SuperCAT

Practical field notes for the SuperCAT EtherCAT master (PCIe-833x / dongle) — from getting slaves recognized to reading IO and homing an axis.

Bus setup: scan, ESI & device recognition — why a slave isn’t recognized after a scan, and the -1014 fix.
EtherCAT IO & homing — register & bind the ECAT-2055 IO so homing catches ORG and OT protects the axis.
ESI download sources — a running list of official ESI download links per vendor, with versions and dates.
