5136-PFB-VME SST Profibus Programmable Control Board

The Molex / Woodhead / SST 5136-PFB-VME Profibus Interface Card can act as a DP slave, act as a DP master, and send and receive FDL (layer 2) 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, that handles the communication protocol and data formatting into the shared RAM.

The card has an additional 256 Kbytes of RAM which is shared with the host as either a single block of 256 Kbytes (linear addressing mode) or as one of sixteen, 16 Kbyte pages (paged mode). In paged mode, the host determines which 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 ensures a fast and simple connection between the host computer and the card software. In addition, the card has 512 Kbytes of sectored flash memory, for storage of programs and configuration data. ProfiBus configuration information may also be stored in flash.

ProSoft Wireless Protocol
ProSoft Wireless Protocol (PWP) offers versatility where a mix of control devices requires cooperation with each other. This involves sharing of information across the applications regardless of device or network type, often at high speed, and with high reliability. Wireless bandwidth utilization is optimized by using efficient communication methods. The protocol supports Unicast, Broadcast and Multicast group messaging. Efficiency is based on the fact each device on the “wireless” network can produce these types of messages and each device determines which of these messages to consume.
General Specifications – Radio Modules
These modules utilize a full function wireless network card, supporting RF data rates up to 11 Mbps. The modules function as a client, providing an ultra-fast wireless solution for the most demanding industrial applications.
These modules allow you to connect various field devices using different networks or protocols and share data between these devices “over-the-air.” This is accomplished by exchanging shared common database information over-the-air with ProSoft Technology’s efficient but powerful wireless protocol.
