Intelligence built for the machine room.
A rugged industrial display, a deterministic supervisory PLC and purpose-designed field interfaces—presented as one serviceable system.
This page shows design studies and candidate components, not photographed production assemblies. Final electrical ratings, enclosure design, compliance and released configurations remain subject to engineering validation.

VI industrial HMI
The proposed technician-facing panel displays status, event history and diagnostic views. Supervisory logic remains in the PLC.
Configuration under evaluation.
Hardware previously discussed with a panel-PC supplier. These are candidate specifications—not tested, purchased or certified product claims.
Candidate supplier configuration is separate from the Wecon LX3V/LX5S PLC selection and any protective-interface design. No released VI hardware specification is asserted.
Designed around installation and troubleshooting.
Modular field interface
Replaceable and clearly labeled input conditioning, rated for the specific field signals after engineering review.
Serviceable I/O
Accessible terminals, cable management and documentation for on-site verification without hiding critical connections.
Separation of authority
Deterministic PLC logic owns defined control behavior. The HMI shows evidence; VI Assistant is advisory only.
