FAQ
Q HMI vs SCADA?
A
HMI: local operation at a single machine or station. SCADA: plant-wide or multi-line supervision (PC platform + database + multi-client). Siemens WinCC Unified covers both.
Q HMI screen size?
A
5-7 inch: small machine, single station; 10-15 inch: standard line; 15-22 inch: complex processes, multi-window; 32+ inch: andon boards, shop-floor display.
Q Web HMI or classic?
A
Web HMI (Beckhoff TwinCAT HMI, Siemens WinCC Unified): browser access, cross-device, multi-user. Classic: fixed, stable, embedded. New projects prefer Web HMI.
