Description
The Molex/Woodhead/SST 5136-PFB-ISA /ORN-PFB Profibus communication adapter module features a 9-pin D-sub connection and status led. SST-PBF3-PCI is the next generation
Profibus PCI card. Where possible, backward compatibility is feasible in keeping with the old 5136-PFB-PCI, but the new SST-PFB3-PCI is not a declining replacement for the existing one
5136-PFB-PCI card.
The 5136-pfb-isa and SST-PFB3-PCI cards can:
As DP slave
● As DP administrator
Send and receive FDL(Layer 2) messages
Support Master Class 2
● All the above modes are supported at the same time
Supports standard Profibus baud rates of 9.6K, 19.2K, 93.75K, 187.5K, 500K, 750K, 1.5M, 3M, 6M, and 12M.
Whereas the traditional 5136-PFB-PCI card’s controls (e.g., interrupts and resets) are handled by writes to the PCI configuration space (Section 2.4), this is no longer the case with the new SST-PFB3-PCI.
The SST-PFB3-PCI card is controlled by a separately mapped PCI memory area. This memory area is also used to access new features such as the ability to read LED status (Section 2.2). A bus standard
Newly designed configuration Spaces typically do not require host application writing; It is usually only up to the host system driver to determine where the card’s resources are allocated to the host system.
