SST-PFB3-VME-1 Single Channel PROFIBUS-DP VME Communication Board
Brand: Molex Woodhead (formerly SST)
Positioning: SST-PFB3-VME-1 VME bus rack PROFIBUS-DP dedicated communication interface card, widely compatible with GE Speedtronic Mark VI gas turbine/steam turbine control system (matched with the IS2020RKPSG2A power card you previously inquired about)
Hardware interface and bus specifications
- Backplane bus: standard VMEbus A24/D16, A16/D16 addressing, compatible with VME64 rack, 5V backplane power supply
- Front end external interface
- DB9 female head: PROFIBUS-DP bus (EN50170 standard)
- Debugging serial port: RS232, used for firmware download and network diagnosis
3. Hardware resources ：Onboard independent communication processor+flash memory, locally stored DP configuration, does not occupy host CPU computing resources; Channel electrical isolation, resistant to on-site interference
Full support for PROFIBUS protocol
- Working mode: Choose between DP master station/DP slave station, supporting simultaneous operation of Class 1 master station (periodic control) and Class 2 master station (upper diagnostic)
- Compatible versions: DP-V0 (cyclic IO data), DP-V1 (non cyclic parameter read/write, device diagnosis), FDL underlying message listening
- Full coverage of baud rate: 9.6k/19.2k/93.75k/187.5k/500k/1.5M/3M/6M/12M
- Data throughput: Single channel maximum 1984 byte input, 1968 byte output, meeting real-time interaction requirements for valves, frequency converters, and remote IO
