM that is shared with the host in

16 Kbyte pages. The host determines which 16 Kbyte page of this shared

RAM is mapped into the host memory by writing to a register on the card.

This block of memory contains all the tables and buffers that are used to pass

information between the interface card and the application software running

in the host computer. This approach makes for a fast and simple connection

between host application and card software. The host computer uses the

loader program included on the distribution disk to load a software module

into card memory.

In addition, the card has 512 Kbytes of sectored flash memory, for storage of

programs and configuration data. The host computer uses the utility included

on the distribution disk to store a software module into flash memory.

ProfiBus configuration information may also be stored in flash.
