FAQ
- Can one test cover several RTs that each run on a different transfer period?
- Yes. Acting as BC, the module performs multi-cycle data processing and scheduling: each online RT can be assigned its own data-transfer period, and the module arranges the message frames and schedules transfers on those separate periods under one schedule — no need to split terminals into separate test rounds by period.
