SST-5136-PFB-ISA

The 5136-PFB-ISA card can:

• act as a DP slave

• act as a DP master

• send and receive FDL (layer 2) messages

• send and receive FMS messages

The card supports simultaneous operation in all these modes.

The card supports the standard ProfiBus baud rates of 9.6K, 19.2K, 93.75K,187.5K, 500K, 750K, 1.5M, 3M, 6M and 12M baud.

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 in16 Kbyte pages. The host determines which 16 Kbyte page of this sharedRAM 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 passinformation between the interface card and the application software runningin the host computer. This approach makes for a fast and simple connectionbetween host application and card software. The host computer uses theloader program included on the distribution disk to load a software moduleinto card memory.

In addition, the card has 512 Kbytes of sectored flash memory, for storage ofprograms and configuration data. The host computer uses the utility includedon the distribution disk to store a software module into flash memory.ProfiBus configuration information may also be stored in flash.
