5136-PFB-104 Profibus通信适配器模块

5136-PFB-ISA卡可以:
•作为DP奴隶
•做一个DP大师
•发送和接收FDL(第2层)消息
•发送和接收FMS消息
该卡支持在所有这些模式下同时操作。
支持9.6K、19.2K、93.75K、187.5K、500K、750K、1.5M、3M、6M和12M波特率的ProfiBus标准波特率。
该卡有一个板载英特尔i960处理器和512 kb的本地内存。
该卡有一个额外的256 kb的RAM，在16 kb的页面中与主机共享。主机通过写入卡上的寄存器来确定这个共享RAM的哪个16kbyte页映射到主机内存中。
这个内存块包含所有的表和缓冲区，这些表和缓冲区用于在接口卡和主机上运行的应用软件之间传递信息。这种方法使得主机应用程序和卡软件之间的连接快速而简单。主机使用分布磁盘上包含的加载程序将软件模块加载到卡存储器中。
此外，该卡具有512 kb的扇区闪存，用于存储程序和配置数据。主机使用包含在分发磁盘上的实用程序将软件模块存储到闪存中。
ProfiBus配置信息也可以存储在flash中。

5136-DN-PC

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 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.
