Could be a job for a hybrid Mesa/Pico system. There are Mesa smart-serial cards with IO typically in chunks of 48 and one FPGA card can connect 8 cards per port. So 3x8x48=1152 IO points is doable. (Theoretical max of the drivers is 2944) But, the update rate is the servo thread rate. Fast IO can't be on smart-serial. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
