System Architecture & Signal Flow
The QPI-GEG-201-H installs into the Series 90 backplane and acts as the bus master or slave gateway on the Genius Bus segment. The host CPU communicates with the module via the backplane bus; the module then manages all Genius Bus token-passing protocol, polling I/O blocks, collecting input data, and distributing output commands. Datagrams allow peer devices to exchange data independently, reducing host CPU overhead. The module’s dual-port architecture ensures deterministic scan times even under high bus load conditions.
Signal Flow: Host CPU → Backplane Bus → QPI-GEG-201-H Gateway → Genius Bus Segment → Distributed I/O Blocks (up to 31 nodes)

Technical FAQ
Q: Is the QPI-GEG-201-H compatible with PACSystems RX7i or RX3i?
A: The module is native to Series 90 architecture. PACSystems compatibility requires a Genius Bus Controller (GBC) module; consult your system integrator for migration planning.
Q: What is the maximum cable length for the Genius Bus segment?
A: At 153.6 kbps, maximum trunk length is approximately 750 m (Belden 9463 or equivalent shielded twisted pair). Reduce length at higher baud rates.
Q: Can this module operate as both bus master and slave?
A: Configuration is set via software parameters in the Series 90 programming environment (Logicmaster 90 or Proficy Machine Edition).
Q: Do you provide the GE datasheet or installation manual?
A: Yes. Contact support@konmask.com with your order reference to receive the official GE Fanuc documentation package.
Q: What is the lead time for this module?
A: Typically 3–7 business days for in-stock units; 2–4 weeks for sourced orders. Confirmed at quotation stage.
