What Nexus does and does not control
Understand the boundary between monitoring, engineering evidence and separately governed physical actions.
Confirm your site, role and source revision. Follow the local procedure and responsible engineer for physical actions.
Safe interpretation
SCADA design and runtime render declarative, quality-marked data. Evidence workspaces store and review records. Advisory AI proposes investigations or improvements for a human to evaluate. These activities do not download logic, force outputs or bypass local safety systems.
Physical work
Use approved site procedures, qualified personnel, local control-system tools, isolation practices and commissioning records for any physical task. Existing supervisory-command features are a separate, commissioned and governed workflow; their presence does not grant general PLC write authority.
- Stop if a requested workflow appears to require an unapproved equipment action.
- Never treat a simulated result as field acceptance.
