Description
The SST Profibus interface card connects your VMEbus computer to Profibus DP-V0, DP-V1 and FDL (layer 2) networks. It provides high-speed deterministic communication between automation systems and their decentralized peripherals.
The SST Profibus VME interface card connects the following to Profibus:
- VME based programmable controllers
- VME based motion controllers
- VME based computers
The SST Profibus VME interface card interfaces with the host processor through shared dual ported memory. A fully documented host memory interface is provided. The card does not require external libraries, which simplifies custom driver development in your chosen operating system. DOS example programs with C source are included with each card to assist you with your software development.
Features
- Simultaneous execution of Profibus DP Master, DP Slave and FDL (layer 2)
- Manages PROFIBUS DP-V1 services
- Supports all standard Profibus baud rates: 9.6 Kbaud to 12 Mbaud
- Supports 16-bit transfers (VME D16) with both VME A24 (standard) and A16 (short I/O) address transfers
- Two versions of network interface cards provide the option of connecting to one or two independent Profibus networks
- Diagnostic LEDs for system status, watchdog timeout, and communications status
