Product Q&A
- Q: Can this module act as both a Master and a Slave simultaneously?
- A: Yes, the SST-PFB3 architecture allows the module to run multiple protocol stacks concurrently on the same network.
- Q: Is this card compatible with 64-bit VME systems?
- A: It supports standard VME64 specifications for addressing and data width, ensuring broad backplane compatibility.
- Q: How is the module configured?
- A: Configuration is performed using Molex SST console software, which defines the PROFIBUS scan list and I/O mapping.
